摘要： A system in which the operation of an electric motor is controlled by electronically controlled switches. The system includes the motor having a run winding and a start winding, a heating component, and a motor control subsystem. A control unit closes a first switch to energize the run winding, closes a second switch to energize the start winding, determines based on an amplitude and a lag time of a current flowing through the motor whether the motor has started and is running normally, and if so, opens the second switch to de-energize the start winding and closes a third switch to activate the heating component. The control unit determines whether the motor has started and is running normally by comparing the real time amplitude and lag time of the current to a plurality of stored amplitudes and lag times associated with different operating conditions.

摘要： Included herein is a circuit comprising resistors, capacitors, relays, diode bridges, TRIACs, and DIACs mounted to a substrate. The circuit may be electrically connected to a user device containing a wide range of types and specifications of AC induction motors. The circuit may be installed “plug-and-play” onto a user device, without the need for tools, custom installation or deconstruction of a user device. Upon user direction or automatically, the circuit may inject DC current into the user tool which generates a stationary magnetic field inside the AC induction motor causing deceleration/arrestment of the AC induction motor's rotor. The circuit may prevent unintended acceleration of the rotor upon powering on the user device. Also included is a method for prevention of unintended acceleration of the rotor upon powering on the user device. Also included is a method for decelerating/arresting an AC induction motor.

摘要： A compressor for commercial refrigerators comprises an electric motor having a start winding (120) and a run winding (130), in which the input terminals of the start winding (120) and the run winding (130) are connected together and to the line voltage (L), and an electronic start device to supply the start winding (120) during a starting period. The electronic start device comprises a run condenser (40) having a first terminal connected to the output terminal from the start winding (120) and a second terminal connected to the output terminal from the run winding (130), and a start capacitor (45) having a first terminal connected to the output terminal of the start winding (120). In the electronic start device there is also provided a solid state switch (110) which supplies the start winding (120) and is connected between the second terminal of the start capacitor (45) and the neutral terminal of the supply (N), and a control circuit (100) comprising a delay circuit (210, 220) which controls switching of the solid state switch (110) closing it to start the motor and opening it at the end of the starting period once the motor has started.

摘要： A hard start capacitor replacement unit has a plurality of capacitors in a container sized to fit in existing hard start capacitor space. The capacitors are 4 metallized film capacitors wound in a single cylindrical capacitive element. The container has a common terminal and capacitors value terminals for the plurality of capacitors, which may be connected singly or in combination to provide a selected capacitance. An electronic or other relay connects the selected capacitance in parallel with a motor run capacitor. The hard start capacitor replacement unit is thereby adapted to replace a wide variety of hard start capacitors.
