Abstract :
This paper deals with the shape design for the reduction of stator core loss of the induction motor. The improved loss analysis is proposed which is based on core loss measurement under alternating flux with a certain harmonic component and elliptically rotating flux. The time step finite element analysis is used for the computation of state core loss of the induction motor
