The vibration motor is also a fragile device. When the operation is not accurate, not only the life of the motor itself is shortened, but also the vibration motor causes great damage to the mechanical equipment being dragged. Therefore, when using the vibration motor, it is necessary to strictly follow the application of the vibration motor. Increase the number of inspections and inspection intensity, and real-time treatment after finding hidden dangers, the vibration motor cannot keep moving.

The output cable of the vibration motor is subjected to vibration.

The output cable of the vibration motor is subjected to vibration. The bearings of the vibration motor should use heavy-duty bearings, which can bear the necessary axial load. Regardless of the deviation of the device, the bearing life is not affected by the axial load. The vibration motor should be recorded when disassembling the bearing. The location of partial pain block and the percentage of exciting force. After replacing the vibration motor, the motor shaft is unavoidable during axial movement. The vibration motor has no air test piece before operation. Record the reset of the pain mass.

The torque of a vibrating motor is generated by the interaction of magnetic flux and current.

The torque of a vibrating motor is generated by the interaction of magnetic flux and current. The torque of the vibration motor is proportional to the square of the voltage. The vibration motor changes the speed by changing the excitation current in the electromagnetic slip clutch. When the vibration motor is controlled by speed, an auxiliary control device is required, and the vibration motor is wound on the rotor asynchronous vibration motor. Since the rotor circuit is led to the outside through the slip ring, it is easy to realize the speed control.
