Abstract This paper presents an accurate calculation method to extract parameters of canned solid-rotor induction motor from finite element analysis of electromagnetic field. The 2-D time-harmonic application is used in the accurate simulation. The Fourier analysis method is applied to obtain the basic wave of air-gap flux density, and the then electromotive force is further calculate. The frozen permeability method is also used to take the iron saturation into consideration in whole operating range. The Poynting-vector in the edge of rotor region is derived to get the value of complex power flowing into the rotor side, and the equivalent parameters of rotor can be further determined. Finally, the proposed approach is verified by both numerical and experimental solutions.

Key words： Canned solid-rotor induction motor time-harmonic field equivalent circuit Poynting- vector
