  • Apparatus for brazing rotor bars to end rings of a rotor for an asynchronous AC motor
    Patent number: 5398404
    Abstract: A method for brazing end rings to rotor bars for a squirrel cage rotor assembly comprises assembling the rotor in a brazing fixture with a braze shim between the rotor bars and the end rings; preheating the rotor and brazing fixture to a temperature that is below the aged temperature of the rotor bars and end rings and which is sufficiently high so that the difference in thermal expansion of the rotor bars and brazing fixture applies a predetermined amount of pressure on the brazing joint such that after the joint is brazed and has cooled, a braze filler having a predetermined thickness inches will bond the rotor bar end faces to the end ring, and brazing each joint to bond the rotor bar end faces to the end ring.
