How is Amplitude Generated?

For the common eccentric weight (rotating mass) vibration motor, the amplitude A is primarily determined by the following relationship:

A ≈ (M × e) / m

Where:

M: Total mass of the eccentric weights (kg)

e: Eccentricity (m) - the distance from the center of mass of the weights to the axis of rotation.

m: Total vibrating mass of the system, including the machine structure, material load, and the motor itself (kg).

A: Resulting Amplitude (m)

This is the principle of amplitude adjustment:

Adjusting the Eccentric Weights: By changing the relative angle between the two adjustable eccentric weights on the motor shaft, you change the effective M × e (the centrifugal force moment or exciting force). When the weights are aligned, force is maximal, leading to maximum amplitude. When offset, forces partially cancel, reducing amplitude.

Effect of Vibrating Mass: The material load (m) on the machine directly affects amplitude. Amplitude is highest when empty and decreases under load. Design and setup must account for this.
