A 12/10 structure bearingless permanent magnet bias switched reluctance motor is composed of suspension pole iron core, torque pole iron core, bias permanent magnet, torque permanent magnet, rotor iron core, suspension pole winding coil, torque pole winding coil and shaft. The bias permanent magnet is embedded between the suspension pole iron core and the torque pole iron core, and the torque permanent magnet is embedded on the teeth of the torque pole iron core. A suspension pole win coil and a torque pole winding coil are respectively wound around that suspension pole iron core and the torque pole iron core; The inside of the suspension pole core and the torque pole core is the rotor core, and the inside of the rotor core is the shaft. The 12/10 structure bearingless permanent magnet biased switched reluctance motor solves the coupling of the suspension pole and the torque pole by biasing the permanent magnet and the air gap, increases the electromagnetic torque by the torque permanent magnet, and improves the torque density.
