... Philips Semiconductors Brushless DC motor drive circuit APPLICATION INFORMATION Introduction Figure 5 shows full–wave driving of a three phase motor requires three push–pull output stages. In each of the six possible states two outputs are active, one sourcing and one sinking current. The third output presents a high impedance to the motor which enables measurement of the motor EMF in the corresponding motor coil by the EMF comparator at each output ...
