Abstract
Reducing electrical losses and increasing energy performance are priorities when designing electrical machines. In addition, increasing initial costs related to electric machine manufacturing owing to an increase in the consumption of active materials are relatively quickly compensated by decreasing operating costs. For single-phase motors, in particular, the capacitor induction motors with electric and magnetic asymmetry, improving ways of reduce electric losses is a very important problem, to solve which it is necessary to study processes of their symmetrization. The design procedure of working and energy characteristics of induction capacitor motors based on the results of solution of electromagnetic equations is proposed. The parameters of phase-shifting capacitor and the motor transformation ratio are determined at which there is a circular magnetic field within the air gap. It is shown that the calculation results can be used for building the graph dependences of transformation coefficient, capacitor capacitance, and capacitor voltage on slip and subsequent analysis of these curves to obtain the most appropriate solutions.
