The HD-EMC1003-2-LW15-R is a coin-style eccentric rotating mass (ERM) vibration motor designed for 3.0 VDC operation. Featuring 15 mm lead wires and pre-applied double-sided adhesive tape, it allows fast and flexible integration into wearables, handheld electronics, controllers, and portable medical devices.
With a rated speed of 13,000 ± 3,000 RPM and mechanical noise levels kept below 50 dBA, this motor is an excellent choice where compact size, reliability, and quiet operation are critical.
