Characteristic Improvement by using micro-step driver of 5 Phase step motor in soldering machine

5상 스텝모터의 미세스텝 구동방식에 의한 솔더링 머신의 성능향상

This paper is about improving characteristic of plant by using micro-step driver method in 5 phase step motor for satisfying the condition of low oscillation and high accuracy in soldering machine. We choose open loop control method for minimizing hardware system and use one chip microprocessor, power MOSFET nd some device to realize accurate micro-step driver system.
