ABSTRACT:
The bistable electromagnet comprises a magnetic circuit partially surrounded by a winding constituted by a series of links (M1, M2, M3, M4, M5, M6) interconnected by air gaps, the links of a first type being movable relative to the other links of a second type, certain types of links comprising a permanent magnet (1, 3, 5, . . . ) provided on its pole surfaces with pole pieces (7, 8; 11, 12; 15, 16; . . . ) whose ends define two air gap zones with the neighboring links of the other type.
Each permanent magnet (1, 3, 5) of one type of link (M1, M3, M5) is subjected to the influence of a winding (21, 23, 25) whose field is perpendicular to the magnetic direction of said permanent magnet and directed toward one or the other of the ends of its pole pieces and the links of the first type (M2, M4, M6) comprise also a permanent magnet (2, 4, 6) provided with pole pieces, such that the electromagnet will have the form of a closed chain, which can follow a variable path within a plane and can give rise, along its length, to forces perpendicular to this plane.
Used particularly in bistable electromagnet clutches. (See FIG. 1).
