| Abstract: | A mathematical model on steady states of a 3-phase tangential-field permanent-magnet(TFPM) synchronous motor of 18.5 kW and 6 poles is developed.The finite element equations under assumptions as well as the solving regions of the derived model are presented.Then the steady states electromagnetic field of line-start permanent-magnet synchronous motor is calculated by inner-outer double-convergence;and the loading torque and loading current can be calculated exactly.At the same time the effect of the variation of flux barrier of rare-eart size and the permanent magnet size on steady states performance of the motor is analyzed. |
