Winding reconstruction based on magnetic flux density in air-gap of IM

This paper deals with a reconstruction of a three-phase winding based on the knowledge of a course of magnetic flux density in the air-gap of an induction motor. The paper is divided in two main parts. The first part deals with introduction of measured motor and comparison of measured courses of speed and stator currents with simulated results. The second part deals with analysis of magnetic flux in the air-gap and reconstruction of the winding. There is derived an equation for calculation of a total number of winding conductors based on the magnetic flux density in the air-gap.
