The invention discloses a permanent magnet synchronous motor driving mechanism for a tire crane and the tire crane. The permanent magnet synchronous motor driving mechanism comprises a hub reduction gear which is connected with a tire inner hub of the tire crane; a permanent magnet synchronous motor, which is connected with the hub reduction gear so as to drive the hub reduction gear; a brake, which is used for providing braking torque for the permanent magnet synchronous motor; a servo driver, which is used for controlling the permanent magnet synchronous motor; and a rotary transformer, which is used for providing rotation speed feedback of the permanent magnet synchronous motor for the servo driver to form rotation speed closed-loop control; the hub reduction gear comprises a first planet gear and a second planet gear connected with the first planet gear through a transmission shaft, the first planet gear is connected with the permanent magnet synchronous motor, and the second planet gear is connected with a tire inner hub of the tire crane. The positioning requirement of an automatic tire crane is met.
