Excitation windings of such a motor is also formed by a parallel winding Ll and series winding, and it is shown in ( a ). In order to change the steering of the motor by changing excitation current, the direction of the current of L1 and L2 must be simultaneously changed, but such a change method is relatively trouble. The commonly used method is to change the direction of the armature winding current.
