Optimalizace aktivních částí asynchronního motoru 4p 200kW

Abstract

The aim of this diploma thesis is to provide the basis for the design department of the electric motor manufacturer for the design of a new asynchronous motor 4p 200kW which will meet the performance criteria for class IE4 according to IEC 60034-30 with the minimal material and production costs. The introduction mentions the tendency of continuous efficiency requirements increase in electrical equipment. The second chapter describes the basic design of the asynchronous motor and the principle of function. The third chapter focuses on the theory of loss emergence in the motor. The fourth chapter is devoted to the requirements on the effectiveness of electric motors from the point of view of the legislation. The fifth chapter is devoted to the basic description of the finite element method and describes ANSYS Maxwell software. In the sixth chapter, the basic description of an optimized engine can be found. The seventh chapter deals with the creation of the basic numerical model and its tuning. Then basic electromagnetic simulations are carried out using the finite element method. Eighth chapter deals with the optimization of asynchronous motor 4p 200 kW to meet the performance criteria for class IE4. In the conclusion, the final models that meet the performance criteria for class IE4 are presented.
