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.
