摘要：
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.
