This article focuses on the electromagnetic vibration noise source of fractional-slot concentrated-windings (FSCWs) interior permanent magnet synchronous machines (PMSMs) and its optimal design for vibration noise reduction. First, the analytical model of the radial and tangential force waves of the interior PMSM is constructed, and the harmonic characteristics of the electromagnetic force waves under the action of the stator slotting effect and the rotor saliency effect are obtained. Second, an electromagnetic field finite element simulation model of a 36-slot/24-pole PMSM is established, and the harmonic sources of the main excitation forces are explored in combination with the analytical method. Then, the simulation analysis method of vibration noise with separately loaded radial and tangential concentrated forces is proposed to explore the contribution of different force wave components to the vibration noise. Finally, the main excitation force of the prototype is weakened by using an auxiliary groove, and the auxiliary groove parameters are optimized by sensitivity analysis and multiobjective genetic algorithm, and the effectiveness of the optimization method is verified by simulation and experiment. This study can provide a reference for the low-vibration and low-noise design of the same type of machine.
