... diagram of a DC motor control system toshow the sensor feedback provided for a typical motor control. A list of the sensors that can be used to feedback information to a microcontroller are listed ... reliability ofthe motor by detecting fault conditions that maydamage the motor. The four major feedback sensors discussed in thisdocument are: current sensors, back EMF orsensorless control, quadrature ... Inc.CONCLUSION Feedback sensors serve a critical role in a motor control system. These sensors provide information onthe current, position, speed and direction of a rotating motor. In addition, the sensors...
