特徴とする回動防止装置付きりニアモータ。A linear yoke comprising a cylindrical yoke to which a winding is attached, a cylindrical magnetic body concentrically installed outside the cylindrical yoke, and a rod-like yoke penetrating through the inside of the cylindrical yoke. In the motor, the magnetic body is magnetized in the radial direction, a non-uniform gap is formed between the inner circumferential surface of the cylindrical yoke and the outer circumferential surface of the rod-like yoke, and the magnetic material is magnetized in the radial direction. With a rotation prevention device, characterized in that a notch is provided so that the attraction force of the magnetic body is made different depending on the part of the rod-shaped yoke, thereby preventing rotation of the rod-shaped yoke. Near motor.
