FAULT-TOLERANT ELECTRICAL MACHINE

摘要

An electrical machine with a rotor 112 or the stator 104 comprising a plurality of discrete field modules 102, and the other one of the rotor 112 and the stator 104 comprising a plurality of armature coils 114 connected to different power converters. Each field module 102 comprises one or more field coils 106 which can be activated independent of the field coils 106 of the neighbouring field modules 102. When at least one of the field coils 106 is inactivated, e.g. because of a defect, each of the power converters is allowing less power to pass through when an armature coil 114 connected to it is moving over an inactivated field coil 106, and more power to pass through when the armature coil 114 connected to it is moving over an activated field coil 106.
