Permanent magnet synchronous machines with magnetic flux regulation

摘要

An electrical machine (100) has a permanent magnet component (10) and a winding armature (20). The permanent magnet component (10) is spaced apart for the winding armature (20). A field excitation winding is (18) operative connected to the permanent magnet component (10). The field excitation winding (18) is configured to selectively intensify and de-intensify the magnetic field of the permanent magnet component (10) for control of magnetic flux in the electrical machine (100).
