Abstract: A single-phase brushless motor includes a stator and a rotor rotatable with respect to the stator. The rotor includes a number of permanent magnetic poles. The stator includes a stator core and a winding wound on the stator core. The stator core includes an outer annular portion, an inner annular portion, and connecting portions connecting the inner and outer annular portions. The winding is wound around the connecting portions. The rotor is received in the inner annular portion. The inner annular portion and the rotor form a substantially uniform air gap. A recess is formed in an inner surface of a part of the inner annular portion between each pair of adjacent connecting portions. A center of each recess deviates from a center line of symmetry of the corresponding pair of connecting portions.

Abstract: A relay has a driving device that includes a magnet portion, two electromagnets, a yoke portion fixed to the above elements, and a rocking armature. The magnet portion includes a ferrite permanent magnet polarized in a direction perpendicular to the yoke portion and a bearing surface facing way from the yoke portion. Each electromagnet includes an iron core fixed to the yoke portion and a coil wound thereon. The two iron cores are arranged at opposite sides of the magnet portion. The rocking armature includes two arms connected to each other with an included angle formed therebetween and a convex joint of the two arms. The convex joint abuts against the bearing surface and the rocking armature pivots about the convex joint between a first position and a second position in which the rocking armature contacts a respective one of the iron cores.

Abstract: A stator core includes at least one bendable strip-shaped core. Each strip-shaped core is formed by stacking a plurality of laminations. Each lamination includes at least two yoke portions and at least two tooth portions. Every two adjacent yoke portions are connected to each other via a bendable portion and have two opposite end surfaces, one of the end surfaces having a groove and the other having a projecting rib. After the bendable portion is bent the projecting rib is engaged in the groove to form an interlock structure such that relative circumferential movement between the adjacent yoke portions is limited.

Abstract translation: 定子芯包括至少一个可弯曲的带状芯。 每个条形芯通过堆叠多个叠片形成。 每个叠片包括至少两个磁轭部分和至少两个齿部分。 每两个相邻的轭部分经由可弯曲部分相互连接并具有两个相对的端面，其中一个端面具有一个凹槽，另一个具有突出肋。 在可弯曲部分弯曲之后，突出肋接合在凹槽中以形成互锁结构，使得相邻磁轭部分之间的相对周向运动受到限制。
