The invention provides an energy-saving and consumption-reducing vector control method and system for a double-stator excitation motor and the motor, and the method comprises the steps: constructing a relation model between the output torque Tm (t) of the motor and the real-time moving speed v (t) of an electric vehicle, calculating to obtain the expected real-time output torque Tem (t) of the motor, and selecting the power-on conditions of an inner stator winding and an outer stator winding; acquiring and converting to obtain an inner stator input current and an outer stator input current under a rotor magnetic flux dq coordinate system; calculating the real-time total torque TeBm = Bm, min output by the rotor under the condition that the total air gap magnetic flux density is minimized; optimizing by adopting a self-adaptive genetic neural algorithm to obtain an optimal real-time total torque meeting the requirement that the error with the expected real-time output torque is less than 8%, and further limiting the output optimal real-time total torque to enable the work efficiency of the motor to be greater than 75%. Different working modes of the inner stator and the outer stator can be selected according to the rotating speed and output torque requirements of the electric vehicle in different running states, and the motor has good adaptability to various working scenes.
