Adjustment method for too small exciting force of vibration motor (Part 2)

3. Connect the power supply

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 to ensure reliable grounding when using.

Attention: the outgoing cable of vibration motor is a vulnerable part, which often leads to phase loss operation and damage of motor due to vibration and friction damage. The user should check the condition of the cable frequently, and replace the cable of the same type in time in case of abrasion.

Try to add lubricating oil every 3 months, if the service time is too long (add as appropriate)

Importance of vibration motor maintenance

Vibration motor has been widely used in vibration machinery, that is, the purpose of vibration motor covers hundreds of industries, such as mining, chemical industry, pharmaceutical, etc. in various industries, the working environment of vibration motor is different, so the daily maintenance of vibration motor is not the same. Therefore, we should often observe the static and dynamic state of the vibration motor, and solve the problems in time to avoid unnecessary damage, which will affect the work and unnecessary waste.

Static observation: before each operation of the equipment, small vertical head should be used to knock the foundation screw of vibration motor for looseness, which can be judged by visual inspection and upright knocking sound. If there is looseness, the reaction force of the vibration motor will be uneven during operation, which is easy to cause the motor to tear and burn.

Dynamic observation is to listen to the sound of vibration motor during its operation. If the sound is abnormal, it is necessary to stop the machine for inspection. If the temperature of the motor is too high, the vibration of the motor will be damaged if the temperature of the motor is too high.
