Abstract

See full text

A straight line lamination for an electric motor has alternating finger segments and hinge segments to be rollable after windings are installed to form a circular motor stator. The lamination is configured such that inner edges of a back iron region are non-arcuate in shape to provide extra back iron material near the hinge segments for mitigating torque constant roll off.
