The present invention is provided to enable a second member including a permanent magnet to reciprocate in a first member in which armature modules winding coils are arranged in each magnetic pole to be perpendicular to a core which is a magnetic material. The present invention is provided to mount the second member on a plurality of mounting surfaces and to reciprocate the second member with strong driving force from each first member to a moving magnetic field. The present invention is provided to reciprocate the second member in the first member through a hole and to enable a cooling module, which restricts the heat of the first member and the second member, to efficiently improve a heating problem of a device which rapidly operates according to various embodiments. |
