摘要： In order to reduce load supported by a support mechanism for supporting a movable part so as to prevent the movable part from moving in a horizontal direction when stress is generated thereon in the horizontal direction, there is provided a drive unit including a primary side having a magnetic body around which a coil is wound, and a secondary side having a plurality of permanent magnets, the primary side including magnetic poles and step portions provided on the magnetic poles. The width of each step portion is smaller than the width of each permanent magnet.

摘要： The conventional linear drive apparatus has the problem that in constructing a linear motor of a multiphase structure by connecting a plurality of armature units, the length of the armature becomes longer in proportion to the number of the phases, thus limiting the locations where the apparatus can be installed. The problem is solved by a linear drive apparatus comprising a plurality of armature units 3 formed by a magnetic material on which a conductor coil 4 is disposed, and an armature comprising an arrangement of the armature units 3. The armature units 3 comprise a plurality of opposing portions having opposing magnetic pole teeth. The magnetic pole teeth of adjacent opposing portions are arranged in an interdigitated manner. A secondary member 6 is disposed between magnetic pole teeth of the opposing portions. The armature units 3 comprise the coil 4 arranged on opposite sides thereof in an alternating manner.

摘要： A linear motor for generating a linear motion in a linear direction, has a plurality of first members, each of which includes an electromagnetic coil for generating a first magnetic field, and a magnetic core (magnetically permeable) having magnetic surfaces being opposite to each other so that the first magnetic field passes a space between the magnetic surfaces, and a second member arranged in the spaces to be relatively movable linearly with respect to a combination of the first members to generate the linear motion in the linear direction, and including a magnet polarized in a polarizing direction to generate a second magnetic field.
