BLDC Motor Back EMF Explained

This article primarily explains what's back EMF in Brushless DC motors (BLDC), which are used where there are limitations in use of the brushed DC motor (BDC). The brushless DC motor(BLDC) is one which operates without any brush for supplying DC voltage to the rotor armature which is necessary in order to make it as electromagnet as the operation of DC motor depends on the attraction and repulsion principles of magnetism.
