What is Back Electro-motive Force?

BEMF is the voltage generated during the operation of a rotating machine (a generator or a motor). When voltage (an electro-motive force) is applied to a motor's armature, it begins to rotate, and the magnetic field generates an amount of electrical resistance. 

This "kick-back" or counterforce is called Back Electro-motive Force or Back-EMF ( BEMF ).
