How do I choose the right vibrator motor for a screen or feeder?

Confirm four things before selecting a motor: structure mass, target amplitude, operating frequency and mounting stiffness. These decide the required force (kN) and whether a 4-pole (1440 RPM) or 6-pole (960 RPM) motor fits.

What is the difference between 4-pole and 6-pole vibrator motors?

A 4-pole motor runs at about 1440 RPM, giving a higher excitation frequency. A 6-pole motor runs at about 960 RPM, giving a lower excitation frequency.

What force range does the Bhajjanka DYNASHAKE series cover?

The DYNASHAKE range covers 30 to 72 kN across five models: MV3000/15, MV5500/15, MV7200/15, MV4700/1 and MV5500/1, all with IP 66 enclosure, Class F insulation and S1 continuous duty.

What warranty do Bhajjanka vibrator motors have?

The motors carry a guarantee of 1 year from the bill of lading (BL).

Electric Vibrator Motors: How to Choose the Right One for Your Screen or Feeder

Q: What is an electric vibrator motor?

An electric vibrator motor is a three-phase motor with eccentric weights on both shaft ends. When the shaft rotates, the weights create centrifugal force that makes the screen, feeder or hopper it is mounted on vibrate.

When material stops, production stops

In crushing, mining and material-handling plants, a jammed hopper or a sluggish feeder means lost output. The part that keeps material moving is often small compared to the plant, but it matters: the electric vibrator motor.

What is an electric vibrator motor?

It is a three-phase motor with eccentric weights fitted on both ends of its shaft. When the shaft rotates, these weights create centrifugal force. Bolted onto a screen, feeder or hopper, that force makes the whole structure vibrate. The vibration moves material forward, separates it by size or stops it from sticking.

The 4 things to check before choosing

Force (kN): It must suit the mass of the structure and the load it carries. Too little force and the material will not move properly.
Speed and poles: A 4-pole motor runs at about 1440 RPM, which means higher frequency. A 6-pole motor runs at about 960 RPM, which means lower frequency. Your target amplitude and operating frequency decide which band fits.
Mounting stiffness: The motor needs a rigid base. A weak mounting wastes force and can damage the structure.
Duty and protection: Plants run for long hours in dust and moisture, so continuous-duty rating and a high IP rating are essential.

Selection check

Before finalising a motor, confirm four things: structure mass, target amplitude, operating frequency and mounting stiffness. The SIMLABS team can help verify your application before you order.
