MOTOR DESIGN METHOD, MOTOR DESIGNED BY MOTOR DESIGN METHOD, AND ELECTRIC VEHICLE PROVIDED WITH MOTOR

摘要

The motor 11 and the electric vehicle 10 provided with the motor 11 designed by the motor design method, the motor design method, have a rotational speed required to achieve a predetermined travel pattern and torque required to achieve the predetermined travel pattern. A first calculation step of obtaining a set, a second calculation step of selecting a motor efficiency corresponding to the rotational speed and torque from one of the motor characteristic curves, and a work amount from the rotational speed and the torque, and dividing the work by the motor efficiency A third calculation step of calculating power consumption, and a fourth calculation step of calculating the total sum of power consumption by repeating the first calculation step, the second calculation step, and the third calculation step over the entire running time.
