Abstract :
This paper presents a study of buried (i.e., interior) permanent-magnet (PM) synchronous machines (IPMSM) performances. Three IPMSM with distributed windings are designed and compared. They have identical: output power, stator and rotor outer diameter, air-gap, axial length, PMs volume.... Comparison of the back electromotive force (EMF), the short circuit current, the electromagnetic torque (average, cogging and ripple) and the 2-D PM eddy-current at no-load losses are given. The performances comparison of the for three machines (i.e., IPM I, IPM V and IPM U) is achieved using two-dimensional (2-D) finite-element method (FEM).
