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.

摘要： A motor control system or electronic motor starter is optimized to replace electromechanical motor starters. Heat dissipation requirements are reduced by utilizing a by-pass contactor when the motor is in a run mode. The electronic motor starter derives power from an AC motor control signal conventionally utilized to power the coritactor coil associated with a conventional electromechanical starter.

摘要： In a relay device, a first PTC thermistor has one end connected to a first external connecting terminal, and the other end connected to one end of a second PTC thermistor, the other end of which is connected to a second external connecting terminal, and the thermo-switch is thermally coupled to the first and second PTC thermistors, and connected in parallel with the second PTC thermistor. The thermo-switch is held closed when not heated, and is opened by heat generated by the first or second PTC thermistor. Therefore, the relay device is low in initial resistance, and small in power consumption during heat balance.

摘要： An autotransformer is used to replace the start capacitor in a split phase induction motor. The autotransformer windings are protected by a PTC resistor which also serves to effectively de-energize the auxiliary winding. In a preferred embodiment, efficiency of the motor in the run mode is enhanced by shunting the secondary of the autotransformer with an NTC element. In alternative embodiments a relay coil is placed in series with the auxiliary winding circuit to remove the PTC and the primary of the autotransformer from the circuit when the motor is in the run mode.
