ステータ及び電気機械
Document Type and Number:
Japanese Patent JP2005539477
Kind Code:
A
Abstract:
The method for making a stator includes making individual strip-shaped laminas (15) for it; stacking the laminas (15) to form a stator core (13) with grooves (18) on one side extending through the core; producing a subassembly by inserting a stator winding (17) into the grooves (18); bending the subassembly to form a cylindrical cavity so that the grooves (18) end in the cavity and connecting two ends (23) of the stator core (13) to each other by a welding seam (20) to maintain this configuration. To produce a welding seam of sufficient strength which does not exert excessive influence on magnetic properties, the welding seam depth (TS) is given by TS=0.5 mm*(Hyoke/mm−1)±ΔTS, wherein Hyoke is yoke height and ΔTS is a tolerance value. An electric machine including the stator made by this method is also described.
