Patent ID: 8860277

Claim:
Stator coil segment for an electro mechanical transducer, in particular a generator for generating electric energy from mechanical energy, the stator coil arrangement comprising: a first coil arranged at a first radial position along a radial direction and connected to an input terminal of a first converter to supply electrical energy to the first converter, wherein the radial direction is perpendicular to a rotation axis of the electro mechanical transducer; and a second coil arranged at a second radial position along the radial direction and connected to an input terminal of a second converter to supply electrical energy to the second converter, wherein the first converter and the second converter are distinct devices and operate independently from one another such that failure of one of the first converter and the second converter does not result in failure of the other of the first converter and the second converter; wherein the second radial position is different from the first radial position; and a yoke comprising ferromagnetic material for supporting the first coil and the second coil, wherein the yoke comprises a base portion and a first protrusion protruding from the base portion such that at least a first slot and a second slot are formed, wherein a first portion of the first coil and a first portion of the second coil are arranged in the first slot, and wherein a second portion of the first coil and a second portion of the second coil are arranged in the second slot.
