The invention provides a moving-magnetic type linear motor which mainly comprises a stator and a rotor, wherein the stator comprises two yoke supporting rings in the shape of a circular ring, and at least four strip-shaped stator yokes which are uniformly distributed along the circular ring are arranged between the two yoke supporting rings; the inner surface of each stator yoke is in a tooth socket structure which comprises N stator teeth; a coil is coiled on the tooth socket structure; after the coil is electrified, adjacent stator teeth form opposite magnetic poles; the rotor is positionedin a cylindrical cavity surrounded by the stator yokes; for each stator yoke, the rotor has N-1 magnetic poles which are axially arranged in parallel, the magnetic lines of the magnetic poles are distributed in the radial direction, and the polarities of adjacent magnetic poles which are arranged at intervals are opposite; and the rotor is connected with a plate spring through a connection shaft.The moving-magnetic type linear motor reduces the magnetic leakage loss, improves the permanent magnet efficacy, has good radiating effect and simple and compact structure, and is convenient in installation and maintenance.
