Claims

[Scope of utility model registration request]

A plurality of drive coils are arranged in series on a long flat plate that also serves as a magnetic yoke, and the drive coils are arranged so as to move opposite to the drive coils, and are magnetized in the thickness direction so that the polarity is opposite. In a movable magnet type linear motor comprising at least two movable magnets connected in series, a part of a slider supporting the movable magnet is provided with a position detection magnet for detecting the position of the movable magnet, Furthermore, for each at least one of the plurality of drive coils,
A magnetically sensitive element arranged corresponding to the moving position of the position detection magnet, and a switching element connected in series to the corresponding drive coil and closed by the magnetically sensitive output of the corresponding magnetically sensitive element. a movable magnet type, characterized in that, when the position detecting magnet corresponds to the position of the magnetically sensitive element, a current flows through the switching element to a drive coil connected to the switching element. linear motor.
