  • Publication number: 20100300860
    Abstract: An armature winding switch module has a first connection set, a second connection set and a third connection set. The first, the second and the third connection set are respectively connected between a neutral point and a corresponding phase line point and have terminals and contacts. Each two terminals of each connection set are respectively connected to two ends of a corresponding armature winding of a power supply device. The contacts of each connection set are connected among the corresponding terminals. Selectively turning on/off the contacts can connect the armature windings of each connection set in series or in parallel and thereby output required voltage without redoing wiring work. Therefore the present invention avoids second time complicated wiring work and possible connection faults.
