ABSTRACT:
A lamination bundle or stack for a long-stator-linear motor. Each lamination is made of a thin, siliconized metal sheet for the electrical industry with a thickness of between 0.35 to 1.00 mm, and at one end of its narrow side has a recess, and at its opposite end has an extension corresponding to this recess for a positive or form-locking arrangement of the bundles in rows adjacent to each other. Of the teeth laterally defining the grooves of cable windings each end tooth has a width which corresponds to half the width of the adjacent tooth and at its free end is cut at an incline, whereby the inclined cutting line extends from the groove to the end of the narrow side. The laminations are stacked so as to completely cover each other, and have their contacting surfaces glued together over the entire surface area thereof.
