Increased efficiency of tests of electric machines of various types

Abstract

The paper describes the issues of operation of electric machines of various types. A wide adoption of asynchronous electric drives in various fields is noted. The relevance of the issue of embedding test complexes at companies conducting repairs, both asynchronous motors and direct current machines with different excitation types, is justified. The importance of the application modern power-saving technologies in the process of repair of electric machines is noted. One such technology is the method of mutual loading. Proposed scheme makes it possible to carry out tests by means of method of mutual loading such as induction motors, and direct-current machines with serial and independent (parallel) excitation. The effect is that the proposed scheme has a much lower cost compared to the total cost of schemes designed for testing of electric machines of the same types.
