Abstract
PURPOSE: To improve locating precision and reduce manufacturing hours by laminating blanked cores on the surface or the undersurface by turns or by shifting at given angles and laminating them by every core or every thickness of several cores.
CONSTITUTION: Stator cores 1, for example when they have four poles, are blanked so that poles 2a∼2d where the teeth 3 are formed at a given pitch on the pole may be arranged at the pitch of 90°. The 2nd, 3rd and 4th cores are laminated so that they may be shifted respectively 90°, 180°, 270° for the 1st core. In this way the angular errors of the stator poles 2a∼2b by the manufacturing errors when the cores are blanked are averaged and the stator poles have the same lamination structure. For a bipolar stator core the angular errors of the stator core is averaged by laminating each side of the core by turns. Cores may be laminated well by every core or by every thickness of several cores.
