The figure shows the schematic diagram of the commutation circuit. When the switch QS is in the "positive" position, the current iA of the auxiliary winding LA leads the current iA of the main winding LR, causing the motor rotor to rotate in the positive direction. If QS is turned to the "reverse" position, the direction of the current iA of LA changes by 180o, making the current iC of LR lead the current iA of LA, causing the rotor to rotate in the opposite direction.
