Fengwu Zhu · Journal of Electron Devices · 2005
An effective approah improves the electromotor orientation accuracy for improving the position measure accuracy. The incremental magnetic rotary encoder, as a corner position sensor, can be improved its measure accuracy by the way of quadruplicated frequency circuit. The quadruplicated frequency IC was designed for the incremental magnetic rotary encoder. The work principle was analyzed. The structure of this logic circuit is strict proved by analyzing the logic expression. The accuracy and stability of the circuit was explained in principle. The emulation of timing cycle diagram and IC package diagram of its input and output pins are given.
