Abstract
Disclosed are systems and rotor/stator assemblies with improved electrical isolation. An example rotor/stator assembly may include a rotor, a rotor housing, a rotor insulator, a stator, a stator plate, and a stator insulator. The rotor may be electrically isolated from the rotor housing by the rotor insulator, and the stator may be electrically isolated from the stator plate by the stator insulator. The stator may be disposed coaxial to the rotor. The rotor/stator assembly may function as a motor, and the stator may be configured to cause the rotor to rotate about the stator in response to an input of electrical energy to the stator. Alternatively or additionally, the rotor/stator may function as an electrical generator. The rotor may be configured to rotate about the stator, and the stator may be configured to produce electrical energy in response to rotation of the rotor relative to the stator.
