Optimization of a single-phase capacitor induction motor by applying a field-circuit model

Abstract

The paper presents optimization of the singlephase capacitor induction motor by 2D field-circuit model combined with response surface methodology. Developed fieldcircuit model was implemented for simulation using Flux2D software package. The dimensions of rotor slot and capacitor capacitance are treated as input variables whereas functions describing motor performance are outputs (objective and constraints). The optimization goal is to find a motor configuration with maximal efficiency and starting torque. The model is suitable for study the effect of parameters of the motor on starting and running performance under desired load. For this purpose, the sensitivity analysis of chosen parameters had been performed before the optimization problem was formulated. Some results of motor efficiency optimization are presented in the paper.
