摘要： An apparatus includes an inner rotor motor and a stationary wiring conduit. The inner rotor motor includes a stator and a rotor spaced at least in part radially inside the stator. The rotor is rotatable relative to the stator about an axis. The rotor includes a rotatable shaft that presents a shaft bore extending axially therethrough. The stationary wiring conduit extends through the shaft bore and is fixed relative to the motor housing. The shaft bore rotatably receives the wiring conduit, such that the wiring conduit is permitted to remain stationary as the shaft rotates.

摘要： A stator of an electric motor includes a core and a covering overmolded on the core. The mold for overmolding the covering on the core includes first and second cavity-defining portions and pluralities of first and second pins extending at least generally toward opposite ones of the cavity-defining portions. The cavity is configured to receive the core therein. The first pins and the second pins are configured to extend into the cavity when the mold is in the closed position to cooperatively at least in part secure the core in the cavity.

摘要： An electric motor includes a stator, a rotor, and weights removably attached to the rotor shell for use in balancing the rotor. The removable weights may be integrally formed with a rotor shell such that the weights and the rotor shell form a unitary, one-piece construction. The removable weights may be substantially uniformly spaced apart around an entirety of the outer perimeter of the rotor shell. In a method of making an electric motor, the stator is coupled to the rotor such that the weights are accessible for selective removal during balancing of the rotor.

摘要： A method of assembling a motor for use in a machine is disclosed. The motor includes an axially extending rib protruding radially outwardly from the radially outer surface of the core. The motor further includes a groove-defining portion that defines an axially extending groove receding radially outwardly from the radially inner surface of the shell. The motor assembly method includes the steps of: (a) heating at least the groove-defining portion of the shell; (b) rotationally orienting the core and the shell so as to axially align the rib and the groove; (c) axially receiving the core within the shell such that the rib is received in the groove without interfering with the groove-defining portion; and (d) cooling at least the groove-defining portion so that the rib is fit within the groove via an interference fit.

摘要： An electric motor includes a stator, a rotor rotatable relative to the stator about a rotor axis, a motor case, and a motor controller. The motor case presents a motor chamber in which the stator is located. The motor controller is supported relative to the motor case and includes a heat-producing component external of the motor chamber. A heat sink is thermally coupled with the heat-producing component of the motor controller and is located within the motor chamber. A dripshield cooperates with the motor case to define a controller chamber in which the controller is at least substantially located. The dripshield and motor case present complementary pairs of latch components, with each pair of latch components including a dripshield latch component and a case latch component. Each pair of latch components is automatically interlocked to secure the dripshield on the motor case.
