Small erm vibration motors are available in a wide range of sizes and shapes, from round to square, to suit a variety of applications. With their compact size and low weight, the small erm vibration motors are a great choice for your applications where space is limited. Miniature ERM Motors are used almost exclusively for vibration alerting and haptic feedback. Therefore, most of machines or applications that use sound or light to offer user/operator feedback could be achieved by a vibration motor.

The ERM (eccentric rotating mass) vibration motor is a type of linear vibration motor that uses a rotating mass to create vibration. The erm motor has an eccentric (offset) mass that is attached to the shaft. As the shaft rotates, the offset mass creates a centrifugal force that causes the shaft to vibrate. The size of the erm vibration motor will determine the amount of force it can generate, and the voltage will determine the speed at which the motor will rotate.

The linear resonant actuators are available in two specific form factors: coin and bar (with a few square designs). The linear vibration motor is used in a variety of applications where linear motion is required, such as vibrating massage chairs and cell phones. LRAs are also used in some automotive applications, such as active suspension systems.

Coin vibration motors, also known as shaftless or pancake vibrator motors, that are all Eccentric Rotating Mass (ERM) motors, generally in Ø6mm – Ø12mm diameters range. Due to their small size and enclosed vibration mechanism, coin vibrating motors are great for haptics, particularly in handheld instruments where space can be at a premium.

Cylindrical vibration motors are used in a wide variety of applications, including cell phones, pagers, vibrating pens, and medical devices. And also used in some industrial applications, such as vibrating sieves and conveyors.

Encapsulated vibration motor is typically used in medical devices or in industrial equipment. The encapsulated design helps to reduce noise and to protect the internal components from dust and other debris.

SMT vibration motors are typically small and compact, which makes them ideal for use in portable electronic devices.
