Abstract :
Research has shown that it is possible for currents to flow in a broken rotor bar of a squirrel cage induction motor by means of interbar currents. Such research dealt only with single-cage motors. Further work was necessary when considering double-cage motors. This paper proves theoretically and experimentally that interbar currents also exist in double-cage motors. The influence of interbar currents on the current distribution around the broken bar is also shown
