Numerical Modeling and Experimental Analysis of the Magnetic Noise of the Single-Phase Inverter-Fed Permanent Split-Capacitor Motor_Andrei NEGOITA_OPTIM

Abstract- The paper presents a FEM approach for studying the influence of the capacitor value on the magnetic noise of a network and inverter-fed permanent split-capacitor induction motor. A 4 pole, 24 stator slots and 30 rotor slots, induction motor is modeled under Flux2D Finite Element software in order to determine the amplitude and frequency spectrum of the magnetic forces acting on the stator. The effects of the inverter supply are taken into account by coupling Flux2D with Matlab/Simulink. The results are compared with those obtained from noise measurements performed on the studied motor.
