Electric motor with auxiliary axial movement has magnetically isolating openings in insides of associated compact plate packet cylindrical surfaces alongside each other in working position

摘要

The electric motor has a rotor (3) with limited axial movement relative to a stator (2) in a working position (X) and axially movably engaged compact plate packets (4a,4b) for the stator and rotor. Magnetically isolating openings (6) along the insides of the associated cylindrical casing surfaces (5a,5b) of the compact plate packets are arranged alongside each other in the working position.
