Abstract: Because of the increasing demand of small volume and high power density brushless servo motor in the field of weapon system,an integrated design based on multi-physics fields was introduced. The multi-physics fields design of electromagnetic, mechanical, thermal and loss for the high-power density brushless servo motor was analyzed. The product technical scheme was determined by simulation design and motor was produced. A series of performance and environmental tests were carried out according to the national military standard. It is verified that the design method is reasonable and effective, and the product can meet the trial requirements of weapon equipment.

Key words: high-power density, brushless servo motor, multi-physics fields, integrated design
