Hall Effect Based Tracking Position Sensor

Abstract

The photoelectric encoder can not be applied to the harsh environments with intensive vibration, moisture, oil and dust, and has the disadvantages of complex manufacturing crafts and high cost. To solve the problems above, a hall effect based tracking position sensor is proposed. Firstly, the magnetic signal reflecting the shaft velocity and position is converted into an electrical signal with the hall component. Then, the resolver-to-digital conversion is carried out by arctangent. And finally, the signals of shaft position and velocity are obtained.
