This invention relates to a permanent magnetic stepping motor. Its object is to provide a permanent magnetic stepping motor which is simple structure, easily minitype, and can feel its work state by itself. The summary of this invention if that there is a permanent magnetic stepping motor, which includes a stator and mover, and the stator is formed to a coil-pipe having multiple taps by winding a single coil, and the mover is a permanent magnet which arranged NS pole on the opposite ends and provided within the coil-pipe along the direction of paralleling to the coil-pipe, and there are feedback coil adding on two ends of the permanent magnet. The advantage of the motor according this invention is simple structure, working with high speed, adding the function of autocontroling, and it also can realize the intelligentize of the feedback coils and making the computer communicate with environment through the stepping motor.
