    摘要: There is provided a long-proportional-stroke force motor whose force vs. stroke characteristic provides a long stroke in which a constant force is output proportional to the exciting current in magnitude without involvement of problems in actual use, and which does not impose any limitations on the stroke so as to effectively use the stroke.A long-proportional-stroke force motor 1 includes a magnetic circuit configured such that a spacer 12 made of a non-magnetic material intervenes between a guide 11 made of a magnetic material and a sleeve 13 made of a magnetic material, and an armature 3 provided movably within the magnetic circuit. A side, located opposite to the armature 3, of a sectional profile of an end portion of the guide 11 adjacent to the spacer 12 assumes a curve which satisfies both expressions in the following Expression 7,  Y  X > 0 ,   2  Y  X 2 > 0 , [ Expression   7 ] where X is a coordinate of an axial direction of the guide; a positive direction of an X-axis is a direction in which the armature is attracted through the application of exiting current; and Y is a coordinate on the guide along a direction orthogonal to the X-axis.

    摘要: A core made of a soft magnetic material is supported to be movable, and a permanent magnet is mounted to move with the core. At least one electrically conductive drive coil is located adjacent the core and one pole of the permanent magnet. A casing, made of a soft magnetic material, is located adjacent to the drive. An electrically conductive sense coil is located adjacent one end of the core, such that when electrical current is passed through the drive coil in a first direction, the core is moved in a first direction and an electrical property associated with the sense coil is altered, thereby indicating the position of the core, and when electrical current is passed through the drive coil in a second direction, the core is moved in a second direction and an electrical property associated with the sense coil is altered, thereby indicating the position of the core.

In accordance with one aspect of the invention flat magnets and flux focussing elements are used to provide the radially directed flux. In accordance with another aspect the coil sections are wound onto a core element to provide an attached coil design. Finally, a brushless actuator design is disclosed.
