Claims

[Scope of utility model registration request]

A cylindrical magnet whose outer peripheral surface is magnetized with the same polarity, a yoke having an elongated notch arranged so as to surround the cylindrical magnet and provided parallel to the axis of the magnet, and a combination of the magnet and the yoke. a coil wound around a bobbin arranged movably in the direction along the axis of the magnet between the coils, a connecting piece extending outward from the flange of the bobbin through a notch in the yoke, and an outer side of the yoke. and a guide rod arranged parallel to the notch to support the connecting piece and guide the coil to move in a predetermined direction, and by energizing the coil, the coil is moved along the magnet. A linear motor made like this.
