  • Publication number: 20240075797
    Abstract: An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a second electric motor that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a clutch. The electric powertrain further includes a first gear train in the form of a first planetary gear and a second gear train in the form of a second planetary gear. In one form, the first electric motor and second electric motor are the same type of electric motor, and in another form, the first electric motor and second electric motor are different types of electric motors.

  • Patent number: 10707718
    Abstract: An electric motor includes a stator assembly and a rotor configured to rotate within the stator assembly about an axis. The stator assembly includes a stator case having a channel and a laminate steel core having a retention feature aligned with the channel of the stator case. The stator case is fixed to the laminate steel core via displacement of material of the stator case at the channel toward the laminate steel core to capture the retention feature. An electro-mechanical drive-unit employing the above-described electric motor and a method of generating a stator assembly for such an electric motor are also contemplated.
