Colling of high-voltage rotating electric machine

Colling of high-voltage rotating electric machine

The invention relates to cooling of high-voltage rotating electric machines, and involves direct contact cooling of the magnetic cores (1A, 2A) and of at least part of the solidly insulated windings (1B, 2B) by the same kinetic-energy carrying medium (11) that drives or is driven by the rotating ele...

description The invention relates to cooling of high-voltage rotating electric machines, and involves direct contact cooling of the magnetic cores (1A, 2A) and of at least part of the solidly insulated windings (1B, 2B) by the same kinetic-energy carrying medium (11) that drives or is driven by the rotating electric machine (10) as the medium, such as water or air, flows into contact with and past the core and the winding. This generally means that the rotating electric machine (10) is arranged at least partly within the flow of the medium (11) that drives or is driven by the rotating electric machine, and that the rotating electric machine (10) and the whole energy conversion system is constructed as an open system allowing the medium (11) to flow into contact with the magnetic cores (1A, 2A) and the solidly insulated windings (1B, 2B). According to another aspect of the invention, the spinning member of a rotating machine is constructed as an integrated combination of an electromagnetic rotor and a turbine.
