Claim Text:
1. A motor design method implemented using a computer processing to design a motor dedicated to an electric vehicle, the motor design method comprising: measuring and analyzing a running pattern of the electric vehicle; calculating a set of a number of revolutions and a torque according to the running pattern of the electric vehicle; determining a motor efficiency corresponding to the number of revolutions and the torque with reference to a specification of the motor; calculating a work amount based on the number of revolutions and the torque; calculating power consumption by dividing the work amount by the motor efficiency; producing a sum of the power consumption over an entire running time of the electric vehicle; setting a motor efficiency map, representing the motor efficiency in connection with the number of revolutions and the torque, with the sum of the power consumption minimized; and designing the motor with reference to the motor efficiency map.
