Abstract:
1. An apparatus, comprising: a plurality of coils of a multi-phase machine, each coil from the plurality of coils being associated with a different electrical phase from a plurality of electrical phases of the multi-phase machine; and a plurality of protective elements, each protective element from the plurality of protective elements being associated with a different coil from the plurality of coils, each coil from the plurality of coils being part of an electrical circuit when its associated protective element from the plurality of protective elements is in a first configuration, each coil from the plurality of coils being disposed between its associated protective element and a phase terminal connection associated with its associated electrical phase from the plurality of electrical phases, a protective element from the plurality of protective elements is configured to allow a first amount of current through its associated coil from the plurality of coils when in the first configuration, the protective element configured to allow a second amount of current through its associated coil from the plurality of coils when in a second configuration, the protective element configured to not obstruct current flow through the coils from the plurality of coils that are not associated with the protective element when in the second configuration.
