     Total force
The total force is the summation of all the forces affecting the motor.

                             TTE = RR + Fd + FA                    (7)

TTE = Total tractive effort

                      148.2 + 17.77 + 66.708 = 232.678 N

 Power

                                     P = FT v     (8)

                                               η

P = engine power (W)

FT = total forces acting on the car

v = velocity of the car (m/s)
η = overall efficiency in the transmission, normally ranging 0.85 (low gear) - 0.9 (direct

drive)

At speed 40 kh

                             232.678 x 11.11 / 0.75 = 3446.76 W

The selected motor is Golden Motor with 48 V and 5000 W.
