ABSTRACT:
A motor assembly (10) includes a permanent magnet DC motor (16) having a shaft (24) mounted for rotation with a face gear pinion (26) associated with the shaft. A jack shaft and clutch assembly (18) is associated with the face gear pinion and is constructed and arranged to prevent back drive of the motor under certain operating conditions. A spur or helical pinion (40) is operatively associated with the jack shaft and clutch assembly. A drive member (56) is operatively associated with the spur or helical pinion such that movement of the shaft and face gear pinion moves the spur or helical pinion to drive the drive member. A housing structure is defined by an upper housing (14) joined with a lower housing (12). The motor, the face gear pinion, the jack shaft and clutch assembly, the spur or helical pinion and the drive member are housed within the housing structure. Only one of the upper or lower housings includes mounting structure (25) constructed and arranged to mount the motor assembly to another object.
