Claims

[Scope of utility model registration request]

A predetermined number of annular iron core plates having a plurality of salient poles integrally extending from one peripheral edge and a convex portion integrally extending from the other peripheral edge are stacked in a predetermined number with the same shape to form a group, and each group has the aforementioned convex portion. A stator core in which the surfaces of the other peripheral edge are made uneven by stacking the two at different positions, the protrusion extending on the peripheral edge passing through the center of at least one of the salient poles and the center of the core plate. A heat dissipation structure for a stator core, which is arranged asymmetrically with respect to the center line, and each group of laminated core plates is stacked with the front and back reversed.
