ABSTRACT:
A circuit for providing dual speed operation of a single phase alternating current motor having high speed main and starting windings and a low speed main winding. A selectively energizable energizing circuit for the high speed main winding includes a current relay responsive to current flow through the high speed main winding for completing an energizing circuit for the high speed starting winding and a selectively energizable energizing circuit for the low speed main winding includes a bidirectional current translating device and a second current relay responsive to the flow of current through the low speed winding to complete the high speed main winding energizing circuit. The bidirectional current translating device is responsive to electrical control signals which are inhibited while the speed of the motor is greater than a predetermined value.
