Three-section magnetic circuit isolation type bearingless electro-magnetic doubly salient motor and suspension control method

The embodiment of the invention discloses a three-section magnetic circuit isolation type bearingless electro-magnetic doubly salient motor and a suspension control method, and relates to the technical field of bearingless motors. The motor stator comprises a torque module stator, a suspension module stator and a magnetic isolation sleeve, a single-phase torque module stator is composed of four torque module stator iron cores, three-phase torque module stator iron cores are embedded into the magnetic isolation sleeve made of a magnetic isolation magnetic circuit to be fixed, and a torque excitation winding and an armature winding are wound on the torque module stator iron cores. The suspension module stator is composed of four suspension module stator iron cores, the suspension module stator iron cores are embedded into the magnetic shield to be fixed, the suspension excitation windings and the suspension windings are wound on the suspension module stator iron cores, and stable suspension of the rotor can be
