ABSTRACT:
An abnormality detection apparatus and an abnormality detection method are provided. In a motor abnormality detection apparatus for detecting an abnormality of a motor, a current measurer measures the current flowing through the motor. A voltage measurer measures the voltage applied to the motor. A motor state detector detects the operation state of the motor. A current estimator estimates the current flowing through the motor based on the measured value of the voltage measurer and the detection result of the motor state detector. An abnormality detector detects an abnormality of the motor based on the measured value of the current measurer and the estimated value of the current estimator. The motor abnormality state detection method includes the steps of measuring the current flowing in the motor and the voltage applied to the motor; detecting the operation state of the motor, estimating the current flowing through the motor based on the measured voltage and the detected operation state, and detecting an abnormality of the motor based on the measured current and the estimated current. The abnormality detection apparatus and an abnormality detection method which can detect whether the current measurer itself operates abnormally to accurately detect an abnormality of the motor, and detect the abnormality of the motor due to the abnormality of the current measurer and the poor connection between the motor and the power source.
