Apparatus for soldering the winding to the commutator of an electric machine

摘要

Apparatus for soldering the winding of armatures of electrical machines to the collectors thereof. The apparatus includes a device for gripping, displacing and fixing the armature with the collector, a single-phase magnetic-hydrodynamic pump with metal conduit and a bath with molten solder and heaters. The magnetic core of the single-phase magnetic-hydrodynamic pump is embraced by a metal conduit disposed underneath the bottom of the bath, and the inlet of the metal conduit is connected to the bottom of the bath, while its outlet end is rigidly connected to a casing fastened to the bottom of the bath. To the bottom of the casing there is pressed by means of an easily releasable joint a changeable nozzle unit. When it is necessary to solder a collector with a diameter different from the previous one, the changeable nozzle unit is taken out of the apparatus and new one of a size corresponding to that of the collector to be soldered is inserted in the apparatus.
