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： 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.

摘要： 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.

摘要： A permanent magnet rotor core includes a plurality of rotor poles circumferentially-spaced about a central axis and including a first rotor pole and an adjacent second rotor pole that each include an outer wall, and wherein the rotor core includes a rotor diameter. The rotor core also includes a plurality of radial apertures alternately-spaced with the plurality of rotor poles. The rotor core also includes a first protrusion extending from the first rotor pole into a first radial aperture of the plurality of radial apertures positioned between the first rotor pole and the second rotor pole. The rotor core further includes a second protrusion extending from the second rotor pole into the first radial aperture such that a circumferential opening is defined between the first protrusion and the second protrusion. The opening extends a first length of between approximately 0.052% and approximately 0.058% of the rotor diameter.

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 variably frequency current to supplying line frequency current before the maximum potential motor speed the inverter can achieve is reached.

摘要： A motor controller for controlling an electric motor includes at least one integrated sensor disposed on the electric motor. The least one integrated sensor is configured to collect sensor data associated with a status of the electric motor for a period of time, the period of time beginning at an activation time and extending at least until an installation time. The motor controller may include an energy management system configured to power the at least one integrated sensor for at least a portion of the period of time, and a memory device configured to store the sensor data. The motor controller may include a data management system configured to communicate the sensor data from the at least one integrated sensor to at least one of the memory device and a remote device.
