12MM BRUSHLESS DC VIBRATION MOTOR – 15MM TYPE MODEL NFP-1215
Brushless vibrating motors overcome these issues discussed above by using stationary coils called a stator (as opposed to an armature). Instead of the magnet staying put (as in brushed motors), in the brushless vibration motor- NFP-1215, the magnet is attached to the shaft and therefore rotates.
These brushless vibration motors tend to be more efficient, but the major benefit is the extended life-time. This means they are popular in products that require prolonged or constant rotation. In the past DC brushless motors have been used devices such as VCRs, printers and hard disk drives.
