The essential advantage of the conventional stepping motor drive technique bases on step command pulses is the ability of open-loop positioning. By ruling out the cost of a position sensor, stepping motors are preferred in low power positioning applications. However, machine developers also want to obtain high dynamics with these small and cheap stepping motors. For that reason, stepping motors are used at its limits as much as possible. A drawback of the open-loop control is the continuous risk of missing a step due to overload. Due to this uncertainty, robustness is a major issue in stepping motor applications. Until today, to reduce the possibility of step loss, the motor is typically driven at maximum current level or is over-dimensioned with results in low-efficiency. Therefore in this paper, a self-learning [Formula: see text]-controller optimizing the current is presented. Moreover, to allow broad industrial applicability, this technique is computationally simple, needs no mechanical or electrical parameter knowledge and take into account the unique character of stepping motors and their conventional drive technique based on step command pulses. The proposed algorithm is validated through measurements on a hybrid stepping motor.

In this paper, the mechanical structure of a novel two-phase hybrid stepping motor, which offers big transmission ratio and fast response characteristics, is proposed. Comparing with typical two-phase hybrid stepping motor, permanent magnet of the new model is placed on the stator, thus it has better utilization of space than conventional two-phase hybrid stepping motor. Furthermore, new two-phase hybrid stepping motor torque mathematical model is established. And the two-phase hybrid stepping motor torque vector analysis method we provide here provide you with an intuitive way of research on the new type two-phase hybrid stepping motor operation principle and control mode.
