ABSTRACT:
The present invention provides an internal braking system for use with electric motors, particularly electric motors used with rotary actuators. The braking system includes a brake which has a spindle disposed at least partially between the rotor and a shaft. An annular engagement portion of the brake is integrally connected to the spindle through a conical portion. The brake is forced against a stationary friction member when the motor is de-energized. The brake is preferably made from a polymeric alloy having self-lubrication properties.
