Consider the drive circuit for a three phase brushless DC motor shown in Figure 8.32. ... Let us focus on the ON/OFF state of six power transistors (Tr1 , ..., Tr6) in order to generate torque in the forward and reverse direction. ... Hint: make a table with columns being the transistors 1 through 6 states, the position of the rotor at the beginning of each transistor state switching sequence, and the magnetic fieldanbsp;...
