July 17, 2012 - Precision Microdrives released 912-101 brushless vibration motor in a cylindrical form factor. Brushless vibration motors have a significantly improved lifetime over the commonplace ‘brushed’ vibration motor counterparts. This is because their internal construction removes the main source of failure - the precious metal brushes wearing against the commutator. The 912-101 brushless vibrating motor produces vibrations in the same way as other eccentric rotating mass vibration motors and therefore many of the design considerations, such as mechanical mounting, are similar. It uses a low supply voltage and has a small size, but has a comparatively high vibration amplitude.
This makes them ideal for use in heavy-duty applications that require frequent or sustained vibrations over long periods of time. Examples include aiding the flow of materials through a chute, agitating liquids and emulsifiers, or helping sort pills / components on a production line. In general, the mechanical aid field demands high usage rates with minimal services, and brushless vibration motors suit these requirements perfectly. Powered from only 5V, the 912-101 can achieve 30 G in vibration strength. At only 12 mm diameter and 15 mm in length, this is roughly double the strength of previous similar sized ERMs.
