The reasons why the brushless motor can not work?

Brushless DC motors are more and more widely used. We often encounter problems that cannot be started when we use them. We follow the operating instructions, but why brushless motor can not work?

1. Power is missing
Possible situations: For example, the power switch is not closed properly, the front-level fuse is blown, the fuse of the main circuit or control circuit of the motor is blown, the power control device such as the contactor fails, and the wire is broken or loose. The solution is to start with the front-level fuse and gradually check the wires and components of the main circuit and control circuit of the motor, find the cause and repair it.
2. Motor issue
Possible situations: power supply voltage is insufficient or poor contact, the control circuit of the brushless DC motor controller is not connected or connected less, the motor Hall sensor is damaged, the motor coil insulation is reduced and the motor is burned, the motor rotor magnet loses magnetization, and the motor load is far Exceeding its own load torque, the power supply voltage is too high or unstable
3. Mechanical failure
The mechanical equipment or transmission mechanism of the motor is stuck, and the starting load is too heavy. At this time, the power supply should be cut off quickly to find mechanical failure.
The above are the reasons why the brushless DC motor cannot work. please check the above problems before use. If motor still can’t work after the inspection, then don’t repair it by yourself. Please find a professional technician to repair it to prevent improper repair and cause more damage.
