The invention provides a modular double-three-phase permanent magnet synchronous motor device, which comprises a motor shell, a non-magnetic rotating shaft 4, a stator part 1 and a rotor part 2. The cross section of the stator part 1 and the cross section of the rotor part 2 are concentric circles. The stator part 1 and the rotor part 2 are arranged in a space limited by the motor shell. The rotorpart 2 comprises a rotor iron core component 3 and permanent magnet components. There is a radial air gap structure with a preset length between the rotor part 2 and the stator part 1. The permanentmagnet components are adhered to the outer surface of the rotor part 2. The permanent magnet components are uniformly distributed along the circumference of the surface of the iron core. The stator part 1 comprises an E-shaped iron core unit. The E-shaped iron core unit comprises armature tooth components 601 and fault-tolerant tooth components 602. The armature tooth components 601 and the fault-tolerant tooth components
