摘要: An electric motor is disclosed and which includes a braking element which is biasingly urged into a braking relationship relative to the electric motor, when the electric motor is deenergized, but which is further moved out of braking engagement when the electric motor is energized. The invention finds particular usefulness when used on hand tools, such as angle grinders.

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.

摘要: A drive motor includes a stator and a motor rotor. The motor rotor is mounted for rotation relative to the stator. The stator includes a first plurality of poles with each pole being surrounded by a coil. The motor rotor includes a second plurality of poles. Current is switched between the coils to bring poles from the second plurality of poles into alignment with corresponding poles from the first plurality of poles to rotate the motor rotor and generate an output torque to drive a vehicle component. A brake rotor is formed on an end face of the motor rotor. Brake pads are selectively brought into frictional contact with the brake rotor to generate a braking force for the vehicle component.
