Therefore, the voltage drop across a motor consists of the voltage drop, due to this CEMF, and the parasitic voltage drop resulting from the internal resistance of the armature's windings.
Since the CEMF is proportional to motor speed, when an electric motor is first started or is completely stalled, there is zero CEMF.
As the motor spins, the CEMF increases until it is equal to the applied voltage, minus the parasitic voltage drop.
At this point, there will be a smaller current flowing through the motor.
This voltage is also generated during normal motor operation.
