3 Types Coin Vibration Motors – Compact Size, Easy To Integrate


BLDC Brushless coin vibration motors are the excellent choice for high reliability applications that is requiring a quite 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. NFP offers 3 dimensions BLDC coin vibration motors typically exceed the life time of brushed type coin motor by over 10 times.

These 3 types coin vibration motors are more costly than brushed types for they are inside a driver IC. “+” and “-“polarity must be observed very carefully when apply power. Other specs are comparable to those of standard brushed type erm coin vibration motors. Custom lead wire lengths and connectors(eg Molex, JST…) are available for MOQ: 1+ pc.

The smallest coin vibration motor BLDC brushless type only 6mm diameter in the market. Its low G force will limit its applications to very light weight wearables such as smart rings and light weight watches and other wearable devices etc. Double stick tape on the bottom of the case facilitates mounting.

3 Diameters Iron Core Brushless Vibration Motor


NFP-Motor recently released three diameters brushless vibration motors of cylindrical type, including Φ24mm, Φ22mm, Φ16mm series. The brushless vibrating motors are all ERM types, that means the vibration principle is same as other brush type eccentric rotating mass vibration motors. However the BLDC vibration motor’s lifetime is significantly improved(≈2,000 hours).

Why the brushless vibrating motors have such long working time? For their inside structure have been changed, the precious metal brushes with commutator is removed. To check all differences you can see the below table.

BLDC – Brushless DC vibration motors


Mini brushless DC vibration motor BLDC Brushless coin vibration motors are an excellent choice for high reliability applications requiring an exceptionally long life time (usually 1 million cycles lifetime) / 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 expensive than brushed types ERMs since they incorporate a driver IC. Polarity must be observed when apply power. 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: 5K pcs plus applicable tooling fees.

Still Can’t Find Ideal Motors?


The electrical parameters of the motor can be adjusted. For example, the two main factors determining the vibration force: the size of the pager motor eccentric mass and the speed requirement. , voltage, current can be adjusted according to customer needs. Some encapsulated vibration motors adding terminals connectors, which are our customized products according to different customers. You can also contact us in the bottom contact form to ask for your needs.

If you want a custom lead wire connection of the  water resistant vibration motors. Such as alternate lead wire length & strip lengths, with a connector (e.g. Molex, JST). You can contact us from the footer form, tell us your need. Any problems will be taken seriously and will be answered professionally, so pls do not hesitate to contact us by the footer form.
