    摘要： The linear actuator includes an inner core (2), and an outer core (3) provided outside the inner core in a radial direction while being supported by a pair of flat springs (41 and 42). Permanent magnets (23 and 24) are formed at one of the inner core and the outer core, and magnetic pole portions (31a and 32a) are formed at the other of the inner core and the outer core to face the permanent magnet with predetermined gaps formed therebetween. Spacers (71 and 72) are respectively provided between the inner core and the flat springs, abutting portions are respectively configured by abutting facing surfaces of the spacers and the inner core and facing surfaces of the spacers and the flat springs adjacent to the spacers in the axial direction, and at least an engagement portion including a recess and a protrusion are arranged at the abutting portions.

    摘要： A linear actuator comprising a first assembly, a second assembly, and a magnetic sensor. The second assembly is linearly movable with respect to the first assembly such that the linear actuator is configured so as to be in one of a plurality of linear positions. The first assembly and the second assembly cooperatively define a magnetic pathway. The magnetic pathway is configured to vary in length with linear movement of the first assembly with respect to the second assembly. The magnetic sensor is configured to output a signal indicative of the magnetic field flux routed via the magnetic pathway.

    摘要： This linear motor apparatus includes: a first linear motor and a second linear motor, movable bodies of which move in the same direction in a linked manner; a first control portion that causes the first linear motor to produce thrust to apply a load to a pressurizing target via the movable bodies; and a second control portion that causes the second linear motor to produce thrust and controls the thrust, wherein, if the first control portion is causing a load to be applied to the pressurizing target, then the second control portion causes the second linear motor to produce thrust that cancels an external force produced to the movable bodies.

    摘要： An inner diameter of a third stator core is greater than an inner diameter of a second stator core. When a first stator core, the second stator core, and the third stator core are placed in an inner periphery of a coil, a jig is inserted from an inner-periphery opening of a first end side of the third stator core into the third stator core to directly position the first stator core, the second stator core, and the third stator core in a radial direction. Therefore, a side force generated by an axis deviation between the first stator core, the second stator core, and the third stator core can be reduced.
