... Philips Semiconductors Brushless DC motor and VCM drive circuit with speed control If the amount of EMF generated is insufficient, then the motor will move one step only and will oscillate in its new position. The amplitude of the oscillation must decrease sufficiently before the arrival of the next start pulse, to prevent the pulse arriving during the wrong phase of the oscillation ...

... Philips Semiconductors Brushless DC motor and VCM drive circuit with speed control The Timing Capacitor (CAPTI) Capacitor CAPTI is used for timing the successive steps within one commutation period; these steps include some internal delays. The most important function is the watchdog time in which the motor EMF has to recover from a negative diode pulse back to a positive EMF voltage (or vice-versa) ...
