Abstract: Aim

ing at the endurance of electric vehicles, complex working conditions and the requirements of high reliability, phase shift 30° dual three-phase PMSM was chosen as the research object. In terms of mathematical model based on space vector decoupling, space vector modulation technology, vector control based on rotor field orientation and senseless control, the existing problems and inferiority of three-phase drive system were compensated, and the solution of high efficiency and fast response and high reliability of dual three-phase motor drive system for electric vehicle was given.

Key words: dual three-phase PMSM, SVPWM, modulation, vector control, senseless control
