Abstract
A self-supporting amortisseur winding in the form of a thin copper cage is situated about the solid rotor of a high-speed, permanent magnet synchronous machine in order to keep commutating reactance low. A high-strength wire is wound, with high tension, circumferentially about the cage to counteract the effects of centrifugal force on the cage when the machine is operating.
