"An apparatus for determining angular positions of DC motor includes a 
capacitor connected in parallel with the DC motor. The current flowing 
through the capacitor, at any given time, is an AC ripple current responsive 
to a commutation event of the DC motor. The capacitor partially sources the 
motor current ripples during commutation and recharges itself during the 
off-commutation period. Since the number of commutation events per 
mechanical revolution is pre-determined once the DC motor is designed, the 
frequency of the AC ripple currents through the capacitor corresponds to the 
frequency of commutation, and thus a motor position of the DC motor. "
