Linear Vibration Motor Introduction | Baolong Electronic

What Is Linear Vibration Motor. There are two basic types of vibration motor. An eccentric rotating mass vibration motor (ERM) uses a small unbalanced mass (we usually call it eccentric weight) on a DC motor, when it turns it creates a centrifugal force that translates to vibrations. A linear vibration motor contains a moving mass attached to a wave spring, which creates a force when driven.

An Analytical Approach to Solving Motor Vibration Problems

On 2 pole motors, the twice line frequency vibration level will appear to modulate over time due to it's close relationship with 2 times rotational vibration. Problems in a motor such as a rub, loose parts, a bent shaft extension or elliptical bearing journals can cause vibration at 2 times rotational frequency.

Engine balance - Wikipedia

For example, in order for a piston in a single cylinder engine to be accelerated upward, something must receive (support) the downward force, and it is usually the mass of the entire engine that moves downward a bit as there is no counter-moving piston. This means one cause of engine vibration usually appears in two opposing directions.

to examine that order and to ignore the other orders. When you measure one order and exclude the others, the measurement is called an order track. Figure 4 shows this 12th order amplitude versus RPM for the engine run-up. In the order track measurement, the relationship between the measured order vibration and the engine speed is clear.
