Abstract:

A rotor analyzer for an induction motor or generator checks and quantifies the integrity of a rotor that is not currently installed within its stator. The analyzer includes an electromagnetic coil that exposes the bars of a rotor to a pulsating magnetic field to induce a current through the bars. At the same time, the rotor is slowly rotated to sequentially expose each bar. A magnetic field created by the induced current in the bars induces an analog signal within a search coil. The analog signal is converted to digital and inputted to a microprocessor system. The system interprets the input data and manipulates it to provide a clear, understandable indication of the rotors condition, such as the relative impendence of each bar. The system also determines how many bars are within a rotor having an unknown number of bars.
