Paper investigates permanently split capacitor motor of type FMR-35/6, with respect to torque optimization. For this purpose, mathematical model of the motor is derived withudthe output torque as an objective function for optimization.udMotor mathematical model is applied in program developed inudthe C++ language, which performs the optimization usingudGenetic Algorithm (GA). Several input design parameters of the motor are varied simultaneously in the GA program. Theudprogram gives the best set of varied parameters for which the torque is increased, and consequently a new optimized model of the motor is obtained. Output torque of the optimized motor is increased at rated operating point as well as during motor start.Matlab/Simulink models are designed for obtaining the transient characteristics of the currents, speed and torque. The results from the Simulink models are compared with the results from theudmathematical models of the motor-basic and optimized, in order accuracy of the both mathematical models to be verified. Finally,magnetic flux density and its distribution in the cross-section of the motor models are determined for different operating regimes by using Finite Element Method (FEM).
