STATOR LAMINATION FOR AN ELECTRIC MOTOR

摘要

The present invention refers to a stator lamination plate (10) for an electric motor that comprises a central hole (20), a plurality of grooves (30) spaced around the hole (20), and a plurality of teeth (50) formed between two consecutive grooves (30). The hooks (35a, 35b, 35c, 35d) formed between two sides of each groove (30e and 30a, 30e and 30b, 30b and 30d, and 30c and 30a) comprising rounding radii and angles formed by the tooth sides are acute angles. The teeth (50) have two non parallel sides (30a, 30b, 50a, 50b) ending towards the central hole (20) in pole shoes (30c, 30d).
