The utility model discloses a device is directly driven in the reciprocal push -and -pull of magneto, including active cell, isolation layer, winding, side magnetic conduction board and two " E " shape stator. A motor that uses the reciprocal push -and -pull of this magneto directly to drive the device is still disclosed. The beneficial effects of the utility model are that: having small, simple structure, clean safe advantage, not needing drive mechanism, adopt electric exciting mode to realize the direct drive, the flow direction through the control winding intermediate -current realizes thecontrol to the direction of motion, size through the control winding intermediate -current realizes the control to the output torque size, the condition such as no mechanical wear, deformation, deterioration of oil, oil leak, maintenance cost is little, safe and reliable.
