Abstract

The flat collector plate is for the rotor of an electric motor. Its manufacturing technique minimises some of the processes normally required such as skimming off the surface after moulding the conductors within the insulating body material and cutting back the insulation between conductors to remove short-circuiting material resulting from the skimming process. Mfr. consists of a series of individual stages commencing with cutting radial strips on the basic disc. The centre hole used for setting up is then opened up and the strips previously formed are folded back under the disc. Further strips cut between the full radial ones are similarly formed and folded over the disc perimeter.
