Research of possibilities of characteristics and parameters increase of asynchronous machines

Abstract

Improving the efficiency and reliability of ship electric power systems is a priority task for modern shipbuilding. One of the ways to solve this problem is to use the power of the main power plant for the production of electricity. In this case, it is advisable to give preference to asynchronous machines as the simplest in production and reliable in operation. It should also be noted that the asynchronous machine can be made with a massive ferromagnetic rotor or a sleeve with the use of nanotechnology, which will improve the energy parameters and performance of the electrical machine and the system as a whole. The article analyzes the characteristics of the device and the operation of an asynchronous machine (AM) with a short-circuited rotor with a ferromagnetic sleeve. Dependence of AM parameters and characteristics on the geometric dimensions of the sleeve is shown, and a technique for their determination using the system of Maxwell differential equations is proposed. An algorithm for calculating the characteristics of an AM machine and the equivalent parameters of a ferromagnetic sleeve is developed.
