Abstract

The article describes a method for sensorless determining of rotor angular position in a synchronous motor by means of superimposing a high frequency signal. The scheme of the laboratory bench for the experiment is described. A formula for rotor angular position calculation of a synchronous motor was developed. It was concluded that the developed method makes it possible to reduce the cost and the size of the system for determining the angular position and increase its reliability.

Keywords
