An electric motor has 4 rotor bars and runs at 2980rpm. A vibration analysis shows significant radial vibrations at 1x, 2x, 3x and 4x the running speed of the motor. A very large peak shows at a frequency of approximately 12,000cpm. What would you suspect the problem to be and how would you confirm your suspicions?
