Web12 okt. 2024 · Let the flux ( φ) of the motor is decreased by decreasing the field current. The decrease in flux will drop the back emf (E b = N φ /K) instantly, causing the armature current to increase because the voltage equation of DC motor is given by I a = (V – E b )/R a. Thus, a small reduction in flux will cause the armature current to increase ... WebBack EMF vs RPM on the 106-002 DC Motor. We can calculate the back EMF by measuring the current in steady state with no load and comparing it to a calculated …
