Abstract: PURPOSE: A method for detecting the disconnection of a power cable of a motor is provided to prevent lethal damage by accurately detecting the disconnection of the power cable in the initial stages. CONSTITUTION: A controller detects current supplied to each phase of a motor according to the switching of an inverter. The controller detects the drive speed of a motor(S102), whether the drive speed exceeds the fixed reference speed or not is determined(S103). If the drive speed of the motor exceeds the fixed reference speed, whether the control current for motor drive exceeds the reference value of the maximum current or not is determined(S104). If the control current for the motor drive exceeds the reference value of the maximum current, the disconnection of the power cable connecting an inverter and a motor is activated(S105). Whether the phase current supplied to a motor is lower than the second reference value of the current reference or not is determined(S106). If the phase current exceeds the second reference value, the power cable is determined as the normal state.
