In this paper investigated the without encoder drive for stepping motor using back electromotive force(B-EMF). In generally stepping motor should be rotary encoder to rotor position, the rotary encoder is adopted to detect the position. But in this way increase cost and volume. This paper propose B-EMF & closed-loop method was implemented using current detect circuit, AD-converter and MCU(micro controller unit). So that stepping motor environment is very simplify. The current of stepping motor was measured by using amplifier. The change of current was measured and analyzed, when the missing step occurred. Based on data from current feedback, position errors were compensated and it was confirmed by using AD-converter.
