Abstract
There is disclosed a low power motor and brake assembly for a magnetic tape reel of a magnetic tape recorder/player. The magnetic tape reel is driven by a motor having a rotor fixed to the reel shaft and a stator which is rotatably mounted. A brake assembly includes a brake drum mounted on the reel shaft and a spring loaded brake band engaging the brake drum. One end of the brake band is attached to the stator by a linkage. When the motor is energized, the stator rotates and releases the brake band from the drum by means of rotation of the linkage.
