Integrated Position Sensor for Stepping Motor Servo System Based on Inductance Detection and DSP
Rotor position detection is important for phase communication in stepping motor drives, while it is operating as a closed-loop servomotor. This paper describes a new integrated position sensor for a hybrid stepping motor. The sensor has no electronic connection and has little magnetic connection with the motor. The sensor is easy to manufacture and has better precision with easier signal processing circuitry.
