Synchronous motor or generator rotor manufacture

The rotor manufacture has a rotor body (13) fitted with a number of permanent magnets (17) adjacent the airgap between the rotor and the stator. The rotor body is formed from a number of separate soft magnetic elements (11) for providing a magnetic feedback circuit, spaced apart in the rotor periphe...

Beschreibung
Zusammenfassung:	The rotor manufacture has a rotor body (13) fitted with a number of permanent magnets (17) adjacent the airgap between the rotor and the stator. The rotor body is formed from a number of separate soft magnetic elements (11) for providing a magnetic feedback circuit, spaced apart in the rotor peripheral direction. Each rotor body element may be provided as a segment or a circular sector with its curved side facing the airgap, assembled from a number of soft magnetic lamella plates.
