うに軸の回転力を得ることができない。BACKGROUND ART Conventionally, various induction motors and various DC motors have a stator and a rotor as a pair, and motors whose shafts are usually rotated only by electromagnetic force are used. A special example is a linear motor in which the stator is arranged in a plane.This has the function of moving the movable part corresponding to the rotor parallel to the stator surface, but unlike a general electric motor, it has the function of moving the movable part corresponding to the rotor parallel to the stator surface. cannot obtain rotational force.

いう問題がある。Therefore, in order to cause the shaft to perform reciprocating motion in the axial direction in addition to rotational force, the electric motor must be driven by a separate drive device or some kind of drive mechanism must be installed at the end of the motor shaft. The problem is that it cannot satisfy the two functions of kinetic force.

させる原理を図を用いて説明する。It is generally well known that when a motor passes current through the coils of its stator, the rotor rotates due to electromagnetic induction. The electric motor of this invention has the same principle as the conventional electric motor up to the point where rotational force is obtained. Therefore, the explanation up to obtaining the rotational force will be omitted, and the principle of reciprocating the rotor in the axial direction will be explained using the drawings.

手順は３のコイルに電流を流し、２の電流を切ると４は
３と相対する位置まで動き回転する。The principle of reciprocating motion in the axial direction is shown step by step. First, when a current is applied to the coil of the stator 2, the rotor 4 is attracted to the stator 2 by electromagnetic force, moves to a position facing the stator 2, and rotates at that position. Hereinafter, the names stator and rotor will be omitted and the operation will be explained using numbers.The next step is to apply current to coil 3, and when the current in 2 is cut off, 4 moves to a position opposite to 3 and rotates.

スピードで回転子軸の往復運動が可能になる。As explained above, by switching the stator coil current, it is possible to move the rotor 4 in the axial direction in the range from the stator 1 to the position opposite to the stator 3. By continuously controlling the switching of energization, it is possible to reciprocate the rotor shaft at any speed.

The reciprocating motion is also based on the concept of the present invention and is included in the present invention. Furthermore, by arranging three or more cylindrical stators and connecting two or more rotors with one shaft, it is possible to control the speed and stroke of the reciprocating motion of the shaft, but this is also the idea of the present invention. and is included in this invention.
