The present invention provides a winding modular permanent magnet motor, including stator, rotor and air gap. The stator consists of a stator core and armature winding, permanent magnet and magnetic. Open slots of a stator core, facing the air gap slot interval equipped with a permanent magnet and magnetic gear, permanent magnet and magnetic teeth arc length were tau. The magnetization direction of the permanent magnet is the same. The positive and negative windings of each single effective coil are arranged in the adjacent two large slots. The N coils in the same phase are wound in adjacent 2N large grooves according to the winding method of a single coil. The teeth between the slots in the same phase are all the first teeth. The teeth between the different phase windings are second teeth. The rotor core and the gap between the adjacent rotor core, the arc length spacing is 2 t. Air gap is formed between stator and rotor. The motor adopts the modular structure design of in-phase winding, simplifies the winding structure, shortens the length of winding end, improves the utilization ratio of winding and increases the torque density.
