  • 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.

  • Lightweight rotor endplate for electric machine
    Patent number: 10199906
    Abstract: An electric machine is disclosed. The electric machine may include a rotor and an endplate. The endplate may define an aperture, an inner locknut surface and a balance-ring surface. The locknut surface may extend from a periphery of the aperture to a first diameter. The balance-ring surface may extend from a second diameter that is greater than the first diameter to an outer periphery of the endplate. Before assembly, the balance-ring surface may be adjacent to the rotor and the locknut surface may be spaced apart from the rotor.

  • ROTOR ENDPLATE FOR ELECTRIC MACHINE
    Publication number: 20180278126
    Abstract: An electric machine is provided. The electric machine may include a rotor disposed on a shaft and an endplate. The endplate may define a coolant capture ring. The coolant capture ring may have tapered side walls that extend from an outer portion of the endplate toward the shaft at a periphery thereof. The coolant capture ring may be configured to deflect coolant captured by the coolant capture ring and expelled by the shaft due to centrifugal forces associated with the rotation of the shaft.
