A Study on the One-chip Design of Low Cost for Micro-stepping Drive of 5-Phase Stepping Motor Having Pentagon Type Winding

5상 펜타곤 결선방식 스테핑 모더의 마이크로스텝 구동을 위한 저가형 전용 칩 설계에 관한 연구

In this paper, studied on the one-chip design of low cost for the micro-stepping drive having 5-phase Pentagon Type winding. Micro-stepping method in order to eliminate effectively the resonant phenomena and to Increase the positional resolution. This paper proposed trapezoidal current wave- form for current control and provided design- method by using only one-chip of low cost. Therefore the drive will be simple and small size. Also the drive will have a lot of advantage at commercial business. Finally the above study has been implemented on the VHDL. Simulation has been performed to verify the PWM for micro-stepping drive.
