1. An apparatus for diagnosing motor performance of a vehicle, comprising:
a memory configured to store program instructions; and a controller configured to execute the program instructions, the program instructions when executed configured to: instruct validity diagnosis of a motor; detect a D axis voltage (vd) and a Q axis voltage (vq), which are input to the motor in response to a diagnosis instruction from the diagnosis instructing unit; collect angular velocity (ω) of the motor in response to the diagnosis instruction; calculate a magnetic flux (ψF) of the motor based on the D axis voltage, the Q axis voltage, and the angular velocity; and determine validity when the magnetic flux is within a predetermined range. |
