I have recently had some rotors tested(with a core loss tester) and the results showed some high resistance joints between the rotor bars and the short circuit ring(these are brazed joints). I know that these high resistance joints will cause vibration issues, high current draw, and heating issues. I would like to calculate(or estimate)the amount of force or imbalance that would occur from a high resistance joint in a rotor circuit. Any help would be appreciated.
