BLDC – Brushless DC Coin Vibration Motors |
![]() |
BLDC (Brushless DC) coin vibration motors are an excellent choice for high reliability applications requiring an exceptionally long life time / MTBF. Applications where the vibration feature used very often or is used in a medical device should consider a BLDC vibrator motor. These BLDC motors typically exceed the life time of brushed type coin motor by over 10 times. They are more costly than brushed types since they incorporate a driver IC. Polarity must be observed when apply power. The motors operate on DC voltage only. A PWM signal can not be used to drive BLDC motors. Due to slow rise / fall time these are not the best choice for haptic feedback and are best suited for application where simple notification alerts are desired. These motors are controlled by an integrated circuit (IC), which uses sensors to detect the position of the rotor’s north and south poles. Since there are no brushes in contact with the rotor during startup, friction is minimized. To further reduce operational noise, lubricating oil is applied to the bearings. If a motor is stored for longer than approximately eight months, this oil may dry out or solidify. Because BLDC motors generate relatively low magnetic force, dried lubrication can cause excessive friction, resulting in startup failure due to insufficient torque. In such cases, gently tapping the device or motor can help initiate movement. Once the motor starts running, the oil typically re-liquefies, resolving the issue permanently. Based on customer feedback, these motors can generally still function normally even after around 12 months of storage. We are actively working on further improvements and optimizations to enhance performance and reliability. Other specs are comparable to that of standard brushed type motors. Custom lead lengths and connectors are available for MOQ: 1K pcs. Custom FPC’s are available for MOQ: 6K pcs plus applicable tooling fees.
