Liquid-cooled electric machine |
摘要 |
A pressure plate for a liquid-cooled electric machine is disclosed which improves heat removal from the end-face region of the stator lamination stack. The pressure plate is provided with a cooling canal formed by a recess on the surface facing the stator lamination stack which is closed off by a cover plate. The cover plate may be provided with a rib on the surface facing the recess. In one embodiment, a plurality of juxtaposed recesses are provided which extend transversely to the pressure fingers of the pressure plate. The pressure plate is preferably made of stainless, non-magnetic steel, i.e., of austenitic chrome-nickel steel.
