In the present study, a 5.5 kW, 22 pole direct drive surface mounted PM synchronous motor (PMSM) has
been designed, analyzed and optimized. After an initial design stage, a 3D model of the generator has been created for
the finite element analysis. Cogging torque, output power, efficiency and maximum output power parameters have been
analyzed for various material of PM magnets (Alnico, Ceramic, SmCo, NdFeB), which can be produced easily by rareearth
elements. In the performed analyzes, the best efficiency and the maximum output power value has been obtained
on the N50m type magnet material. Furthermore, the lowest cogging torque has been obtained with an Alnico5 type
magnet material.

In recent years, due to their superior features, interior permanent magnet (IPM) motors are often preferred in
traction applications such as electric vehicles. The rotor geometry of an IPM motor significantly affects motor
performance. To improve the electromagnetic performance of the IPM motor such as maximum torque per ampere
(MTPA), efficiency, and the torque pulsations, rotor and its flux barriers geometry have to be optimized due to the
difficult modeling dominated by magnetic saturation. Thus, this study is focused on the optimization of flux barriers by
varying the rotor geometric parameters which have significant influences. Performance and the electromagnetic
parameters of the motor are verified by using 3D-Finite Element Method. The proposed motor has the following
parameters; 4-pole, 48V, 500W and 3000rpm.
