In order to save energy and reduce emissions, improve the ecological environment and achieve sustainable development, the research and development of electric vehicles has become a common consensus in all countries in the world. As the core component of electric vehicles, the requirements for drive motors are getting higher and higher. The control strategy of the dual-stator motor is based on the mature vector control method of the traditional PMSM. The two sets of three-phase windings are transformed at the same time by rotating coordinate, and the vector control under the dual synchronous rotating coordinate is realized through separate decoupling; the control system uses TMS320F28335 as the control core, equipped with The dual stator motor vector control system makes full use of chip resources to realize the functions of rotor position detection, two-winding current and voltage acquisition and IGBT drive at the same time to complete the torque control of the two stator windings. It is verified by experiments that the control system meets the requirements of electric vehicle power system, with simple structure and strong practicability.
