Problems solved by technology
[0002] It is known that the steering control of the three-phase motor must switch and control the power phase of the three-phase motor, and the related control circuit or program must be changed accordingly to detect the steering of the motor and the position of the rotor correspondingly, resulting in a rather complicated control circuit or program. Also increase considerable design cost and component cost

The invention provides a steering control system for a three-phase motor. The steering control system comprises a group of three-phase motor coils, a group of three-phase induction circuits, a controlcircuit and a control switch group. The three-phase induction circuit is used for inducting the position of a rotor. The control circuit is used for providing a three-phase coil signal and receivinga three-phase induction signal, the three-phase coil signal is used for providing a signal to the three-phase motor coil, and the three-phase induction signal is from the three-phase induction circuit. The control switch group is used for simultaneously switching and controlling the three-phase coil signal to the three-phase motor coil and the three-phase induction signal from the three-phase induction circuit so as to control the steering of the three-phase motor. Therefore, the three-phase coil signal and the three-phase induction signal are simultaneously switched and controlled by using the control switch group so as to correctly sense the position of the rotor, and the control circuit does not need to carry out any circuit change design or program modification, so that the design andelement cost can be saved, and the complexity of element maintenance is reduced.
