FRAME BODY FOR ROTOR FOR AXIAL GAP TYPE MOTOR, ROTOR FOR AXIAL GAP TYPE MOTOR AND METHOD FOR MANUFACTURING ROTOR FOR AXIAL GAP TYPE MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a frame body for a rotor for an axial gap type motor capable of reducing a disposal work for disposing the frame body for the rotor to a rotating shaft by suppressing the number of the parts of clamping parts such as bolts.;SOLUTION: The frame body 10 includes: an external frame 3 partitioned into a plurality of first approximately circular arcs 3a and hinge-connecting parts among ends 3b among the mutually adjacent first approximately circular arcs; and an internal frame 5 divided into a plurality of second approximately circular arcs 5a corresponding to each of the first approximately circular arcs. The frame body 10 further includes a plurality of connections 7 mutually connecting the mutually corresponding first approximately circular arcs and second approximately circular arcs. (i) The recessed side faces 5b of each second approximately circular arc form a center hole 5f penetrating the rotating shaft, and (ii) a plurality of regions 9 fitting each magnetic material respectively are predetermined by the external frame, the internal frame and the connections under the state mutually connecting the ends 3b2 of each first approximately circular arc at both ends of the external frame and displaying the external frame and the internal frame in an annular shape.;COPYRIGHT: (C)2010,JPO&INPIT
