The utility model provides a kind of multi-unit moving coil motor, including at least two parallelly arranged substrates and the rotating shaft passing through the end surface of substrate, first coil winding and second coil winding are evenly arranged in the two end surfaces of substrate, first permanent magnet group and second permanent magnet group are arranged in the two end surfaces of substrate, first permanent magnet group and second permanent magnet group are all suspended outside first coil winding and second coil winding, fixed plate is arranged in the side of first permanent magnet group and second permanent magnet group away from substrate, first permanent magnet group and second permanent magnet group are all fixed on the fixed plate.The permanent magnet group of the application can form coverage to the deflection range of first coil winding and second coil winding, secondly, the magnet is arranged on both sides of coil in the application, compared with the magnet on one side, it has better magnetic field intensity.Finally, the application is arranged by parallelly arranging multiple substrates, compared with single substrate, it can provide stronger torsion to rotating shaft.
