This paper presents a method to analyze magnetic field with accuracy by 2DFEM in shaded-pole type induction motor. That is to say, the equations of electric circuits which consist of the rotor bars are coupled with Maxwell's field equations directly to solve the currents in the rotor bars regardless of ‘grad φ’. And in the same way, all other secondary currents are solved with accuracy. Then the motor torque can be calculated by using the currents and the variations of the interlinkaged flux in the rotor bars.
When the calculated results by this method are compared with the measured results, the good agreement is obtained.
