Abstract :
The described study involved interior permanent magnet (IPM) motors with distributed and concentrated (non-overlapping) stator windings. The machines were operated with sine-wave current-regulated power electronic drives. A coupled finite element model was used for the electromagnetic field and electric circuit analysis. Special instrumentation was employed for the measurement of 3D forces. It is shown that stator winding parallel paths can be very effective in reducing the effect of motor faults and asymmetries, such as rotor eccentricity.
