Abstract: A permanent magnet electric machine includes a rotor configured to rotate about an axis. The rotor is comprised of axially stacked sections. Each section is comprised of axially stacked laminations that define a pattern of axial grooves on an outer surface of the rotor to reduce torque ripple. The pattern is different for at least two of the sections. The pattern for each section may alternate with respect to poles of the rotor.

Abstract: A discontinuous pulse width modulation technique is used in a controller to control an inverter that converts DC battery power to AC power to operate an electric motor, e.g., in a hybrid electric vehicle. The discontinuous pulse width modulation technique uses only one of the two zero state voltage vectors in its calculations whereas traditional pulse width modulation uses both zero state voltage vectors. The use of a single zero state voltage vector can result in one of a group of switches in the inverter remaining in a constant state during a complete duty cycle while still providing the commanded voltage vector to the electrical motor. As a result losses due to switching can be reduced.

Abstract: A battery electrical vehicle or plug-in hybrid electric vehicle includes a battery which may be charged by an electrical charging station coupled to the electric power grid. To maximize the charging efficiency thus decreasing charge time, the voltage and current drawn from the power grid may be closely monitored. Based on the monitoring of the voltage and current of an electrical circuit powering a battery charger, a notification of changing conditions to charging characteristics including electric circuit wiring resistance, power loss or wiring efficiency may be generated.

Abstract: An embedded controller in a vehicle electronics subsystem includes a signal processing circuit used to communicate with an electric machine. The signal processing circuit may be configured to receive an input signal from the electric machine and provide digital output signals to the embedded controller. The digital output signals may include Hall position and rotor position signals. Once the digital output signals are processed by a processor embedded within the controller, the processor may issue a control command to the electric machine. The processor may have memory containing software to make the processor execute the computation of the control command of the electric machine in accordance with a torque command.

Abstract: A hybrid-electric vehicle and method of controlling a hybrid-vehicle is provided. The vehicle includes a traction battery, at least one electric-machine, and a controller. The controller is configured to alter a voltage between the battery and the electric-machine based on a measured voltage of the battery or the high voltage bus. In response to an indication that the measured voltage is faulty during a drive cycle, the controller instead alters the voltage between the battery and the electric machine based on a substituted battery voltage signal such that the electric-machine remains operable for the drive cycle.
