Causes the motor to heat up
1.The ambient temperature is too high. If the ambient temperature exceeds 40 ℃, the motor temperature will rise.


2. The surrounding environment is seriously polluted by dust. Motors operating for a long time in this environment absorb a lot of dust, which blocks the gap between the coils at the end and the ventilation holes of the iron core (if the bearing leaks oil, the blockage is more serious), resulting in a greatly reduced air intake and overheating of the motor. .


3. The driven machinery fails (with friction or jamming), the stator and the rotor collide, the motor makes a metal impact sound, and even causes the motor to get stuck and does not rotate, causing the motor to over-current and heating, the temperature of the iron core rises rapidly, serious When the motor smokes, or even the coil burns.


4. Short circuit between cold air and hot air. For centrifugal fans, because the gap between the windshield of the end cover and the fan is too large, the low-pressure wind and the high-pressure wind are short-circuited, which reduces the air volume entering the motor and causes the motor to overheat.


5. The power supply voltage is too high. The motor operates within a 5~+10% change in the rated voltage, and the rated output can be kept unchanged. If the power supply voltage exceeds 10% of the rated voltage, the magnetic flux density of the iron core will increase sharply, and the motor will overheat due to the increase in iron loss.


6. The power supply is out of phase, and the motor winding or wiring is disconnected in one phase, so that the motor only works in two phases. If the power supply is out of phase, causing the single-phase operation of the motor, the windings of the motor will be rapidly heated and burned in a short time.


7. The cooler of the motor fails, or the air leakage is not strictly blocked, and the hot air directly leaks into the cold air area, which increases the air temperature of the motor population and causes the motor to overheat.


8. When the indoor exhaust system fails, the hot air discharged by the motor cannot be quickly discharged, and is immediately sucked in by the motor, causing the motor to overheat.


9. Motors with axial flow fans, if the fan rotates in the opposite direction, will also cause the motor to overheat. Excessive load. The windings are partially short-circuited or grounded, the motor is overheated locally in light cases, and the insulation is burned out in severe cases, emitting burnt smell or even smoke.


10. The external wiring of the motor is wrong, and there are two situations as follows: (1) The △ connection should be mistakenly connected to the Y connection, so that the current is very small at no-load, although the load can be driven at light load, but the current exceeds the rated value, so that The motor is hot. (2) The Y connection method should be mistakenly connected to the △ connection method, so that the current may be greater than the rated current at no-load, so that the temperature of the motor rises rapidly.


11. If the fluctuation of the power supply voltage is too large, the fluctuation range of the power supply voltage should be controlled between -5~10%, otherwise the load of the motor should be controlled. After overhaul, the number of turns of the coil is wrong or a certain pole, phase and group wiring are wrong.


12. After the overhaul, the wire section is smaller than the original section.


13. The stator and rotor iron cores are seriously dislocated. Although the no-load current is three-phase balanced, it is greater than the specified value.


14. The squirrel-cage rotor is broken or defective. The temperature of the iron core rises rapidly after the motor runs for 1~2h, and even exceeds the winding temperature. When it is heavily loaded or fully loaded, the stator current exceeds the rated value.


15. The welding point of the rotor winding of the wound motor is de-soldered, or the welding is not good during inspection, which causes the rotor to overheat and the speed and torque decrease significantly.


16. The motor winding is damp, or there is dust, oil, etc. attached to the winding, so that the insulation is reduced.


17. The motor starts too frequently in a short time.

Troubleshooting methods:


1.If it is a new motor, the wiring should be checked first; if the wiring is ok, it should be determined whether the motor is overloaded.


2. If the motor runs normally for a period of time, first check whether the fan is normal.


3. If the heat dissipation is normal, the three-phase current should be checked to see if there is a phase loss. If there is a phase loss, the power supply should be cut off immediately to determine whether the winding is open circuit or there is a power supply problem.


4. If the power supply is normal, check whether the position of the stator and rotor is correct, and whether the mechanical transmission is stuck. The motor should be disassembled to check whether there are traces of sweeping on the iron core, find out the reason, and deal with it.


5. If there is no problem mechanically, measure the DC resistance of each phase of the winding to see if there is a short-circuit point, use a megohmmeter to check whether the winding is grounded, and clean and dry the motor.


6. For the squirrel cage rotor, check whether the rotor is broken or defective, and re-weld or replace the rotor.


7. For the winding rotor, check whether the DC resistance of the rotor winding is normal and whether the welding points are loose.

Optimization measures


Often, we can improve the environment, optimize the working process of the motor, and install thermal protection devices to prevent the motor from overheating:


1.First, improve the operating environment of the motor. The ventilation and cooling conditions should be improved. If the environment is not easy to change, the motor with a higher heat resistance level should be replaced.


2. Optimize the motor startup and operation process to avoid frequent motor startup.


3. Adopt effective overheat protection device to avoid motor overheating and burn out, generally there are the following types:


(1) Use melt or air breaker as short-circuit protection device, and the protection characteristic curve is matched with the heating characteristic curve of the motor.


(2) Use thermal relays, etc. as the overload protection device of the motor, and the protection characteristic curve matches the heating characteristic curve of the motor.


(3) A temperature protection device is installed in the stator winding, and the circuit is automatically cut off when the motor is close to the maximum allowable temperature.


(4) A phase failure protection device is installed in the control circuit of the motor, and the power supply of the motor is cut off when the phase is disconnected.


(5) Install a low-voltage protection device in the control circuit, and cut off the power supply when the voltage is lower than a certain value. There may be other reasons for the heating of the motor, but we usually use the motor correctly in strict accordance with the operating procedures, maintain the motor correctly, make the surface of the motor clean, the current does not exceed the rated value, the vibration value is within the range, the running sound is normal, and the bearing is correct. Maintenance, etc., the service life of the motor will be extended.

The brushless DC motor is developed on the basis of the brushed DC motor. It has the advantages of stepless speed regulation, wide speed regulation, strong overload capacity, good linearity, long life, small size, light weight and large output. It solves a series of problems existing in brushed motors, and is widely used in various fields such as industrial equipment, instrumentation, household appliances, robots, and medical equipment. Because brushless motors do not have brushes for active commutation, an electronic commutator is required for commutation. What the brushless DC motor driver accomplishes is the function of this electronic commutator.


#unit-i77vWdA7EErkBKP .ce-image_inner{justify-content:center;}#unit-i77vWdA7EErkBKP .ce-image{height:100%;width:100%;--image-effect:2;}









#module-ocfRA0Wwm81Ll{padding-top:1vw;padding-bottom:1vw;}

Mainstream control methods of brushless DC motors:


Now there are three main types: FOC (also known as vector frequency conversion, magnetic field vector directional control), square wave control (also known as trapezoidal wave control, 120° control, 6-step commutation control) and sine wave control. So what are the advantages and disadvantages of each of these three control methods?


#unit-Viz1JRttQScG3na .ce-image_inner{justify-content:center;}#unit-Viz1JRttQScG3na .ce-image{height:100%;width:100%;--image-effect:2;}









#module-8Vv7HMScGqxId{padding-top:1vw;padding-bottom:1vw;}

Square wave manipulation:


The square wave control uses a Hall sensor or a non-inductive budget algorithm to obtain the position of the motor rotor, and then commutates 6 times (one commutation every 60°) within a 360° electrical cycle according to the rotor position. Each commutated azimuth motor outputs a force in a specific direction, so it can be said that the azimuth accuracy of square wave manipulation is electrical 60°. Because the phase current waveform of the motor is close to a square wave under the control of this method, it is called square wave control.
The advantage of the square wave control method is that the control algorithm is simple, the hardware cost is low, and a high motor speed can be obtained by using a controller with ordinary functions; the disadvantage is that the torque fluctuation is large, there is a certain current noise, and the power cannot reach the maximum value. . Square wave control is suitable for occasions that do not require high motor rolling function.

#module-JYN0MCCvILzOB{padding-top:1vw;padding-bottom:1vw;}

Sine wave manipulation:


The sine wave control method uses the SVPWM wave, the output is a 3-phase sine wave voltage, and the corresponding current is also a sine wave current. This method does not have the concept of square wave control commutation, which may be considered as an infinite number of commutations in an electrical cycle. Obviously, the sine wave control is compared with the square wave control, the torque fluctuation is smaller, the current harmonics are less, and the control feels more "delicate", but the functional requirements of the controller are slightly higher than the square wave control, and the motor power cannot be used. to the maximum value.


#unit-BnUl3U169ONW1HN .ce-image_inner{justify-content:center;}#unit-BnUl3U169ONW1HN .ce-image{height:100%;width:100%;--image-effect:2;}









#module-9NS7yxvJ5gLiO{padding-top:1vw;padding-bottom:1vw;}

FOC control:


The sine wave control completes the control of the voltage vector and directly controls the size of the current, but cannot control the direction of the current. The FOC control method can be regarded as an upgraded version of the sine wave control, which completes the control of the current vector, that is, the vector control of the motor stator magnetic field.
Because the direction of the motor stator magnetic field is controlled, the time between the motor stator magnetic field and the rotor magnetic field can be kept at 90° to achieve the maximum torque output under a certain current. The advantages of the FOC control method are: small torque fluctuation, high power, low noise, and fast dynamic response; the disadvantages are: high hardware cost, high requirements for controller functions, and matching motor parameters.


Which method is more suitable for future development?


FOC is now the best choice for efficient control of brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM). FOC precisely controls the size and direction of the magnetic field, so that the motor has stable torque, low noise, high power, and high-speed dynamic response. Because of the obvious advantages of FOC, it has gradually replaced the traditional control method in many applications, and has attracted much attention in the sports control profession.


The typical control block diagram of FOC is as follows. In order to obtain information such as the orientation of the motor rotor, the motor speed, and the current size as a response, it is necessary to first collect the motor phase current, perform a series of mathematical transformations and budget algorithms on it, and obtain a decoupled, easy-to-control response quantity. Then, the dynamic adjustment is performed according to the error between the reaction amount and the target value, and finally a 3-phase sine wave is output to drive the motor to roll.
FOC can be divided into sensored FOC and sensorless FOC according to whether the motor has a sensor or not.
Regarding the sensored FOC, because the sensor of the motor (usually the encoder) can reflect the orientation information of the motor rotor, the orientation budget algorithm can not be used in the control. Said that the control function is often required to be higher.


Regarding the sensorless FOC, because the motor does not have any sensor, the position information of the motor rotor cannot be obtained by simply reading the measurement value of the sensor. Therefore, in the control, it is necessary to collect the motor phase current and use the position budget algorithm to calculate the rotor position. Although the control of the sensorless FOC is difficult, it can prevent the risk of sensor failure, save the cost of the sensor, and simplify the wiring between the motor and the driver board. Now, non-inductive FOC is mostly used in fan occasions.

The performance of motor energy consumption is mainly in the following aspects



1.First, the motor load rate is low.
Due to the improper selection of the motor, excessive surplus or changes in the production process, the actual working load of the motor is far less than the rated load, and the motor that accounts for about 30% to 40% of the installed capacity runs under the rated load of 30% to 50%. Efficiency is too low.


2.Second, the power supply voltage is asymmetric or the voltage is too low.
Due to the unbalance of the single-phase load of the three-phase four-wire low-voltage power supply system, the three-phase voltage of the motor is asymmetrical, and the motor generates negative sequence torque. Losses in the operation of large motors. In addition, the grid voltage is low for a long time, which makes the motor current in normal operation too large, so the loss increases. The greater the three-phase voltage asymmetry, the lower the voltage, the greater the loss.


3.The third is that the old and old (obsolete) motors are still in use.
These motors use class E insulation, are bulky, have poor starting performance, and are inefficient. Although it has undergone years of renovation, it is still in use in many places.

4.Fourth, poor maintenance management.
Some units do not maintain the motors and equipment as required, and allow them to run for a long time, which makes the loss continue to increase.
Therefore, in view of these energy consumption performance, it is worth studying which energy saving scheme to choose.


#unit-i77vWdA7EErkBKP .ce-image_inner{justify-content:center;}#unit-i77vWdA7EErkBKP .ce-image{height:100%;width:100%;--image-effect:2;}#unit-i77vWdA7EErkBKP{padding-top:1vw;padding-bottom:1vw;}











There are roughly seven types of motor energy-saving solutions



1. Select energy-saving motor
Compared with ordinary motors, the high-efficiency motor optimizes the overall design, selects high-quality copper windings and silicon steel sheets, reduces various losses, reduces losses by 20%~30%, and improves efficiency by 2%~7%; payback period Usually 1-2 years, some months. In comparison, the high-efficiency motor is 0.413% more efficient than the J02 series motor. Therefore, it is imperative to replace the old electric motors with high-efficiency electric motors.

2. Appropriate selection of motor capacity to achieve energy saving
The state has made the following regulations for the three operating areas of three-phase asynchronous motors: the economic operation area is between 70% and 100% of the load rate; the general operation area is between 40% and 70% of the load rate; the load rate is 40% The following are non-economic operating areas. Improper selection of motor capacity will undoubtedly result in waste of electric energy. Therefore, using a suitable motor to improve the power factor and load rate can reduce power loss and save energy.


3. Use magnetic slot wedge instead of original slot wedge
The magnetic slot wedge mainly reduces the no-load iron loss in the asynchronous motor. The no-load additional iron loss is generated in the stator and rotor iron core by the harmonic magnetic flux caused by the cogging effect in the motor. The high-frequency additional iron loss induced by the stator and rotor in the iron core is called pulse vibration loss. In addition, the teeth of the stator and rotor are sometimes aligned and sometimes misaligned, and the magnetic flux of the tooth cluster on the tooth surface fluctuates, which can induce eddy currents in the tooth surface line layer, resulting in surface loss. Pulse vibration loss and surface loss are collectively called high-frequency additional losses, which account for 70% to 90% of motor stray losses, and the other 10% to 30% are called load additional losses, which are generated by leakage magnetic flux. Although the use of magnetic slot wedges will reduce the starting torque by 10% to 20%, the iron loss of the motor using magnetic slot wedges can be reduced by 60k compared to the motor using ordinary slot wedges, and it is very suitable for no-load or light-load starting motor transformation .


#unit-1e5O7TXue71GApX .ce-image_inner{justify-content:center;}#unit-1e5O7TXue71GApX .ce-image{height:100%;width:100%;--image-effect:2;}#unit-1e5O7TXue71GApX{padding-bottom:1vw;padding-top:1vw;}











4. Adopt Y/△ automatic conversion device
In order to solve the waste of electric energy when the equipment is lightly loaded, on the premise of not replacing the motor, a Y/△ automatic conversion device can be used to achieve the purpose of saving electricity. Because in the three-phase AC power grid, the voltage obtained by the different connection of the load is different, so the energy absorbed from the power grid is also different.


5. Motor power factor reactive power compensation
Improving power factor and reducing power loss are the main purposes of reactive power compensation. The power factor is equal to the ratio of active power to apparent power. Usually, a low power factor will cause excessive current. For a given load, when the supply voltage is constant, the lower the power factor, the greater the current. Therefore, the power factor is as high as possible to save electric energy.


6. Frequency conversion speed regulation
Most of the loads of fans and pumps are selected according to the demand for full-load work. In practical applications, most of the time is not in a full-load working state. Since it is difficult to adjust the speed of AC motors, windshields, return valves, or start and stop times are often used to adjust the air volume or flow. At the same time, it is difficult for large motors to frequently start and stop under the power frequency state, and the power shock is large, which will inevitably cause power loss and Current impact when switching on and off. It is the most scientific control method to directly control the load of fans and pumps with the frequency converter. When the motor runs at 80% of the rated speed, the energy saving efficiency is close to 40%. At the same time, closed-loop constant pressure control can also be realized, and the energy saving efficiency will be further improved. . Because the frequency converter can realize the soft stop and soft start of large motors, it avoids the voltage shock when starting, reduces the failure rate of the motor, prolongs the service life, and also reduces the capacity requirements and reactive power loss of the power grid.


7. Liquid speed regulation of winding motor
The liquid resistance speed control technology is developed on the basis of the traditional product liquid resistance starter. The purpose of stepless speed regulation is still achieved by changing the distance between the plates to adjust the size of the resistance. This makes it have good starting performance at the same time. It is powered on for a long time, which brings about the problem of heating and heating. Due to the unique structure and reasonable heat exchange system, its working temperature is limited to a reasonable temperature. The liquid resistance speed regulation technology for winding motors has been rapidly popularized due to its advantages of reliable operation, convenient installation, large energy saving, easy maintenance and low investment. For some speed regulation accuracy, the requirements for speed regulation are not high and the speed regulation range is not wide. , and infrequent speed regulation of wound motors, such as large and medium wound asynchronous motors of fans, pumps and other equipment, the use of liquid speed regulation effect is remarkable.
