Abstract: Driving an electromotor and a brushed electromotor in particular results in ripples in the supply current. The amount of pulses is proportional to the amount of revolutions of the rotor of the electromotor. With a flawless motor, the amount of pulses is the same with each revolution. Flaws of the electromotor, in brushes, rotor, windings and/or other components, results in fluctuations of pulses in the supply current per revolution of the rotor. By comparing an expected amount of pulses to counted pulses and using various physical parameters of the electromotor, various methods may be employed to correct a counted amount of pulses or otherwise provide an appropriate value representing displacement of the rotor of the electromotor. The time between counted pulses may also be used for determining slip of a slip coupling comprised by a drive train to which the electromotor may be coupled.
