The induced voltage in an ac or dc motor that opposes the applied voltage.

Helpful?

Counter electromotive force. Voltage induced in an inductor or the armature coil of a motor by the flow of changing current through the inductor or armature. The polarity of this voltage is opposite (counter) to that of the change of current. Also called back voltage.

Helpful?

A voltage produced by a transformer that has the opposite polarity of the voltage that caused it. Often referred to as kick emf.

Helpful?

The voltage generated within a coil by a moving magnetic field cutting across the coil itself. This voltage is in opposition (counter) to the moving field that created it. Counter emf is present in every motor, generator, transformer, or other inductance winding whenever an alternating current flows.
