Abstract: As far as the discipline of our motor system is concerned, a series of remarkable achievements has been made in the major equipment building which refers to such fields as energy and power, transportation, high-end manufacture, defense and military industry. However, the continuous development in the field of application makes higher demand on high-quality operational performance of the motor system. The demands include high power density, high reliability, high adaptability, high precision, low emission and multifunction（4H+1L+1M）. Considering applications required in different fields and under adverse circumstances, this paper has raised some common basic scientific problems according to design, implementation, operation and control, and given prospects for development of leading-edge technology of the motor system, this is, extending the boundary of precise physical models for materials and devices, to meet the demand of extreme environments and application conditions; applying an integrated multifunction idea, to combine perception with actuation ability, so as to achieve the high function density and high reliability of the motor system.
