The invention provides a crane wheel with a built-in permanent magnet synchronous motor, and relates to the technical field of cranes. The crane wheel is characterized by comprising a wheel carrier, ahollow hub, web plates and an outer rotor permanent magnet synchronous motor, wherein the two ends of a stator shaft of the outer rotor permanent magnet synchronous motor are correspondingly fastenedand connected with the two sides of the wheel carrier correspondingly; the outer edge of an outer rotor of the outer rotor permanent magnet synchronous motor is sleeved with the hollow hub, and the outer rotor is in corresponding transmission connection with the hollow hub; an annular groove corresponding to a track is formed in the edge surface of the hollow hub; the two sides, corresponding tothe outer rotor, of the stator shaft are movably sleeved with the web plates through bearings; the two web plates are correspondingly fastened and connected with the end surfaces of the two ends of the hollow hub correspondingly; and a wheel edge rail clamping device used for braking the hollow hub is arranged at the upper part in the wheel carrier. According to the crane wheel, the problem that an existing crane wheel is large in size is effectively solved.
