摘要： Controllers for controlling hybrid motor drive circuits configured to drive a motor are provided herein. A controller is configured to drive the motor using an inverter when a motor commanded frequency is not within a predetermined range of line input power frequencies, and couple line input power to an output of the inverter using a first switch device when the motor commanded frequency is within the predetermined range of line input power frequencies.

摘要： An electric motor system is described. The electric motor system includes a drive circuit including an inverter configured to supply variable frequency current and a contactor configured to supply line frequency current. The electric motor system also includes an electric motor coupled to the drive circuit wherein the electric motor is communicatively coupled to a controller. The controller is configured to control the inverter to supply variable frequency current to the electric motor, thereby operating the electric motor at a motor speed, and determine, based upon at least one input parameter, a maximum potential motor speed the inverter can achieve. The controller is also configured to receive a command to operate the electric motor at line frequency current and control the drive circuit to transition from supplying variable frequency current to supplying line frequency current before the maximum potential motor speed the inverter can achieve is reached.

摘要： A motor includes a stator comprising windings configured to be energized, and a rotor electromagnetically coupled to the stator and configured to turn relative thereto when the stator is energized. The motor also includes a motor controller configured to measure a speed at which the rotor turns, and energize said stator to generate a first torque output at the rotor when the measured speed is below a first threshold. The motor controller is also configured to energize the stator to generate a second torque output at the rotor when the measured speed is at least the first threshold, wherein the second torque output is greater than the first torque output.
