  • System and method for in-vehicle resolver alignment
    Patent number: 11081948
    Abstract: An electric drive system for a vehicle includes a speed/position feedback device coupled to an electric machine and configured to provide an index pulse. The system further includes an inverter having a line voltage sensor. The system includes a controller programmed to, responsive to the electric machine rotating at a generally constant speed without commanding the inverter, generate a resolver offset from a time difference between a zero crossing of a line voltage and the index pulse and operate the inverter according to the resolver offset.
    Type: Grant

  • Shaft assembly for an electrified vehicle and shaft providing method
    Patent number: 11028873
    Abstract: An electrified vehicle assembly includes, among other things, an outer shaft that is rotatable about an axis. The outer shaft rotatably couples a motor of an electrified vehicle to a transmission component of the electrified vehicle. A shaft insert provides a conduit for a fluid and that blocks the fluid from flowing radially between the shaft insert and the outer shaft relative to the axis. The shaft insert includes a polymer-based material, a composite material, or both.

  • Motor shaft assembly and assembling method with an insert that provides a fluid conduit
    Patent number: 10352351
    Abstract: An exemplary shaft assembly includes an outer shaft rotatable about an axis, and a shaft insert that provides a conduit for a fluid and blocks the fluid from flowing radially between the shaft insert and the outer shaft relative to the axis. An exemplary shaft assembling method includes positioning a shaft insert within an outer shaft. The shaft insert has a fluid conduit and is configured to block fluid from communicating radially between the shaft insert and the outer shaft.
