A vibration motor is a type of electric motor that is specifically designed to generate vibrations. It consists of a rotor, an eccentric weight, and a set of magnets. The magnets play a crucial role in the operation of the vibration motor as they are responsible for creating the magnetic field that interacts with the electric current to produce the desired vibrations.

The magnets used in vibration motors are typically permanent magnets, which means they retain their magnetism even when not in the presence of an external magnetic field. Permanent magnets are commonly made from materials such as neodymium iron boron (NdFeB) or samarium cobalt (SmCo). These materials have high magnetic strength and can generate strong magnetic fields.
The magnets in a vibration motor are arranged in a specific configuration to create a rotating magnetic field. This rotating magnetic field interacts with the electric current flowing through the motor’s coils, causing the rotor to rotate. The eccentric weight attached to the rotor creates an imbalance, resulting in vibrations.
Our coin or pancake vibrating motors are all Eccentric Rotating Mass (ERM) motors. Therefore they can be driven in the same manner as their pager motor counterparts. They have the same motor drive principles, including H-bridge circuitry for active braking.
