Direct winding cooling for closed rotating or linear electric machine, involves providing winding and groove including winding heads in case of liquid medium with liquid trap sealed to air gap

摘要

The method involves winding each coil (3,4) about a tooth (6,7) with a radial cooling gap (8) between the coils on adjacent teeth, arranging a radial groove spring (1) in the gap and providing the winding and the groove including the winding heads in the case of a liquid medium with a liquid trap sealed up to the air gap.
