is impossible to secure uniformacceleration in a car because the counter electromotive force of themotors increases with the speed and cuts down the current. If thecurrent could be kept uniform it would be possible to apply a con-stant gross accelerating force. Even then the net accelerating… … Fig. 130. Acceleration Curves The problem is now to determine a curve between time andspeed for a given equipment by combining the principles alreadycarefully studied separately. Acceleration Curves. Referring now to the curves of the motor.Fig. 47, we note that for every current there is a…
