摘要： A motor starter system comprises solid state switches for connection to an AC line for controlling application of AC power to the motor. A fault contactor has contacts. A motor wiring circuit operatively connects the solid state switches and fault contactor contacts with motor winding terminals. A voltage sensor senses AC line voltage and motor terminal voltage.

摘要： A motor controller for a motor operated by an AC line voltage includes solid-state switches connectable between an AC line and a motor terminal for controlling application of AC line voltage to the motor. A current sensor senses motor current. A control circuit is connected to the switches and the current sensor for varying relative duration of on time and off time during each cycle of line voltage to control motor voltage. The control circuit determines on time during each cycle of line voltage and compensates sensed motor current responsive to the sensed on time.
