Distributed winding radial gap-type motor and winding arrangement method therefor

A winding arrangement method for a radial gap-type motor in which an n-pole-pair (n is integer times of 4) three phase winding wound in a distributed winding form is inserted in slots of a stator, wherein the method is characterized by comprising:

• a coil forming step that, for each of the three phases, forms coils wound for each one pole pair;
• a coil group forming step that, for the each phase, forms a first coil group by connecting odd-number-th coils of the coils along a direction of ration via crossover wires, and forms a second coil group by connection even-number-th coils of the coils along the direction of rotation via crossover wires;
• and
• a parallel-connecting step that, for each phase, connects the first coil group and the second coil group at one end in a manner such that the first coil group and the second coil group are in a parallel-connected relationship to each other, to form a current input side lead wire at the connection point, and connects the first coil group and the second coil group at the other end, to form a point of the connection as a neutral point.
