In this study, it was aimed to carry out the design, electromagnetic analysis and noise-vibration analysis of a 3 phase, high efficient surface-mounted permanent magnet motor with a power level of 7.5kW and 1500rpm speed. Using basic analytical formulas initial design geometry of motor was obtained. This first design geometry was investigated in detail by electromagnetic analyzes. In these electromagnetic analyzes, cogging torque, torque ripple, losses and efficiency parameters have been investigated. Then, modal and harmonic analyzes were carried out in order to interpret the effect of radial harmonic forces, obtained from electromagnetic analyzes, on the stator teeth on the noise and vibration parameters of the motor. According to analysis result of initial designed motor, it was aimed to reduce cogging torque, torque ripple, efficiency, noise and vibration parameters. It is thought that the improvement studies to be perform in the cogging torque will also have a positive effect on the torque ripple and vibration on the motor. By optimizing studies performed magnet and lamination geometry, new motor geometry has been obtained. Electromagnetic, modal, harmonic analyzes were made this new motor geometry. Analysis results of the new design and the first design were studied comparatively.
