Patent ID: 7605517

Claim:
A claw pole type rotating electric machine comprising: a ring yoke portion; first and second claw cores which are formed of a plurality of claw magnetic poles which are disposed at equal intervals on the circumference of the inner diameter side of the ring yoke portion and extend in the axial direction; a stator core formed by meshing of the claw magnetic poles of the first and second claw cores with each other; a stator formed by holding the ring coil on the outer circumference side of the claw magnetic poles in which the stator cores have been meshed; and a rotor positioned via a space in the circumferential direction at the inner diameter side of the stator wherein: the first and second claw cores are formed by compacting of magnetic powder; the radial direction thickness of the claw magnetic pole is 2 mm or more; a flat surface is formed perpendicular to the axial direction at the end extending in the axial direction of the claw magnetic pole; at the claw magnetic pole, a ejection taper in the range of 10 degrees or less with respect to the axial direction is formed as a taper from the base to the end extending in the axial direction; and the ratio of the axial direction length of the claw magnetic pole and the axial direction thickness of the ring yoke portion is no more than 5:1.
