Electric motor with parallel alignment of the external stator plates

摘要

The motor has closure elements (3) attached to outer stator laminates (2') and tightened together by connection bolts, which traverse a laminated stator core (1) such that the closure elements are pressed at the outer stator laminates. Holders e.g. spacers (5), are attached to the laminated stator core. The outer stator laminates are held at predefined distance from each other and parallel to each other by the spacers in an aligned manner in spite of pressure exerted on the laminated stator core. The holders are formed as hardened impregnating agents i.e. resin. The spacers are formed as bolts or sleeves.
