In this paper, a multi-objective optimization strategy is proposed for the design of high-density low-noise motors. The approach considers efficiency and computational accuracy and uses a wide-frequency-domain multi-operating-condition electromagnetic vibration source as the objective function. The first step is to identify the wide-speed multi-operating-condition vibration source of the motor using the unit-force-wave response method. Then, a multi-objective optimization model of high-density low-noise motors is established by combining electromagnetic design objectives to create a mapping relationship between the electromagnetic noise source and the structural parameters. This method optimizes a 48-slot 8-pole IPMSM for suppression in electric vehicles. The amplitude of the vibration source of the prototype is reduced by 80.73% and 85.48%, respectively, while the average torque remains unchanged. The vibration acceleration of the motor is significantly suppressed under the wide frequency domain multi-operating conditions. This paper provides technical support and design references for engineering applications.
