“…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 problem of creating pole-changing windings (PCW) for multi-speed electric motors was dealt with by many scientists from around the world [4,5]. Series twospeed motors with a pole pair ratio of 1/2 have a polechanging Dahlander winding in the stator [6,7]. Pole changing method is one of the main methods of the speed control of an induction motor.…”

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.

“…Porém, os motores Dahlander também podem operar em mais do que duas velocidades. Existem estudos onde a alimentaçãoé feita com frequência variável, de modo a se obter uma larga faixa de controle de velocidade em veículos elétricos (Rohit et al, 2018;Van der Giet et al, 2007).…”

Este trabalho apresenta a transformação de um motor de indução trifásico convencional em um motor do tipo Dahlander. O enrolamento e desenvolvido para que cada fase tenha quatro terminais acessíveis, de modo que seja possível ao usuário realizar ligações que permitam o motor funcionar em três modos de operação: conjugado constante, conjugado variavel e potência constante. São realizados testes de corrente contnua, a vazio e de rotor bloqueado para a determinação dos parâmetros do motor em cada uma das ligações. Com base nos parâmetros obtidos são traçadas as curvas de conjugado e densidade de corrente versus velocidade, e essas são comparadas com os resultados encontrados na bibliografia existente.
