Abstract :
A new time-stepping 3-D analysis method for analyzing induction motors is proposed. The method can analyze induction motor with faster computation time and less memory requirement than conventional numerical methods by using only scalar potential. The analysis model is divided into hexahedral elements and then an equivalent magnetic network is constructed by connecting the node of each element center. Also, the MMF by induced current combines passive source into the network. From comparisons between the results of analysis and experiments, it is verified that the proposed method can estimate the torque, harmonic field, etc. versus time with good accuracy
