Abstract
Improved electromagnetic device comprising a pair of relatively movable magnetizable members and one or more windings through which an electric current can be passed to produce a magnetic field intended to effect relative movement of the members, in which one of said members defines a series of grooves arranged in collateral relation on one face of such a member, the other member defining a series of projections that penetrate the respective grooves and that are less width than these, some or all of these grooves accommodating an electric winding, the connection of the winding or windings being such that any two grooves, in which the current flow in the windings contained in them occurs in the same direction, are separated by a groove without winding or with one in which the flow of current takes place in the opposite direction, the arrangement being such that, if the members are positioned so that the p sprays are not centrally arranged in the grooves, such members will be propelled towards each other to try to reduce the size of the smaller gap between each projection and the lateral faces of the associated groove.
