Related introduction

The vibration frequency range of CVM vibration motor is large, and the mechanical noise can be reduced only if the exciting force and power are matched properly. There are six types of vibration motor, such as starting and running mode, running speed and so on.

CVM vibration advantages:

1. If the exciting force and power match properly, the vibration force is large, the body weight is light, the volume is small, and the mechanical noise is low.

2. Because the vibration motor is a strong resistance vibration rather than resonance, it has a stable amplitude.

3. The vibration frequency range is large. The vibration frequency of the electromagnetic vibration exciter is fixed, which is generally equal to the power supply step rate, while the vibration frequency of the vibration motor can be adjusted in a wide range by adjusting the speed, and the vibration frequency and amplitude can be arbitrarily selected according to different paths.

4. Due to the fluctuation of power supply, the electromagnetic vibration exciter will change the exciting force greatly due to the voltage change, but this change is very small in the vibration motor.

5. Multi machine combination can realize self synchronization and complete different process requirements.

⒍ the direction of exciting force can be changed according to the installation mode of vibration motor.

⒎ the exciting force and amplitude can be adjusted steplessly only by adjusting the angle of eccentric block.

8. The maintenance is simple. Because the spring is not used like the electromagnetic type, the maintenance work such as clearance adjustment and weight adjustment can be avoided, and the bearing only needs regular maintenance.

Connection power supply of CVM vibration motor:

Since the outgoing cable of vibration motor is subject to vibration, heavy four core cable shall be selected. Sudden bending is not allowed near the cable outlet. A bending radius of 8-9 times of the cable outer diameter shall be provided, and then the cable shall be fixed to the stationary machine or frame. The distance is about 0.6 to 0.9 meters. Soft insulating material should be padded at the clip of fixed cable to avoid friction damage to the cable. One end of the grounding wire of the four core cable is connected with the grounding screw in the junction box, and the other end must be reliably grounded. Small type vibration motor, there is no junction box on the shell, using heavy three core cable directly from the motor internal wiring. The grounding screw is installed near the foot of the motor, which must be grounded reliably.

Troubleshooting of CVM vibration motor:

1. After starting up, the motor does not start. Check:

1) Whether the power supply lacks phase;

2) Whether the motor phase is broken;

3) Whether the protective cover is damaged and the eccentric block is abraded;

2. After starting up, the motor is noisy and hot. Check the following items:

1) Whether the roughness of contact surface between vibration machinery and motor foundation meets the installation requirements;

2) Whether the anchor screw bolt is tightened;

3) Whether the vibration acceleration of the main engine meets the use requirements;

3. After adjusting the eccentric block, the amplitude change is abnormal. Check whether the eccentric blocks at both ends of the shaft are adjusted symmetrically;

4. In the vibration equipment with two vibration motors working at the same time, when the phase transition does not meet the requirements, the phase sequence of the single vibration motor must be adjusted, and the phase sequence of the main power supply of the two vibration motors should not be adjusted.
