Production manner of the lamination core for the rotary electrical machinery and appliances, laminating the fairing device and the rotary electrical machinery and appliances null electromagnetic steel sheet

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing and a device for fairing the stacked core for a dynamo-electric machine which is superior in frame pressure bonding work efficiency by preventing occurrence of burrs, and a fairing device, and the dynamo-electric machine.;SOLUTION: The peripheral face of a stacked core is faired by pushing into a pair of outer molds 5 and 6, in a direction where they come close to each other in the axial direction from both ends of a stacked core 7, against the stacked core 7 which is caught with catching members 2 and 3, thereby covering the stacked core 7. This method can solve the conventional problems, such as occurrence of 'burrs' incidental to the fairing of the stacked core or the pressure bonding work of a frame causing difficulties.;COPYRIGHT: (C)2001,JPO
