Abstract: An electromagnetic structure comprising permanent magnets comprises an outer yoke (a6), a first permanent magnet group (a3, a5), an inner yoke (a8), an armature (a1), and a second permanent magnet group (a2, a4). The outer yoke is in a hollow cylinder shape. The first permanent magnet group comprises multiple permanent magnets arrayed in a round shape, the multiple permanent magnets are connected to the outer yoke, and a magnetizing direction of each permanent magnet is along an axial direction. The inner yoke comprises an inner yoke upper base, an inner yoke sidewall, and an inner yoke lower base. The inner yoke upper base and the inner yoke lower base are separately extended outwards and horizontally from an upper end and a lower end of the inner yoke sidewall to form a circular ring. The armature comprises an armature upper base, an armature lower base, and an armature barrel body. The armature barrel body penetrates through the inner yoke sidewall, and the height of the armature barrel body is greater than that of the inner yoke. The armature upper base and the armature lower base are separately in a round shape with a diameter greater than an inner diameter of the inner yoke sidewall. The second permanent magnet group comprises multiple permanent magnets arrayed in a round shape, the multiple permanent magnets are connected to the outer yoke and the inner yoke, and a magnetizing direction of each permanent magnet is along an axial direction. The electromagnetic structure is low in power consumption of a coil, has a good shock resistance performance, and has a good capability against the centrifugal acceleration impact.
