The method is used in automated electric excitation for rotational speed measurement of DC motors with independent excitation. According to the method the motor armature is periodically switched off the voltage supply sources and upon reaching the zero-value current, the momentous voltage value of its terminals is measured, which represents the electromotive voltage moment, proportionate to the speed. Then the armature is again switched to the voltage supply sources.
