“…This process is based on the principle of approximation of the current distribution to the picture of the MMF of the PCHW from the pole side 2p1 to the current distribution and the picture of the MMF of a typical winding. The meaning of the "approximation" is to determine in each groove the sign of the state of the DSSF conductor of the synthesized winding, depending on the state of the DSSF conductor of a typical winding in this groove and based on the relative position of the phase current vectors in a three-phase system [7,8].…”

In the world, many enterprises in the mining, metallurgical, paint and varnish, chemical industries, as well as in the production of building materials, pay special attention to the problems of starting and accurately stopping ball mills.This article substantiates the expediency of using an adjustable electric motor in grinding mechanisms in electric drives instead of an unregulated asynchronous motor.The problem of facilitating the start-up of ball mills and ensuring accurate stop of the neck of ball mills using the lowest speed is considered. As the review of the literature showed, speed control in electric drives using two-speed motors is a simple, cheap and reliable option.

“…Undoubtedly, the second kind of construction has a lot of advantages due to a smaller slot area occupied by one winding. This allows one to use the active part of the electric machine more efficiently, increase energy parameters, simplify manufacturing and repair technologies [1][2][3][4][5]10].…”

This paper investigates the possibilities for developing a pole-changing winding with a pole ratio of 3:4 with improved electromagnetic properties. Such a winding can be used in two-speed induction motors for turbo mechanisms. The scheme of the new winding was obtained by using a discretely-specified spatial function method developed at the Tashkent State Technical University. A comparison of the parameters obtained for a similar winding received by the pole amplitude modulation method has been presented. Design of a new motor with a new winding is developed based on the standard induction motor. The paper presents results of laboratory tests, too.

“…The number of stator poles can be changed by pole amplitude modulation (PAM) method [8,9] The method is used both for close ratio as well as for wide ratio [10]. Twospeed motors with pole ratio 2/3 and 3/4 are made with pole-changing windings obtained by the phase modulation method [11,12].…”

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.
