T (CAP-TI) HE TIMING CAPACITOR Capacitor CAP-TI 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) ...

    ... Philips Semiconductors Brushless DC motor drive circuit If the chosen value of CAP-TI is too small oscillations can occur in certain positions of a blocked rotor. If the chosen value is too large, then it is possible that the motor may run in the reverse direction (synchronously with little torque). Fig.11 Typical CAP-TI and V ...

    ... Philips Semiconductors Brushless DC motor drive circuit The special PG pulse is derived from the negative-going zero-crossing from the MOT3 output. The external PG signal (PG IN) must sense a positive-going voltage ( 80 mV) within 1.5 to 7.5 commutation periods before the negative-going zero-crossing in MOT3 (see Fig.12). The voltage requirements of the PG IN input are such that an inexpensive pick-up coil can be used as a sensor (see Fig ...
