High loading capacity electric machine - uses stator with at least one cavity for housing coolant medium that changes from solid to liquid state

摘要

The high load-carrying capacity electric machine comprises a stator, rotor and cooling unit, and is designed for rapid load build-up capacity without over-heating developing. The machine stator has at least one tightly sealed space (116,123) filled with a heat retaining medium that changes from a solid into a liquid when a temp. lying within the working temp. range of the machine is reached, the transition being attained by intake of heat.
