Title: Device and method for detecting abnormality
Inventor: SATO TAKAHIRO
IPC: H02P29/024
Filed: 2021-03-08
Abstract: To detect an abnormal state of a motor with higher accuracy compared with the conventional art.SOLUTION: A device for detecting an abnormality comprises a signal processing unit that detects an abnormal state of a motor on the basis of a current or a voltage supplied from a power supply to the motor. The signal processing unit performs frequency analysis of data of the current or the voltage to calculate a predetermined frequency width with reference to a reference drive frequency related to the maximum peak value of frequency analysis results. When the calculated frequency width is equal to or more than a predetermined threshold, the signal processing unit determines that a rotational speed of the motor changes, and when the calculated frequency width is less than the predetermined threshold, determines that there is no change in the rotational speed of the motor, thereby detecting the abnormal state of the motor. Here, the frequency width is a difference between a pair of frequencies corresponding to a pair of values decreased by a predetermined value from the maximum peak value, such as a half value width that is a difference between a pair of frequencies corresponding to a pair of values decreased by a half of the value from the maximum peak value.SELECTED DRAWING: Figure 1
