<p>A motor includes a stator, a rotor supported by a rotor hub for rotation relative to the stator, and a housing fixedly supporting the stator. The housing rotatably supports the rotor and includes a first end enclosing the stator, the rotor, and the rotor hub and a second end exposing the stator, the rotor, and the rotor hub to define an opening between the rotor and within the rotor hub.</p> |
