PROBLEM TO BE SOLVED: To prevent ununiformity in a delivery amount of a magnetic flux at an air gap and to prevent reduction in efficiency, in a claw pole type rotary machine.SOLUTION: A stator core of a stator 1 comprises U, V, and W-phase teeth 3b, 4b, and 5b each having a claw shape, and is a three-dimensional magnetic flux type that flows a magnetic flux in a radial direction and an axial direction. The stator coil is constituted of two-wire U and W-phase coils 7 and 8, provided annularly and sandwiched by the U, V, and W-phase cores 3, 4, and 5 in the axial direction. With respect to a surface of a rotor 2 in the U, V, and W-phase teeth 3b, 4b, and 5b, an air gap α at a side close to a root part is larger, and the air gap α at a side apart from the root part is lower. Thereby, even in a case of a claw pole type, a delivery amount of the magnetic flux at the air gap α can be equalized in the axial direction, and the motor efficiency can be improved. |
