A Study on The Rotor Position Detection of Bifilar-Wound Hybrid Stepping Motors
초록
In this paper, we show that the rotor position of the bifilar-wound hybrid stepping motors for the closed-loop drives is detected by the phase current measurement. We propose an instantaneous phase current equation, which is the function of electrical angle, by the modeling of the stepping motor including motor driving circuits. We also analyze the relationship between phase current and rotor position from the computer simulation results. It is shown that the information about the rotor position is obtained from the phase current amplitude and its derivatives at the instance of
