Rotor for electrical machine has ring device with magnet holding elements flanking rotor ring, magnets on surfaces facing rotation axis, fixed to rotor ring, subject to radial rotation forces

摘要

The device has a rotor ring (3) with permanent magnets (6) distributed on its circumference and a ring device (R) for securing the magnets against centrifugal forces of rotation. The ring device has holding elements (9) flanking the rotor ring and the magnets on the lateral surfaces facing the rotation axis, fixed to rotor ring and subject to radial forces during rotation.
