A single-phase AC induction motor is a brushless motor designed with a single stator coil. ST offers state-of-art, rugged devices such as TRIACs, thyristors and AC switches, allowing motor speeds to be regulated in various ways, depending on the cost and performance requirements of the final application.
- Bi-directional drives
When a motor with a permanent phase-shift capacitor is used, the direction of rotation can be reversed by means of two AC switches connecting the phase-shift capacitor in series with either of the two stator windings.
- Phase-controlled drives
ST offers a cost effective variable speed drive for low power single phase induction using a triac and a microcontroller.
