The invention discloses an electromagnetic driving machine. The electromagnetic driving machine comprises a main hollow housing. By employing the electromagnetic principle technology and matching withthe rotation technology of a crankshaft, the longitudinal movement from the upper portion is converted to a transverse rotation state so as to achieve the drive effect, and the electromagnetic principle is employed to perform longitudinal movement through driving and the buffer processing is implemented at the collision position of the components so as to reduce the work noise while achieving therotation force transfer. The device comprises a permanent magnet field type longitudinal driving mechanism to generate the longitudinal driving action under the action of magnetic field strength. Besides, the device comprises a universal rotary type force conversion connecting mechanism capable of converting the longitudinal motion mode from the upper portion to the circular motion with a certainrotating capacity at the lower portion so as to achieve the rotating driving function of the crankshaft. The device comprises a motor-driven guide mechanism for a rotational direction to give the initial guide effect to the rotational direction of the crankshaft so as to control the direction of the rotational drive.
