Abstract: A permanent split capacitor (PSC) motor includes a stator defining an axis of rotation and a rotor disposed adjacent the stator. The stator includes a start winding, a capacitor electrically coupled in series with the start winding, a first plurality of windings, and a second plurality of windings. At least one winding of the first plurality of windings is energized in parallel with at least one winding of the second plurality of windings at a first voltage and in series with the at least one winding of the second plurality of windings at a second voltage. The first and second pluralities of windings are energized to produce a plurality of motor speeds. The rotor rotates relative to the stator about the axis of rotation at a selected one of the plurality of motor speeds induced at least partially by a magnetic output of the windings of the stator.

Abstract: 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.

Abstract: In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes at least one permanent magnet and a substantially cylindrical rotor core including an outer edge and an inner edge defining a central opening. The rotor core includes a radius R, at least one pole, and at least one radial aperture extending radially though the rotor core from the outer edge to a predetermined depth less than the radius. The at least one radial aperture is configured to receive the at least one permanent magnet. The rotor further includes at least one protrusion extending into the at least one radial aperture, the at least one protrusion positioned substantially along a bottom of the at least one radial aperture and configured to facilitate retention of the at least one permanent magnet within the at least one radial aperture.

Abstract: 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.
