20 Kinds Coin Vibration Motor List

Coin vibration motor, generally in Ø6mm – Ø14mm diameters. Has the small size and easy to use. Phone vibration motor is a popular choice for many different applications. Coin vibration motors are great for haptics.

SmartPhone Vibration Motors

Coin vibration motors are the most popular and cost effective haptic motor, super small dimensions and enclosed vibrating mechanism with no eccentric exposed . This kind of eccentric motors are widely used in mobile phones and wearable devices, it is available in diameter ranging from Ø6mm to Ø14mm.

Custom Design Pancake Vibration Motors

Enclosures can easily be moulded to accept the coin form of our shaftless vibration motors. Within the coin motor range, we offer both leaded and spring & pad mountable versions. Like all of our vibration motors, we are happy to quote for variations to the base design such as a modification to the lead length and also connectors. Custom design with or without foam pads & adhesive on the top or bottom of the coin motors. It was designed for wearable devices that requires vibration feedback for alerting instead of physical buttons.

How erm motor works? There is an eccentric wheel on the motor shaft. When the motor rotates, the center mass point of the eccentric wheel is not on the rotation center of the motor, so that the motor is constantly out of balance, causing vibration due to inertia.

Three kinds of coin vibration motors – LRA – linear resonant actuator(fast rising and brake time), BLDC – brushless DC coin motor(long lifetime), ERM – eccentric rotating mass. Generally we talk about coin vibration motors, also called as shaftless, pancake, disc vibrator motors, is to say the ERM type. For it’s widely used in advanced wearable devices, smart watches. It can be made as either FPC contract or wire leads types.

Comparing with other ERMs(pager motors), coin vibration motor are more compact and convenient to use, particularly in handheld instruments where space should be carefully considered. Unlike cylindrical vibration motor, eccentric rotating mass of coin motor is located inside the case shell, which will significantly reduces the thickness and provide a stronger closure to the motor.

Typical applications: Vibrating Bracelet, Handle Scanner, vibrating table motor, vibrating pager motor, vibrating motor radio shack, vibrating cell phone motor, furnace motor vibrating, toothbrush vibrating motor…
