The development and analysis of a new pole-changing winding with pole ratio 2p1/2p2=4/6, as well as the experimental research of a two-speed induction motor with this winding, involved the use of modernized methods such as Discretely Specified Spatial Function (DSSF). These methods have been used to develop pole-changing winding designs for two-speed induction motors with improved electromagnetic properties, closely resembling conventional windings. The new pole-changing winding could be aviable alternative to conventional two-layer windings, as it offers similar electromagnetic properties. Furthermore, the new pole-changing winding was analyzed using ANSYS/Maxwell and tested on an induction motor built on the base of a 1,5 kW/1500 rpm induction motor in frame 4A80U3, developing 1,1 kW/0,7 kW rated power for 2p1/2p2=4/6 poles, respectively. Overall, this research demonstrates the potential for developing advanced pole-changing windings with improved electromagnetic properties and their application in practical induction motors.
