Synchronous machine, in particular generator for a vehicle

摘要

The machine has a stimulation system of individual poles (22,24) in the rotor, esp. claw poles with a common stimulation coil, with pole plate permanent magnets for magnetic stray flux compensation with a holder of two non-magnetic plates (11,11') mounted at the axial ends of the stimulation system on the pole plate (21,23) ends. The holder plates have angled holder strips (13,13') alternately occupying the free space between the poles and carrying the magnets. The strips support the magnets against centrifugal forces, extend over the entire axial direction of the stimulation system and are held by adjacent poles.
