  • Electrical machine
    Patent number: 10476322
    Abstract: An electrical machine has a nonmetallic housing having a stator band and an endplate, wherein the laminated stator core is in self-locked engagement with the housing. Another electrical machine has a unitary nonmetallic housing with an integral stator band and an integral endplate, wherein the laminated stator core is over-molded with the housing. Yet another electrical machine has a unitary nonmetallic housing with an integral stator band and an integral endplate, wherein the laminated stator core is in engagement with the stator band with an interference fit.

  • Motor with integrated drive unit and shared cooling fan
    Publication number: 20060284498
    Abstract: An integrated motor and drive assembly includes a motor, a fan, and a drive unit. The motor is responsive to at least one drive signal. The fan is axially aligned with the motor and operable to generate a cooling flow. The drive unit is axially aligned with the fan and operable to generate the drive signal. The cooling flow traverses the motor and the drive unit.
