Abstract
The article considers the issues of increasing energy efficiency by using multi-speed motors, and also considers the problems of creating pole-changing windings. The procedure for constructing a new two-layer three-phase pole-changing winding with a pole ratio of 4/6, made in 36 stator slots on the basis of the basic switching scheme YYY/YYY, is presented. Based on the results of the analysis of the electromagnetic properties, the optimal winding pitch was selected. An experimental motor with a new pole-changing winding was created on the basis of a magnetic circuit of a serial asynchronous machine of the 4?132?4 type. The analysis of the properties of the electric motor was carried out using the ANSYS/Maxwell program. The results of experimental tests of a new two-speed motor in static and dynamic modes are also presented.
