A notched type one-way clutch (11) has a strut (8) which is accommodated, together with a spring (9), within a pocket portion (7) formed in a resinous stator body (1) and also has a notched plate (6), the notched plate (6) being combined with the stator body (1) in a relatively rotatable manner and provided with an engaging recess (10) with which the strut (8) comes into engagement in one rotational direction. A swing angle limiting portion (12) for limiting a swing motion of the strut (8) up to...

A stator has a pocket portion (8) of a notch type resin-made stator, in which strength of an outer corner R (12b) provided in the pocket portion (8) is increased to thereby prevent the resin-made stator body (1) from being broken from the outer corner R (12b). A stator has a pocket portion (8) encasing a strut 9 of a notch type one-way clutch (5). The pocket portion (8) is provided in a stator body (1) made of resin, and corner Rs (12a, 12b) are provided on both inner and outer sides of a strut ...

A stator which includes an insulating bobbin which is fitted upon a tooth. The insulating bobbin includes a tooth insulating portion which insulates between the tooth and a rectangular wire, and a first extending portion and a second extending portion which extend from the end portions of the tooth insulating portion roughly parallel with an inner surface of a yoke; a guide groove, which guides the rectangular wire from the outside of the first extending portion slantingly with respect to the ci...

A stator according to the invention has an elastoplastic element, which is disposed between the winding and the pole cog and which secures the winding firmly to the pole cog, thus preventing vibrations.

A stator according to the prior art is formed out of a laminated stack that is insulated by means of a plastic coating, and stator pole teeth are connected to each other in permeable fashion. A stator (20) according to the invention comprises separate permeable stacks of individual laminations (16) that are held together by means of a plastic coating. The return ring (30) is joined with play on the stack of individual laminations (18, 16, 1) and installed on the stack via bayonet coupling.

In a stator in which a damper mechanism is provided between a ratchet one-way clutch mechanism and a vane wheel, the damper mechanism is provided with a friction element.

A stator and a stator manufacturing method is provided in which a space factor can be improved, while reducing the number of components and simplifying the manufacturing process. A stator comprises a plurality of teeth cores 11 positioned at predetermined intervals on a predetermined circumference, a core back core 12 provided on a circumferential outside between adjacent teeth cores, and stator windings 13 which are wound around the teeth cores. An approximately U-shaped insulating sheet 14 is ...

The stator includes core back iron cores disposed on outer circumferential sides between a plurality of teeth iron cores disposed at regular intervals of a predetermined distance in a predetermined circumferential direction. A stator winding is disposed on inner circumferential sides between the plurality of teeth iron cores. The stator winding is constituted by a plurality of wire bundles each of which is a bundle of a predetermined number of electric wires and which are connected in parallel w...

In the segmented stator assembly disclosed, four teeth extend inwardly, and rectangularly relative to each other, from surrounding segments. The teeth form a bore at the center of the assembled segments. Each tooth has two parallel edges one of which extends along a line passing through the center of the bore. The centerline of each tooth is offset from the bore center. Coil-carrying bobbins are mounted on respective teeth so their axes coincide with the centerlines of the teeth on which they ar...

A stator for a motor in which there are provided a ring-shaped yoke portion iron core (2), tooth portion iron cores (3) arranged at an equal interval on the inner circumferential side of the yoke portion iron core (2), stator coils (5) fitted into slots (4) formed between respective adjacent tooth portion iron cores (3), and bridging portions (31) connecting the inner circumferential sides of the respective adjacent tooth portion iron cores (3), and a rotor (6) is oppositely disposed through a g...
