Interconnection element for connection of stator coils
First Claim
1. An interconnection element for connection of stator coils of a stator of a polyphase rotary electrical machine, the interconnection element comprising a plurality of axially stacked conductive layers including:
- solid base layers, each formed by a solid ring; and
additional layers, each formed by at least two partial rings, each of the partial rings not covering all of a periphery of the stator;
a number of the solid base layers being equal to a number of the additional layers;
each of the conductive layers comprising inner connection lugs for connection of the stator coils, and outer connection lugs for connection to a connected electrical equipment;
the number of the base layers and the number of the additional layers being equal to a number of phases of the polyphase rotary electrical machine comprising the interconnection element.
