Open-loop control of hybrid stepper motor with two phases using voltage to frequency converter

Positioning systems are powered by different types of electric motors. A special category of electric motors, which are increasingly used in systems, are hybrid stepper motors (the most common example are with two phases). Due the simplicity of construction, command and control, they are used even in other electric drive systems. This paper presents a new method of Matlab simulation of a controller driver for a hybrid stepper motor with full step sequence, using a voltage to frequency converter. The results of the simulation of the proposed control scheme are quite satisfactory.
