Patent ID: 6995493

Claim:
A rotor of a rotating electric machine comprising: a Lundell type core including a field winding, a cylindrical portion wound with the field winding, a yoke portion widened from a position in an axial direction of the cylindrical portion in an outer peripheral direction, and a plurality of claw-like magnetic pole portions constituted to incorporate the field winding, extended in the axial direction from an outer periphery of the yoke portion and bend to be brought in mesh with each other alternately; and a magnet arranged between the claw-like magnetic poles; wherein an outer peripheral face of the field winding and an inner peripheral face of the magnet are made to be proximate to each other to hamper draft between the field winding and the magnet, the field winding wound such that an outermost periphery of the field winding becomes equal to or larger than a diameter of a root portion of the claw-like magnetic pole portions and the inner peripheral face of the magnet and the outermost periphery of the field winding are made to be proximate to each other, and an insulating layer is formed by arranging an insulating member between an outer periphery of the field winding and the inner peripheral face of the magnet and the outer periphery of the field winding is continuously brought into contact with the inner peripheral face of the magnet via the insulating member.
