<p>PURPOSE:To presume an abnormality of the operational motion of a motor by detecting an operational current which runs to the motor, and send an alarm by integrating inside condition-detecting protective switches of which the detection result cannot be taken out to the outside, in a compressor. CONSTITUTION:This motor abnormality-detecting method is for an air- conditioning device wherein inside condition-detecting protective switches 12, 14, 16 to detect an abnormality of the operation condition of a motor CM of a compressor are arranged in the compressor 10, and the detecting result of the inside condition-detecting protective switches 12, 14, 16 cannot be taken out to the outside of the compressor. For this method, an operational current of the motor is detected, and an operational abnormality of the motor CM is presumed by a value of the operational current. By this method, even when the detection result of the inside condition-detecting protective switches cannot be taken out to the outside of the compressor, an operational abnormality of the motor can be presumed by the value of the operational current.</p> |
