Given: V = L di/dt I(t) = I(t0) + 1/L × ∫ V(t) dt Rearrange: (L/V) × (I(t) - I(t0)) = dt Using the formula: PWM on-time = (L/V) × 2 × (IDESIRED - ISTART) For ...

For example, the current at a load of 300 mNM is about 65 A, and the speed with 12 V applied is 10,200 rpm. If the load was reduced to 100 mNM, then a current of 20 A would be demanded and the ...
