2021 All New 12V DC Vibration Motor

There are usually two types of vibration motors that are widely used, one is ERM type and the other is LRA type. Both of them can be provided by NFP-Motor. Generally, if need a strong vibration force the erm type is used, and it is not quite precise when compared with LRA type.

However it can provide a strong enough vibration amplitude. The miniature vibration motors can be used for indicators, when the warning occurs, timely provide vibration feedback alerting, so that the followers get a reminder. Usually erm type miniature vibration motors is cheaper. The ERM vibration motors is made of carbon brush type micro dc motor with an eccentric rotating mass on its shaft.

The vibration force or amplitude is usually depended on the rotation speed of the motor and the size of the eccentric rotating mass. For example, the radius and length of the eccentric rotating mass are proportional to each other. The higher the rotation speed, the stronger the vibration force, the larger the eccentric wheel size, the stronger the vibration amplitude.

Another should be considered is the Voltage. This motor can be fitted with a rubber sleeve to form a waterproof type vibration motor, it’s sealed to meet the needs of different scenes.
