The invention discloses a wheeltrack traffic linear traction motor which comprises a primary part and a secondary part. The primary part comprises an iron core and three-phase windings symmetrically embedded in iron core grooves of the iron core; the three-phase windings comprise main windings and auxiliary windings. Three-phase coils of the auxiliary windings are respectively in parallel connection with capacitors and then respectively in parallel connection with three-phase coils of the main windings. The main windings are arranged at the upper portions in the iron core grooves, the auxiliary windings are arranged at the lower portions in the iron core grooves, and the auxiliary windings are arranged at the groove positions in front of the main windings. Compared with current of the main windings, the capacitance of the capacitors is set to be capable of enabling the current of the auxiliary windings to have a phase lead of a preset angle. In the wheeltrack traffic linear traction motor, when the main windings of the primary part are connected with a three-phase alternating current power supply, leading current is generated in the auxiliary windings to provide reactive current required by the wheeltrack traffic linear traction motor, absorption of the reactive current in a power grid is further reduced, and the aim of improving a power factor is achieved, so that output current of a traction system can be effectively reduced.
