The brushless motor is a motor body and driver, as well as a mechatronic product. What are the reasons for the high temperature when it is in use? The following is the compilation of the editor:
1. The power supply voltage is high, exceeding 10% of the rated voltage of the motor, causing iron loss and heating of the motor
2. The power supply voltage is too low, less than 5% of the rated voltage of the motor, and the brushless motor will generate heat when running at the rated load. The solution is to adjust the transformer tap switch level to adjust the power supply voltage to the normal range.
3. The three-phase power supply voltage is unbalanced, and the voltage unbalance between phases exceeds 5%, causing the three-phase current to be unbalanced and causing the motor to heat up.
4. Open circuit operation of brushless motor
5. If the load is heavier, the load should be reduced or a motor of suitable capacity should be replaced.
6. The brushless motor started too frequently.
7. The mechanical load is a malfunction.
