MOTOR DESIGN METHOD, MOTOR DESIGNED BY MOTOR DESIGN METHOD, AND ELECTRIC VEHICLE PROVIDED WITH MOTOR
First Claim
1. A motor design method, comprising:
- 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.
