Figure 7. Electrical schematic

The real implemented system is shown in the schematic below. ST52x301, the integrated full-bridge dual

drive and three AND’s are enough to control the BLDC motor.

The basic idea used in this implementation employs the Hall sensors in a direct way. The Hall signals

are "AND-ed" directly with a PWM wave produced by ST52x301 in order to supply the proper winding. In
