ABSTRACT:
An electric motor assembly has an inner-rotor configuration including a hollow space within the rotor hub. The hollow space houses at least part of a brake for providing a braking force between a rotor and a stator of the electric motor. The brake can be configured to provide a braking force when no power is flowing to the electric motor, and can have an outer diameter less than an inner diameter of the rotor.
