The invention belongs to the field of electric vehicle power supply, and particularly discloses a wireless charger ground positioning system driven by a wire magnetic field. The system comprises a base, a stator assembly and a rotor assembly, and is characterized in that the base slides on a bottom plate through the matching of the stator assembly and the rotor assembly; limiting mechanisms used for being fixed to the bottom plate are symmetrically arranged on the two sides of the base, and alignment sensors are installed at the two ends of the wireless transmitting plate. Alignment adjustmentcan be performed on the whole device according to the offset position of the receiving plate so that the maximum effective charging receiving area can be guaranteed and the charging efficiency can beenhanced; the stator assembly and the rotor assembly are matched to form a driving structure according to the principle that an electrified conductor generates force in a magnetic field, bidirectional driving adjustment is achieved by changing the direction of coil current in the stator assembly, the charging device can be used as a power source for overall transverse movement of the charging device, the structure is simple, controllability is high, and the internal structure of the charging device is greatly simplified. Space is saved, noise is low, and stability is high.
