description The invention discloses a multi-order vector space decoupling control method for a single-winding bearingless permanent magnet motor, and aims to solve the problem that a traditional single-winding bearingless permanent magnet motor is complex in structural algorithm, and a simple two-pole six-slot six-phase centralized double three-phase connected stator winding structure is adopted. And three vector spaces with different orders are constructed according to the structure, and the decoupling of the torque, the suspension force and the triple frequency harmonic of the motor can be realized by performing vector control in the three spaces according to a specific modulation rule. According to the invention, a simple six-slot six-phase motor structure is adopted. The stator winding adopts short-distance winding, and can generate a relatively large second harmonic magnetic field for generating suspension force; the double three-phase method can physically eliminate triple frequency harmonic waves. Therefore, the s
