VECTOR CONTROL OF HYBRID STEPPER MOTOR

Peter Šuda - Milan Zalman

   In the area of vector control of stepper motors, voltage inverters either with or without current regulation are common. There are two extremes. Very low speed operation asks for sufficiently reasonable velocity feedback. On the other hand, extended speed area needs optimal field weaking. In both cases fast response to a load distortion is required. The goal of this paper is to introduce a servosystem which complies with the most severe claims for servosystems.
