Brazing of the rotor

The rotors for the Melotte submersible motors are produced from copper rotor bars (instead of aluminum ones) in order to obtain maximum motor efficiencies. The heat released when brazing these rotor bars to the copper short circuit rings, is used to shrink the stainless steel shaft-ends in to the centre shaft of these rotors. This manufacturing method enables Melotte to simply adjust the material selection for the rotor shaft end, thus selecting the correct material quality for each application, based on your local water quality.
