WebJun 6, 2016 · Let us assume the speed of the DC motor or wheel is x or x m/s in this case. If the ON pulse lasts 3 ms and the OFF pulse lasts 1 ms, the speed of the wheel or DC motor would be greater than x or x m/s as it is getting more overall current in the same period of time. Feeding a constant current is not advisable to drive a DC motor. WebBy substituting equations 3. and 4. (torque and speed, section 2.1) into equation 2. (power, section 1.3 ), we see that the power curves for a D.C. motor with respect to both speed and torque are quadratics, as shown in equations 5. and 6. From these equations, we again find that maximum output power occurs at = ½, and = ½ repectively.
