Why does the DC vibration motor make noise?

The brushless DC vibration motor is a new type of vibration drive device that uses the eccentric blocks installed at both ends of the rotor of a special dual-shaft three-phase asynchronous motor to provide vibration force. It is widely used as the excitation source of various vibrating machinery (such as vibrating feeder, vibrating conveyor, vibrating screener, vibrating shakeout, vibrating crusher, vibrating hoist, vibrating test bench, etc.) Used as a warehouse wall vibrator (silo wall rapper).

Compared with other vibrators (such as electromagnetic vibrators and warehouse wall vibrators), brushless DC vibration motors have the advantages of small size, light weight, simple structure, convenient disassembly and assembly, large excitation force, low power, high efficiency and low noise. , High power factor, vibration force can be stepless adjustment and so on. Because of its convenient use and simple structure, micro vibration motors are widely used in mining, metallurgy, coal, building materials, chemical industry, light industry, electronics, machinery, food and other industries.

Reason:

• A wound inside the bearing.
• The axial direction of the bearing is abnormally vibrated, and the gas spring constant in the axial direction and the rotor mass constitute the excitation of the vibration system.
• Friction noise: The cause of poor lubrication and bearing clearance of cylindrical rolling bearings or large-diameter high-speed ball bearings.
  

Solution:

• Replacement of bearings.
• Appropriate axial direction gas spring preload to change the bearing clearance.
• Select a soft grease or a grease with excellent low temperature properties, with a small residual gap (be careful about temperature rise).

How to use DC vibration motor?

When working on the DC vibrators, they must be safely disconnected from the electrical mains. Proceed as follows:

1. Switch off vibration motor.
2. Secure against unintentional switching on.
3. Determine that the NEA and NEG are voltage-free.
4. Earth and short-circuit.
5. Cover and fence off neighboring live parts.

The DC vibrators must not be touched during operation or shortly after being switched off. The surface temperature of the vibrators can reach such high values during operation that there is a risk of burning.
