Back EMF and Its Significance in DC Motor
What is Back EMF? When the armature of a DC motor rotates under the influence of the driving torque, the armature conductors move through the magnetic field and hence emf is induced in them as in a generator. The induced emf acts in opposite direction to the applied voltage V (Lenz’s law) and is known as Back EMF or Counter EMF (Eb). The equation to find out back emf … [Read more...] about Back EMF and Its Significance in DC Motor
