ABSTRACT:
An electromagnetic induction device has coils of a plurality of phases and a duct through which a cooling medium is introduced into the coils to cool them. Guides are provided in the duct so asd to realize a substantially uniform distribution of the cooling medium to all coils. The flow rates of the cooling medium through the coils is substantially uniformallized so that the coils exhibit substantially the same temperature rise. As a consequence, any difference in the life between the coils is substantially eliminated.
