The invention discloses a permanent-magnet linear motor with a compensation module. The permanent-magnet linear motor comprises a stator, a rotor, a connection block and the compensation module, wherein the connection block is arranged at one end of the stator and is embedded between the stator and the compensation module, the compensation module comprises an auxiliary permanent magnet, a compensation winding and two compensation iron cores, each compensation iron core is in a right-angle shape, the auxiliary permanent magnet is arranged between the two compensation iron cores and forms a compensation groove with the two compensation iron cores, and the compensation winding passes through the compensation groove and is wound around connection parts of the two compensation iron cores and the auxiliary permanent magnet. Through the permanent-magnet linear motor with the compensation module, disclosed by the invention, the force fluctuation can be effectively reduced, so that the positioning accuracy and the reliability of the permanent-magnet linear motor are improved, and the service lifetime of the permanent-magnet linear motor is prolonged.
