Abstract
An apparatus for diagnosing abnormal operation of a rotor. The apparatus includes a first sensor provided around a shaft in order to detect vibration occurring while the shaft provided in a rotor axially rotates, a second sensor to generate a periodic pulse signal over time whenever the shaft rotates once, and a controller to determine an operation state of the rotor by receiving signals detected by the first and second sensors. When an aperiodic pulse signal is detected in the rotor, the controller determines a position of the rotor at which the aperiodic pulse signal is generated, and a display indicates the position of the rotor in which the aperiodic pulse signal is generated, according to information calculated by the controller.
