Abstract: In at least one embodiment, a single sintered magnet is provided having a concentration profile of heavy rare-earth (HRE) elements within a continuously sintered rare-earth (RE) magnet bulk. The concentration profile may include at least one local maximum of HRE element concentration within the bulk such that a coercivity profile of the magnet has at least one local maximum within the bulk. The magnet may be formed by introducing alternating layers of an HRE containing material and a magnetic powder into a mold, pressing the layers into a green compact, and sintering the green compact to form a single, unitary magnet.

Abstract: An internal permanent magnet machine has multiple rotor sections, each section having multiple rotor laminations. Permanent magnets are placed asymmetrically in lamination openings to attenuate oscillations in torque caused by harmonic components of magnetic flux. Asymmetry is achieved by placing adjacent permanent magnets or magnet sets on the rotor periphery with different rotor magnetic pole arc angles.

Abstract: An electric drive system is actively controlled while an electrified vehicle is being towed. The inverter switches are manipulated to preclude exceeding a maximum voltage of a DC bus and also to preclude exceeding a maximum phase current magnitude. During a transition from an inverter off state to a short-circuit state, field-oriented control is utilized.

Abstract: Systems and methods for commanding an electric drive system for an electric or hybrid vehicle are described. In one example, the drive system is commanded by a controller that supplies a pulsed torque command that varies in magnitude as a function of time when a driver of a vehicle requests a constant driver demand torque.

Abstract: An automotive power system includes a traction battery, an electric machine, and one or more power cards each containing at least one power semiconductor switch and at least one Y-snubber that includes a series connected capacitor and resistor. The power semiconductor switches are arranged to form an inverter electrically connected between the traction battery and electric machine. The resistors are tuned to dissipate common mode noise associated with operation of the power semiconductor switches.
