During operation, vibration phenomena will occur in the vibration motor. However, if the vibration is too large, it will damage the bearings, rotor and other components of the vibration motor. What is the vibration of a vibration motor? How should we solve it?

The vibration of the vibration motor caused by the vibration of the vibration motor base may be due to the excitation force generated by the vibration of the rotor or the electromagnetic vibration produced by the stator core. The specific vibration reduction measures to minimize the vibration of the motor frame are as follows: 1) Set up an elastic structure, that is, change the connection structure between the core and the base to an elastic structure to reduce the impact of vibration. To a certain extent, 2) Control the natural frequency of the base itself to avoid frequency doubling of the core. Vibration frequency and rotor vibration frequency.

Four Causes and Countermeasures of Vibration Motor vibration

Rotor imbalance can cause the vibration of the vibration motor. The treatment methods for vibration caused by rotor imbalance are as follows: 1) The basic principle of dynamic balance inspection is adopted for treatment, that is, the vibration phenomenon caused by the centrifugal force generated by the unbalanced mass when the rotor rotates. Discovered. Eliminate the specific position and size of the rotor imbalance, and then eliminate it by weighting or reducing the weight. 2) For the vibration caused by the rotor mass, it is necessary to conduct static balance and low-speed dynamic balance tests of the rotor in advance. During the operation of the vibration motor, as needed, high-speed dynamic balance tests of the rotor can be conducted by using vibration measurement balance, thereby eliminating the mass imbalance factors of the rotor as much as possible.

The vibration motor bearings make the vibration motor vibrate. During operation, the force acting on the bearing can cause two different types of vibration: one is the relative vibration between the bearing housing and the rotor, and the other is the vibration of the bearing housing itself.

The stator winding can cause the motor to vibrate. When the vibration motor is in operation, the stator winding is usually affected by some forces, which can cause the system frequency or the winding frequency to vibrate. When designing vibration motors, technicians often need to take electromagnetic force into consideration. The grooves and top of the stator winding vibrate. To avoid vibration in the grooves and at the top, a wire fastening structure with grooves or an axial rigid support at the end can be adopted to reduce vibration.

Based on the above analysis, we must promptly check the causes of the vibration of the vibration motor during daily use to prevent further damage to the vibration motor.
