Assembled structure having an enlarged heat transfer area for heat radiation therefrom
First Claim
1. An assembled structure of a plurality of laminated plates having high thermal conductivity, the assembled structure comprising:
- A plurality of laminated plates, each having with a circular opening at the center of the plate, A plurality of projection parts extend from an outer periphery of the plate toward the circular opening for forming stator magnetic poles, The plurality of laminated plates, each having a length and a shorter width and notches at the edge on the center line of the direction of the length, and each being laminated alternatively with an adjacent abutting plate such that the length of one plate is perpendicular to the width of the adjacent plate to form a shape of a cross, with the excess length of one plate overhanging beyond the width of an adjacent plate, the overhanging portions serving to dissipate heat from the plates.

Abstract
This invention is related to an assembled structure of laminate plates for radiating heat therefrom wherein there are formed a plurality of slits between peripheries of the plates around the laminated assembly in such a manner that the plurality of laminated plates, each having a length and a shorter width and notches at the edge on the center line of the direction of. the length, and each being laminated alternatively with an adjacent abutting plate such that the length of one plate is perpendicular to the width of the adjacent plate to form a shape of a cross, with the excess length of one plate overhanging. beyond the width of an adjacent plate, the overhanging portions serving to dissipate heat from the plates.
