ARMATURE STRUCTURE OF DYNAMO-ELECTRIC MACHINE, AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To curtail the waste of material and downsize a dynamo-electric machine. SOLUTION: A stack 21 is made by stacking a plurality of magnetic thin plates 30 in each of which a required number of circular element boards 31 having tooth pieces 31b on the side of inside periphery are coupled with one another by couplings 31 a at the edges on outside periphery side, and a bobbin 25 where a coil 24 is wound is installed to each of plural teeth 22 made by the stacking of each tooth piece 31b, and each coil 24 is wired to form an armature coil. Then, a stack 21 is formed circularly by welding both ends of each magnetic thin plate 30 so as to form an armature core.
