Figure 1 shows the functional block diagram of using 8751 single chip to control the brushless DC motor.8751's P1 is connected with the 7406 inverter control to control the brushless DC motor commutation,P2 is used for measuring the signal H1, H2, H3 from position sensor,P0 externally connects a digital to analog converter.According to the commutation of stator windings, first it needs to find the state of three rotor magnet position sensor signals H1,H2,H3 and the relationship between 6 power tubes,then it puts the information in tabular form to the single-chip's EEPROM.
