Integrated Position Sensor for Hybrid Stepping Motor Servo System Based on DSP

摘要

Rotor position detection is important for servo system design. A new integrated position sensor is described in this paper. The sensor is easy to manufacture and has better precision with easier signal processing circuit and software based on DSP. The sensor is used in a 2-phase hybrid stepping motor position servo system. The integrated sensor and the proper control strategy make the system become a low-cost high-performance position servo system.
