Abstract
A motor driving device and method for a vehicle are provided to adjust and diagnose an air-conditioning motor by sensing an output signal and a current of a feedback sensor. The motor driving device includes a feedback sensor that configured to output a feedback voltage by detecting a rotation angle of a motor. In addition, a controller is configured to generate a substantially constant current that corresponds to an operation state of the motor and determine a driving state of the motor by combining the constant current with the feedback voltage.
