Abstract

PURPOSE:To eliminate a position detecting encoder and to enhance the responding speed of a stepping motor by winding a generating coil superposed on a stator coil, interposing a transformer between the coils to erase an induced voltage due to the stator coil, thereby producing a position detection signal. CONSTITUTION:In a permanent magnet type stepping motor having two sets of stator coils L1, L2 in which currents I1, I2 of different phases of 90 deg. from each other are flowed, generating coils G1, G2 for generating currents of 2 phases at 90 deg. from each other are repsectively wound and superposed on stator coils L1, L2. Transformers T1, T2 respectively having electric constants equal to mutual electric constants of the L1, G1 and L2, G2 are provided externally at the motor. The stator coils L are respectively connected in series with the primary coil of respective transformers T, the generating coils g are connected in seres in opposite polarity to the secondary coils, AC outputs from terminals D1, D2 are converted via zero-cross detectors into 2-phase pulse signals, thereby obtaining a position detection signal.
