Abstract: The present invention relates to a method for driving a permanent magnet synchronous motor. A method for driving a permanent magnet synchronous motor includes a step of generating a d-q axis stator magnet flux reference by using input which includes the toque reference of a motor, the speed of the motor a DC voltage, a step of calculating a stator magnetic flux level reference and a load angle, and a step of generating the toque reference of the motor by using the calculated stator magnetic flux level and the load angle. The present invention obtains the trajectory of an optimal magnetic flux vector and allows the permanent magnet synchronous motor to operate with maximum toque, thereby operating even in a specific range which exceeds an existing range.
