ABSTRACT:
In the course of regulating an electronically commutated d.c. motor as the drive motor of a winding device of a textile machine, the resolution of known angular rotation sensing systems is insufficient to assure a jerk-free drive of the drum at low rpm. It is therefore proposed by the invention to introduce a so-called Luenberger observer into the regulating circuit for regulating the motor rpm in which the signals of the angular rotation sensing system for the commutation of the motor are generated.
