摘要: In present monitoring techniques for the detection of broken rotor bars in squirrel cage induction motors, assumption is made that a bar conducts no current. This causes magnetic imbalance, which can then be detected to indicate bar. certain however, large currents are still able flow by means interbar currents. paper deals with effects these have on monitoring. The work shows theoretically and experimentally reduce any imbalance brought about >
