Abstract
An error determining apparatus of a driving device including a motor and a 3-phase inverter supplying power to the motor through a 3-phase cable may include a resistor provided in each phase of the 3-phase cable, a voltage sensing device sensing voltage of opposite ends of the resistor by a current flowing into the resistor, and a sensing controller determining whether the resistor is faulty or whether the 3-phase cable is opened, based on the sensing voltage of the voltage sensing device and a 3-phase current sum of the 3-phase inverter.
