The invention discloses a permanent magnet translational-motion type meshed motor. According to the permanent magnet translational-motion type meshed motor, a permanent magnet is used as a translational-motion rotor, two windings penetrate between two rotor magnetic poles, the two windings are wound on a motor shell in the mutually-perpendicular directions, four eccentric shafts are adopted to constraint rotation motion of the rotor, the energizing time and the direction of a current are appropriately controlled so that the rotor is driven to conduct the revolution motion in a radial plane, an inner gear ring which is fixedly connected with the rotor and a dead axel outer gear are driven to be meshed with each other, and the outer gear outputs the rotation motion. According to the permanent magnet translational-motion type meshed motor, a stator of the motor is a coil which is vertically wound on the motor shell in a staggered mode, and no stator core is arranged, so that eddy current loss is reduced. The rotor is the permanent magnet, so that the power density of the motor is improved.
