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.

Using Analytical Approach with Finite Element Analysis for Coupling Magnetic and Thermal Analysis for Motors

Thermal analysis is a key factor when designing motors. We propose to link the studies of electromagnetic and thermal aspects in transient application with Finite Element Method (FEM) to represent the thermal state of motor with higher accuracy. As electromagnetic response time is different of thermal response time, an original method is used for extracting average values on one magnetic period of losses (Joule and iron losses), and to use them as input for the transient thermal analysis. So, the temperature in different parts of the motor is extracted, and brought back as input for the next electromagnetic computation.

Multiphysics - A New Generation of Simulation

The application of CAE early in a product’s design cycle can make an important difference in its cost and functionality.  However the level of fidelity of the design early in the cycle limits the application of many traditional CAE tools.   Fortunately this is where systems modeling can be applied due to the nature of utilizing a more abstract representation of the overall system and its components.
