METHOD FOR CONTROL OF ELECTROMOTIVE COMPRESSOR

摘要

PURPOSE: A method for controlling an electromotive compressor is provided to rapidly verify the malfunction of a motor or the abnormality of an inverter by measuring the three-phased current of a driving motor. CONSTITUTION: Power is applied to an air-conditioner(S110). A micro-current is applied to the driving motor of a compressor in order to detect a three-phased current using a sensor(S120). The abnormalities of an inverter or the driving motor are verifies based on the sum of the three-phased current values(S130). The sum of the three-phased current values is in an error range, the compressor is normally operated or driven(S140). The sum of the three-phased current values is out of the error range, an error message is outputted(S160).
