A torque map generation system includes a motor, an inverter that drives the motor, a controller that controls the inverter, a torque sensor coupled to the motor, a power analyzer coupled to the torque sensor and a torque map generator that measures a current vector value of the motor by switching a MTPA (Maximum Torque Per Ampere) method and a square wave method based on a voltage utilization ratio of the inverter, wherein the torque map generator utilizes a measurement result by the MTPA method when the torque map generator uses the square wave method.
