Abstract: A system and method for facilitating regenerative charging of a battery by a motor drive when the battery is properly physically connected to a drive circuitry and blocking current when the battery is improperly physically connected. The system includes drive circuitry, a battery and motor drive connected to the drive circuitry, an N-channel MOSFET connected to a high side of the drive circuitry, and a FET controller including a charge pump connected to a gate terminal of the N-channel MOSFET. When the battery is properly physically connected to the drive circuitry, the charge pump is switched on and the N-channel MOSFET allows reverse current to flow from the motor drive to recharge the battery. When the battery is improperly physically connected to the drive circuitry, the charge pump is switched off and the N-channel MOSFET blocks current from flowing and damaging the battery.

Abstract: A system and method for identifying and responding to a condition in which an electric motor fails to start. A rotor core includes slots in which magnets are received to produce an electrical reluctance. A motor controller determines a position of the rotor, uses the determined position to convert a torque demand to a demanded D-axis current value, and compares the demanded value to a supplied D-axis current value. If the demanded value differs from the supplied value by at least a pre-established threshold amount, then the motor is restarted. Otherwise, the difference between the torque demand and an actual current is used to drive a voltage applied to the motor. The controller may also implement a sensorless technology, and may restart the motor if the demanded value differs from the supplied value by at least the threshold amount even if the sensorless technology determines that the motor started.

Abstract: A rotor assembly for an electric machine includes a rotor core that is fabricated from a plurality of laminations stacked along a rotational axis of the electric machine. The rotor core has a plurality of arcuately arranged, axially extending magnet-receiving slots. The rotor core includes a plurality of magnets received in respective ones of the magnet-receiving slots. Each of the laminations includes opposed deflectable magnet-retaining prongs that extend into a corresponding one of the magnet-receiving slots. The magnet-retaining prongs are deflected by and engage the magnets to exert a reactive force against the magnets and hold them in place. Each of the laminations also includes respective support posts axially adjacent the magnet-retaining prongs. The support posts extend alongside and thereby limit the deflection of the magnet-retaining prongs when engaged with the corresponding one of the magnets.

The electric motor is rotated using a servo driven functional tester and the BEMF waveform of the electric motor is measured. The sensor output signal waveform is measured, and the alignment plate is adjusted relative to the electric motor to align the sensor output signal waveform to the BEMF waveform. The alignment plate is secured to the electric motor in the adjusted orientation.
