Patent ID: 10574108

Abstract:
A winding arrangement method for a radial gap-type motor in which a three phase winding wound in a distributed winding form is inserted in slots of a stator includes: a coil forming step that, for each phase, forms a coil wound for each one pole pair; a coil group forming step that, for each phase, forms a first coil group by connecting odd-number-th coils along a direction of rotation via crossover wires, and forms a second coil group by connecting even-number-th 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, 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 neutral point at the connection point.
