Patent attributes
An electric brake assembly for a planetary reduction drive includes a first housing defining a brake housing compartment, first and second stators disposed within the brake housing compartment, and a rotor disposed within the brake housing compartment between the first and second stators. The rotor has a spline engaging an output shaft of a motor. The electric brake assembly also includes a brake end cap coupled to the first housing and defining a cylindrical volume, a plug movably disposed in the cylindrical volume of the brake end cap, a spring disposed within the cylindrical volume of the brake end cap and compressed by the plug to apply a spring biasing force for pressing the second stator against the rotor, and an electric brake coil positioned adjacent to the second stator to electromagnetically pull the second stator away from the rotor when energized.
