    摘要： A method for evaluating a permanent magnet motor, which includes a rotor with a plurality of magnets mounted thereon, and a stator with a plurality of windings in proximity to the rotor and coupled to an inverter, includes spinning the motor such that a voltage is induced in the windings of the stator and the inverter; measuring the voltage on the inverter; calculating the voltage constant from the motor from the measured voltage; comparing the voltage constant to accepted voltage constants; and identifying the motor as not acceptable if the voltage constant is outside of a range of the accepted voltage constants.

    摘要： A method evaluates a motor assembly having a first permanent magnet motor in a transmission of an automotive drive system at an end of manufacturing line evaluation. The first motor includes a first rotor with a first plurality of magnets mounted thereon, and a first stator with a first plurality of windings in proximity to the first rotor and coupled to a first inverter. The method includes spinning the first motor with an input dynamometer machine to a predetermined speed such that the first rotor of the first motor induces a first voltage on the first inverter; measuring the first voltage on the first inverter; calculating a first voltage constant of the first motor from the first voltage; comparing the first voltage constant to accepted voltage constants; and identifying the motor as not acceptable if the first voltage constant is outside of a range of the accepted voltage constants.

    摘要： A powertrain system includes a transmission operative to transfer power between a plurality of power actuators and an output member, and an energy storage device. A method for controlling the powertrain system includes establishing a first set of electric power limits and a second set of electric power limits for the energy storage device, determining a preferred input power from a first power actuator based upon the first set of electric power limits, determining a first set of power constraints for constraining input power from the first power actuator and a second set of power constraints for constraining output power from the output member based upon a second set of electric power limits, and controlling operation of the powertrain system based upon the preferred input power, the first set of power constraints, and the second set of power constraints.
