摘要： An interior permanent magnet machine includes a rotor having a plurality of slots. First and second slots are disposed in a first pole and the third and fourth slots are disposed in a second pole. A first barrier is defined by the first, second, third and fourth slots. The slots are configured to be symmetric relative to their respective pole axes. A first angle is defined between the first and second slots. A second angle is defined between the third and fourth slots. The first angle is configured to be sufficiently different from the second angle so that torque ripple is minimized. Thus the rotor is configured such that the angular configuration of slots in a first pole is different from the angular configuration of slots in a second pole of the rotor.

摘要： In general, the various embodiments are directed to a permanent magnet machine (“PM machine”), and more specifically an internal permanent magnet machine (“IPM machine”) that includes rotor magnets configured asymmetrically with respect to the rotor periphery, thereby producing an averaging effect similar to that achieved through traditional skewing of the rotor magnets. In alternate embodiments, the span, placement and/or shape of the magnets may vary from one pole to the next.

摘要： A powertrain includes a first electric motor, a second electric motor and a transmission. The first electric motor includes an interchangeable winding set to provide the required power for the specific propulsion configuration utilized to propel the vehicle, i.e., a hybrid propulsion configuration or a full electric propulsion configuration. The transmission is operable in different powerflows to support operation of the powertrain in either of the hybrid propulsion configuration or the full electric propulsion configuration. The same powertrain may be used for either the hybrid propulsion configuration or the full electric propulsion configuration by switching the specific winding set installed into the first electric motor.

摘要： A conductor is provided for an electric machine having an axis, a radial direction extending outward from the axis, and a tangential direction perpendicular to the radial direction. The conductor includes a solid core, having radial faces substantially perpendicular to the radial direction of the electric machine and tangential faces substantially perpendicular to the tangential direction of the electric machine. At least one tangential depression is formed on at least one of the tangential faces. The tangential depression creates a tangential void within a rectangular envelope defined by the solid core. Therefore, the surface area of the solid core is greater than the surface area of the rectangular envelope.

摘要： A vehicle includes a motor, an alternating current (AC) power bus, a power inverter module (PIM), and a controller. The PIM includes a semiconductor die assembly with semiconductor power switches arranged in electrical parallel for delivering AC power to the motor via the bus. The controller determines an operating mode of the vehicle, selects and activates a designated one of the switches during a threshold low-current state of the PIM, and selects and activates all of the switches during a high-current state of the PIM. A PIM assembly for the vehicle includes the die assembly and controller. A method for optimizing energy efficiency of the vehicle includes providing the die assembly noted above, automatically determining the operating mode, and selecting and activating one of the switches when the operating mode corresponds to the threshold low-current state, and all of the electrical switches during the threshold high-current state of the PIM.

摘要： A hybrid powertrain is provided that includes an engine operatively connected with an input member. The powertrain includes a transmission with first and second electric motor/generators, a differential gear set having multiple members, and selectively engageable torque-transmitting mechanisms. The input member, the output member, the engine and the motor/generators are selectively interconnected through the differential gear set by engagement of the torque-transmitting mechanisms in different combinations. The powertrain provides multiple operating modes between the input member and the output member, including an electric-only operating mode in which the engine is off and both electric motor/generators act as motors to provide torque at the output member.
