Abstract
A fault tolerant synchronous machine has a stator with a core containing a plurality of phase windings, a rotor supported for rotation within the core, and a non-magnetic sleeve affixed to the stator and disposed in the space between the stator and the rotor and having a plurality of slots extending parallel to the axis of the rotor and positioned to receive high permeability inserts for shunting the flux paths of faulty stator windings to permit low power operation of a synchronous machine having faulty stator windings.
