Abstract:
1. A motor starting device for a single-phase split-capacitor induction motor connected to a source of alternating current voltage, the motor having a run winding, a start winding, and a start capacitor, the starting device comprising: a. an auxiliary start capacitor; b. a switching device comprising: c. a bridge rectifier connected through the motor windings to the source of alternating current voltage for producing a source of direct current voltage when the source of alternating current voltage is connected to the motor; d. a control circuit connected to the source of direct current voltage and connected to the switch activation circuit for selectively energizing and deenergizing the switch activation circuit; and e. a self-protecting switch protection rectifier circuit connected to the auxiliary start capacitor for maintaining the source of direct current voltage connected to the control circuit when the source of alternating current voltage is disconnected from the motor.
