First Claim
1. A motor speed control system comprising:
- a motor having an output shaft;
a gear reduction assembly operably coupled to the output shaft;
a detectable element located in the gear reduction assembly; and
at least one sensor to sense the detectable element, the at least one sensor placed in the radial path of the detectable element, the at least one sensor in data communication with a controller configured to receive a signal from the at least one sensor and to control the speed of the output shaft.

Abstract
Motor speed control systems are disclosed that include a motor having an output shaft, a motor speed control system, a sensor to detect the speed of the motor, and a controller to receive a signal from the sensor and to control the speed of the output shaft. A gear reduction assembly is operably coupled to the output shaft and a detectable element located in the gear reduction assembly. The sensor senses the detectable element. The sensor is placed in the radial path of the detectable element. Another system includes a brushless motor having a housing and an output shaft, the brushless motor comprising electromagnetic field coils arrayed radially around a central magnetic shaft, a gear reduction assembly operably coupled to the output shaft, and a sensor placed in proximity to the brushless motor. The sensor communicates with a controller to control the speed of the output shaft.
