DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic drive device, and more particularly to a device that linearly reciprocates a permanent magnet according to the polarity number of a fixed electromagnet, thereby extracting a direct driving force.

Conventionally known electromagnetic and drive devices, that is, electric motors, are generally in the form of so-called motors and extract power in the form of rotational force. In addition to its complicated structure and the need for coil winding, it also has the major problem of not being easy to manufacture or repair. Since the operating principle of the motor is a hunting action caused by the rotating magnetic field between the rotor and the stator, when the load exceeds the input current value increases, which always results in coil burnout. Moreover, the coil windings are very complex, which requires time to maintain and repair, which is a major drawback.

The present invention has been made to solve the above problems, and its main purpose is to provide linear reciprocating motion to a permanent magnet inserted in the magnetic field by changing the polarity of a pair of electromagnets. The object of the present invention is to overcome the drawbacks of conventional motors by providing a magnetic drive or electric motor capable of generating .

According to this embodiment, depending on the input current! ll electromagnet 20゜4
A magnetic field is generated between the two poles, and the movable magnet 20 undergoes a reciprocating motion as in the first embodiment. Due to this reciprocating motion, the inner cavity of the cylinder 10 is divided into left and right sides by the movable fJrM1 stone 20. Since all the chambers in the chamber repeat the expansion and contraction of their volumes, suction force and compression force are generated in the chambers, so the above-mentioned outlet and inlet ports 33c and 33d
and 43C143d and their check valves 91, 92 and 91°92 also mutually control the direction, and together they perform a pumping action by electromagnetic drive.
