Electric motor e.g. synchronous motor, has at least one ring of magnetisable material mounted on magnetisable rotor and magnetized so that axial profile of magnetization has inclination angle

摘要

The electric motor has a stator and a rotor (1), where the rotor is made of magnetisable material, and at least one ring of magnetisable material (2) is mounted on the rotor and magnetized so that axial profile of the magnetization has an inclination angle. AN Independent claim is also included for the following: a method of manufacturing an inventive device.
