Taking the development process of a 3 550 kW 6 kV 6-pole asynchronous motor featured with high efficiency, high power density and low noise as an example, analyzed the approaches and methods to increase the power density and decrease the noise from the aspects of insulation system design, ventilation and heat dissipation design, optimization of electromagnetic design, structure design and manufacturing process, and investigated the influences by related factors on the temperature rise of the motor based on the simulation and test results. Targets were defined for developing this motor of high efficiency, high power density and low noise. Compared with the corresponding parameters of the similar products of the major international electric machines manufactures, test data showed that the defined targets were well achieved of this motor.
