The paper presents a new double layer three phase 3/6 pole-changing winding, with 72 slots and 6 terminals with “Y/YY with additional branches” ? “Y-Δ/YY” switching circuit. Using the discretely specified spatial function method, a two-speed asynchronous electric motor with a pole-switched winding was designed for self-propelled mine wagons, which were tested in static and dynamic modes of operation. The application areas of two-speed asynchronous motors with pole-switched windings are given. Currently, dynamic modes have not been investigated in the used two-speed engines. As the object of the study, a two-speed asynchronous motor of the AVTM - 6/12 brand of the self-propelled mine wagons drive was adopted in operating modes with no load on the shaft and when starting with a load of 500 Nm and switching to a second speed.
