ROTOR FOR AXIAL-GAP-TYPE ROTATING ELECTRIC MACHINE, AXIAL-GAP-TYPE ROTATING ELECTRIC MACHINE, METHOD OF MANUFACTURING THE ROTOR, AND METHOD OF MANUFACTURING THE AXIAL-GAP-TYPE ROTATING ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To prevent thermal demagnetization of a permanent magnet or the loss of magnetism in the permanent magnet, by blocking or reducing heat conduction to the permanent magnet that constitutes a rotor, in assembling the rotor of an axial-gap-type rotating electrical machine by welding.;SOLUTION: The rotor 14 includes a frame 26 welded to a first pressing member 22, a field part 20 stored in a field part storing hole 24, a second pressing member 32 which fixes the field part 20 within the field storing hole 24, a thermal resistance part 100 which blocks or reduces heat conduction from a weld zone S1 to the field part 20, and a thermal resistance part 102 which blocks or reduces heat conduction from the weld zone S2 between the first pressing member 22 and the frame 26 to the field storing hole 24.;COPYRIGHT: (C)2010,JPO&INPIT
