Abstract:
Redundant winding connections for multiphase electric machines are disclosed. According to one aspect, a multiphase machine having redundant winding connections includes: a first set of N coils operating as a first winding group, wherein each coil in the first winding group operates at a different phase from the other coils in the first winding group and wherein N is an integer greater than three; a second set of N coils separate from the first set and operating as a second winding group, wherein each coil in the second winding group operates at a different phase from the other coils in the second winding group and wherein the failure of one of the coils in the first winding group does not affect the function of the second winding group.
