APPARATUS FOR SATURATING AND HARDENING THE STATOR WINDING RODS OF HIGH VOLTAGE ELECTRIC MACHINES

摘要

Each of a plurality of frames has frame wall portions defining the groove dimensions of a corresponding rigid rod wound with the insulating tape and substantially in its final configuration and additional bending frame wall portions for fixing the curved winding end portions of the rod in the junction between the straight groove portion and such end portions. A corresponding one of the rods is inserted into each of the frames thereby preparing the frames and the rods for a saturating operation. A carrier for a plurality of the rods and their frames are combined into a hardening unit. An additional frame is provided for all the rods in common at each surface at each end of the hardening unit for fixing the winding end portions and rod ends thereby preparing the frames and the rods for a hardening operation.
