What's with the motor buzzing? What is the reason for the motor buzzing?

1. If there is a problem with the connection of the power cord of the motor, resulting in single-phase operation, the motor will only make noise and will not rotate. At this time, it is necessary to check the power cord of the motor. If it is damaged, it needs to be repaired or replaced in time.

2. It is possible that the bearing capacity of the motor exceeds the range it can bear, which will also lead to the motor not acting, but there will be a buzz. In this case, just unload the motor and let it run at no load or half load.

If the mechanical part of the motor gets stuck, there will be noise. Reasons include motor oil shortage, bearing rust or serious bearing damage. At this time, it is necessary to stop using the motor, then check the mechanical position of the motor to see what caused the damage, and then repair or replace it in time.

4. If the wound motor is used, the rotor circuit will be open or disconnected, and this kind of fault will also occur. It is necessary to check the combination of the brush, slip ring or contactor of the motor in time, and maintain it in time to ensure its use.

5. If the internal terminal of the motor is wrongly connected, or it is disconnected or short-circuited, it will also enjoy buzzing and cannot be used. At this time, it is necessary to judge the head end and tail end of the three phases again, and check whether there is a short circuit or an open circuit, repair it in time, and then start using it to avoid the danger of details.
