“…Feature-wise, linear switched reluctance machines (LSRMs) are very similar to LIMs. Their main advantages are their low material and manufacturing cost [53]- [55], simple structure [57], [64], [66], and their inherent ruggedness [61], [64]- [66].…”

This document reviews the current state of the art in the linear machine technology. First, the recent advancements in linear induction, switched reluctance and permanent magnet machines are presented. The ladder slit secondary configuration is identified as an interesting configuration for linear induction machines. In the case of switched reluctance machines, the mutually-coupled configuration has been found to equate the thrust capability of conventional permanent magnet machines. The capabilities of the so called linear primary permanent magnet, viz. switched-flux, flux-reversal, doubly-salient and vernier machines are presented afterwards. A guide of different options to enhance several characteristics of linear machines is also listed. A qualitative comparison of the capabilities of linear primary permanent magnet machines is given later, where linear vernier and switched-flux machines are identified as the most interesting configurations for long stroke applications. In order to demonstrate the validity of the presented comparison, three machines are selected from the literature, and their capabilities are compared under the same conditions to a conventional linear permanent magnet machine. It is found that the flux-reversal machines suffer from a very poor power factor, whereas the thrust capability of both vernier and switched-flux machines is confirmed. However, the overload capability of these machines is found to be substantially lower than the one from the conventional machine. Finally, some different research topics are identified and suggested for each type of machine.

In the course of work on the project, we have created a permanent magnet synchronous motor, which will be effectively used in the oil industry, or rather 2 models: 15and 55-kW motors. After the tests carried out, the problem with the achievement of the specified value of the efficiency of the engines was clarified, and it was necessary to solve this problem without significantly changing the design. One of the solutions is presented in the article.

The use of a digital controller in the loading system of the test bench to improve the accuracy of simulating the modes of oil pumping units

Modern trends in the development of technologies are based on the need to conduct experimental studies of the developed equipment in laboratory conditions with the maximum approximation of operating modes to real ones. Such studies are impossible without the development of specialized stands with test automation systems. In modern test equipment systems, devices are often used to create a mechanical load on the shaft of the electric motor under study. As such a device, a system of frequency converter load asynchronous electric motor has been proposed and implemented, which has been tested at the test bench and has proven itself from the best side in comparison with traditional circuits using DC motors.
