Abstract:
1. A rotor for a multipolar synchronous rotating machine comprising: a plurality of salient poles, each salient pole including a polar body and being surrounded by an induction coil comprising a plurality of layers of coiled wire, said plurality of salient poles being integral with a ring, said ring comprising an aperture situated between two salient poles suitable for cooling said rotor; a plurality of spacers such that each spacer of said plurality of spacers creates a first spacing between two successive layers of coiled wire of said plurality of layers for the circulation of coolant between each layer of coiled wire of said plurality of layers, said rotor comprising a second spacing between said polar body and each layer of coiled wire of said plurality of layers for the circulation of said coolant between said induction coil and said polar body, said plurality of layers of coiled wire being radially maintained with a support sheet, said support sheet comprising at least one conduit suitable for circulating a coolant from said aperture towards said second spacing; said first spacing and said second spacing being arranged such that the coolant circulates from said second spacing towards said first spacing between two layers of coiled wire.
