Electric motor with passive integral brake

摘要

An electric motor (102) with passive integral brake (104) includes a stator (204) with one or more magnetic field controllable coils (206) and a rotor (208) with a rotor shaft (210) positioned within an inner diameter (212) of the stator (204). The rotor (208) is operable to rotate about a longitudinal axis (214) of the rotor shaft (210). The electric motor (102) with passive integral brake (104) also includes a brake shoe (302) positioned within the inner diameter (212) of the stator (204) along the longitudinal axis (214) of the rotor shaft (210). The brake shoe (302) is operable to apply a braking force to the rotor shaft (210) and remove the braking force from the rotor shaft (210) responsive to a magnetic field strength produced by the one or more magnetic field controllable coils (206). One or more springs (220) passively apply the braking force.
