How to Calculate Field Current?
Field Current calculator uses Field Current=Voltage/Shunt field resistance to calculate the Field Current, The field current is the current flowing through the windings in the non-moving part of the motor (which is called the stator, a word derived from “stationary”, or not movable). Field Current and is denoted by If symbol.
How to calculate Field Current using this online calculator? To use this online calculator for Field Current, enter Voltage (V) and Shunt field resistance (Rsh) and hit the calculate button. Here is how the Field Current calculation can be explained with given input values -> 20 = 120/6.
