Vibration Motors: Applications, Advantages and Installation Precautions

A vibration motor (also called an oscillating motor) is an excitation source that combines the power source and the oscillating source in one unit. Adjustable eccentric blocks are mounted at each end of the rotor shaft; as the shaft spins at high speed, the centrifugal force generated by the shaft and eccentric blocks produces the exciting force that drives the equipment.

Why Choose a Vibration Motor?

Vibration motors offer a high utilization rate of exciting force, low energy consumption, low noise and long service life. The exciting force can be adjusted steplessly, which makes them convenient to set up and tune. Common models such as XJD, JZO, YZU, VB, XVM, YZO, YZS, YZD, TZD and TZDC are general-purpose units suitable for almost any oscillating machinery.

Typical Applications

Vibration motors are used across a wide range of industries — hydropower construction, thermal power generation, construction, building materials, chemical processing, mining, coal, metallurgy and light industry. Typical machines include:

• Oscillating crushers and screening machines
• Oscillating packers, molding machines and shakeout machines
• Oscillating pile drivers, elevators and fillers
• Arch-breaking and anti-blocking equipment for silos

Installation Precautions on Oscillating Equipment

YZS vibration motors are a very common power source on linear shale shakers. When installing one, watch for these common problems:

1. Winding insulation: if the winding has absorbed moisture, test insulation resistance with a 500 V megger. Near operating temperature (70 °C) it should be at least 0.38 MΩ; otherwise the winding must be air dried.
2. Cables: check that the motor cable is intact. Replace any broken or damaged cable immediately.
3. Motor body: inspect the housing for damage and arrange replacement if any is found.
4. Anchor bolts: tighten the mounting bolts fully and fit a ductile sealing ring under each nut.
5. Run-in re-tightening: in early operation, the bolts, nuts and base settle and lose clamping force. Re-tighten daily at first, then weekly after about half a month.
6. Cable slack: leave a naturally suspended loop of 300–500 mm between the clamp on the body and the fixed clamp, roughly forming a half arc, so vibration is not transferred into the cable.

The same principles — balanced rotating parts, controlled vibration and correct mounting — apply to the motors we build for light electric vehicles as well. If your project involves electric drivetrains, see our electric motorcycle motors and moped and scooter motors.
