摘要： An electro magnetic device comprises a pair of relatively movable magnetizable members which have surfaces disposed in face to face relationship. One of the members is provided with spaced projections which locate in spaced slots formed in the other member, the projections having a smaller width than the slots so as to permit limited relative movement between the members. Some or all of the slots accommodate an electrical winding, the connection of the winding or windings being such that any two slots in which the flow of current in the windings therein is in the same direction are separated by a slot with either no winding or with a winding in which the flow of current is in the opposite direction. When the winding or windings are energized and when the projections are not centrally disposed in the slots, the members will be urged relative to each other to reduce the size of the smaller gap between each projection and the side face of the associated slot.

摘要： An electro-magnetic actuator includes a pair of magnetizable members, the one member being hollow and surrounding the other member. The other member defines a plurality of axially spaced circumferentially extending first ribs which are of reducing diameter towards one end of the member. The one member is generally of tapering construction and defines second ribs complementary to the first ribs. Recesses are defined between adjacent pairs of first ribs and accommodate windings. When electric current is applied to the windings the members move axially relative to each other to reduce the reluctance of the magnetic paths defined by the two members.

摘要： An electro-magnetic device comprises a first annular member and a second member having a cylindrical surface, the two members being interengaged. The presented surfaces of the two members are each provided with a two start or a multiple of a two start, thread formation thereby defining helical ribs on the two members. A winding is wound on the second member the winding arrangement being such that in the grooves or adjacent grooves the direction of current flow will be in the opposite direction when the winding is energized whereby the two members will move relative to each other to align the ribs on the members.
