2003 Microchip Technology 1MAN894INTRODUCTIONSensors are a critical component in a Motor controlsystem. They are used to sense the current, position,speed and direction of the rotating Motor . Recentadvancements in Sensor technology have improvedthe accuracy and reliability of sensors, while reducingthe cost. Many sensors are now available that integratethe Sensor and signal-conditioning circuitry into a most Motor Control systems, several sensors areused to provide Feedback information on the sensors are used in the Control loop and toimprove the reliability by detecting fault conditions thatmay damage the Motor .
