Changing the design of a synchronous motor after testing

Abstract

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.
