Abstract
A motor design method, a motor () designed by the motor design method, and an electric vehicle () provided with the motor () include a first calculation step of obtaining a set of a number of revolutions required to achieve a predetermined running pattern and a torque required to achieve the predetermined running pattern, a second calculation step of selecting a motor efficiency corresponding to the number of revolutions and the torque from any one of motor characteristic curves, a third calculation step of obtaining a work amount from the number of revolutions and the torque and obtaining power consumption by dividing the work amount by the motor efficiency, and a fourth calculation step of obtaining a sum of the power consumption by repeating the first calculation step, the second calculation step, and the third calculation step over the entire running time.
