ABSTRACT:
A method for the mass production of squirrel-cage rotors for electric motors includes the step of die casting-in-place rotor bars within the slots formed by stacked steel laminations. The molten metal alloy utilized in the method is high conductivity aluminum. Before introduction of the molten aluminum, the steel laminations are treated in a solution of sodium nitrite, sodium tetraborate decahydrate, and a wetting agent to prevent soldering of the aluminum to the steel.
