Back electromotive force is a voltage that occurs in electric motors where there is relative
motion between the armature of the motor and the external magnetic field and is also a
parameter used to evaluate the strength of the permanent magnets of the shaft. One
practical application is to use this phenomenon to indirectly measure motor speed as
well as estimate position.
