Abstract: A motor stator includes a stator core and a number of stator windings. The stator core includes a stator yoke and a plurality of stator tooth wrapped by a bobbin formed with an over-molding process, and further correspondingly wound around by stator windings. The stator teeth are connected to an inner surface of the stator yoke. A motor including the above motor stator and a rotor is also provided. The rotor includes a rotor core and a rotary shaft fixed relative to the rotor core. The rotor core is received in the bobbin and in magnetic coupling with the stator teeth.

Abstract: A brushless direct current motor, a stator part and its winding method are provided. The stator part includes a stator core and stator windings wound around stator poles. The stator poles and the stator windings are arranged in a one-to-one correspondence with each other. The stator windings are formed by winding a single conductive wire uninterruptedly on the stator poles. Two ends of the conductive wire are connected.

Abstract: A stator includes a housing made of magnetically conductive material, a plurality of magnets fixed to the stator housing; and a magnet holder attached to one end of the housing for fixing the magnets to the stator housing. The magnet holder includes a body and a plurality of locking structures extending from the body. Each magnet is locked between two adjacent locking structures. A plurality of cut-outs is formed in the stator housing, and a plurality of projections is formed on the body of the magnet holder and engaged with the cut-outs. Each locking structure includes a wedge-shaped inner end inwardly abutting against respective magnets to prevent the magnets from moving inwardly.
Abstract translation: 定子包括由导电材料制成的壳体，固定到定子壳体上的多个磁体; 以及附接到壳体的一端的磁体保持器，用于将磁体固定到定子壳体。 磁体保持器包括主体和从主体延伸的多个锁定结构。 每个磁体锁定在两个相邻的锁定结构之间。 多个切口形成在定子壳体中，并且多个突起形成在磁体保持器的主体上并与切口接合。 每个锁定结构包括向内抵靠各个磁体的楔形内端，以防止磁体向内移动。
