The utility model discloses a reciprocal push -and -pull electromagnetism directly drives device, including shell, drive unit, active cell, load bar and connecting rod, drive unit and active cell setup in housing cavity internally, and load bar sets up on a side end face of active cell direction of motion, and the connecting rod sets up on the opposite side terminal surface of active cell direction of motion, load bar and connecting rod all run through the shell that corresponds the side and with shell sliding connection, drive unit includes stator core and sets up the winding on stator core,all be equipped with a plurality of tooth's socket on the coupling surface of stator core and active cell, be equipped with the air gap between active cell and the drive unit. The beneficial effectsof the utility model are that: under different in chronological order's drive current's effect, drive unit produces the magnetic resistance thrust on not equidirectional to the active cell, can be reciprocating motion by the direct drive active cell, does not need intermediate gearing, simple structure, and the maintenance volume is little, safe and reliable, pollution -free, the life cycle is long.
