How to Calculate Back EMF of DC Generator?
Back EMF of DC Generator calculator uses Back EMF = Output Voltage-(Armature Current*Armature Resistance) to calculate the Back EMF, The Back EMF of DC Generator is defined as the opposition offered the supply voltage. The supply voltage induces the current in the coil which rotates the armature. The electrical work required by the motor for causing the current against the back emf is converted into mechanical energy. Back EMF is denoted by E_{b} symbol.
How to calculate Back EMF of DC Generator using this online calculator? To use this online calculator for Back EMF of DC Generator, enter Output Voltage (V_{o}), Armature Current (I_{a}) & Armature Resistance (R_{a}) and hit the calculate button. Here is how the Back EMF of DC Generator calculation can be explained with given input values -> 90 = 150-(0.75*80).
