Abstract

Apparatus for soldering the winding to the commutator of a rotor of great weight of an electric machine. The apparatus has a vessel containing a bath of molten solder and electric resistance heaters, a single-phase magneto-hydrodynamic pump consisting of a first magnetic core disposed beneath the vessel, the first magnetic core being supported from below and surrounded by a winding and solder stream-formation unit made of ferro magnetic material which is concentric with the first magnetic core. The bottom wall of the vessel is disposed on the first magnetic core, and within the vessel and on the bottom thereof there is fastened rigidly an additional, second hollow magnetic core, which is a continuation of the first magnetic core, while a tubular casing which is concentric with the second magnetic core, and which is of stepped shape, seats with its external step on the additional, second hollow magnetic core. The weight of a rotor placed in the upper end of the case of the tubular casing is transmitted to the second magnetic core from the tubular casing, through the bottom walls of the vessel, to the first magnetic core, and then to the external support for the first magnetic core.
