20130194704 | PROTECTION CIRCUITS AND METHODS FOR ELECTRICAL MACHINES - An assembly includes an electrical machine connected to a power converter by a three-phase circuit having three conductors, e.g. cables. Each conductor is associated with a switching device such as a contactor or the like that connects the conductor to a common conductor or terminal. In the event of a fault current being developed in the circuit or the power converter, the switching devices are operated to close the fault current and connect together the conductors or the three-phase circuit to provide a full three-phase short circuit. | 08-01-2013 |
20130127391 | ELECTRICAL MACHINES - An ac synchronous electrical machine includes a stator and a multi-phase stator winding that defines a plurality of stator poles. The stator winding has two or more coil groups, each coil group including a plurality of coils for each phase that are received in winding slots in the stator. The stator winding is connected to a power source/sink. The coil groups are connected in series and each coil group is connected to a power source/sink by a respective switch ( | 05-23-2013 |
