ABSTRACT:
A control circuit for an electric motor having start, low speed and high speed windings reactivates the start winding at different reduced motor speeds depending upon whether the motor is running on the low speed winding or the high speed winding. Reactivation of the start winding while the motor is running on the low speed winding automatically deactivates the low speed winding and activates the high speed winding.
