摘要: An alternating current (AC) motor system and control methods are provided herein. The AC motor system includes a motor having a first rated horsepower and configured to be coupled to a power source, and a drive circuit configured to be electrically coupled between the power source and the motor. The drive circuit has a second rated horsepower that is lower than the first rated horsepower.

摘要: A method of operating a drive circuit for parallel electric motors is provided. The method includes receiving measurements of stator phase currents in the parallel electric motors. The method includes selecting a target PM motor, from among the parallel electric motors, that generates a largest torque output. The method includes executing a vector control algorithm to generate a complex command voltage vector for the target PM motor. The method includes generating and transmitting a pulse width modulation (PWM) signal based on the complex command voltage vector for controlling an inverter. The method includes operating the inverter according to the PWM signal to supply three-phase alternating current (AC) power to the parallel electric motors.

摘要: Motor controllers and methods for controlling drive circuit bypass signals are provided. The motor controller includes a drive circuit configured to generate variable frequency power based on input power received from a power source, and a drive contactor coupled between an output of the drive circuit and the motor. The drive contactor is configured to couple the drive circuit to the motor when a drive enable signal is received from an external controller, and decouple a line power enable signal from a line contactor by the external controller based on a presence of the drive enable signal. The line contactor is configured to couple the motor directly to the power source when the line power enable signal is received by the line contactor.
