[Prior art] The armature of a conventional DC motor will be placed in a winding groove narrowed in the V-shaped V-shaped section with a V-shaped cross section, and the V-shaped section will be expanded. After the wide winding, the coil is fixed with a ring-shaped iron core to prevent the coil from falling off due to centrifugal force. (Refer to Japanese Patent "Kaihei n_2432652") (Problems to be solved by the invention) The conventional-general DC motor armature whose winding in the narrow opening of the V-shaped opening is affected by the winding in the winding groove. Limitation of the line accommodation rate makes it difficult to increase the efficiency of the motor. If the V-shaped opening is widened to increase the winding containment rate, it is necessary to make money for the winding. To prevent the winding from being separated by centrifugal force, it must be covered with a ring-shaped iron core. There is reluctance between the ring cores and it is difficult to increase the efficiency of the motor. It is necessary to perform insulation treatment on the armature iron core, and then arrange the windings directly in the winding grooves. Therefore, the winding workability is poor. The present invention is made to solve the above-mentioned problems. It makes the winding work and the assembling work of the armature coil excellent, and in order to increase the electric coil in the winding groove ^ winding density, ^ ^ to prevent winding The wire is detached and the magnetic gap of the armature part is eliminated to obtain a high-efficiency DC motor as its purpose. In addition, the second object of the present invention is to achieve a reduction in swirl resistance when the armature of the present invention is used in an in-tank fuel pump, etc. ~ ~ 314781 6 [Summary of the Problem] (Solution to Problem The armature structure of the DC motor of the present invention is attached to the armature iron core and is formed on the side of the salient pole of the winding groove between the salient poles of the salient pole facing the moment formed by the rotating shaft in a radial shape. A groove portion provided in parallel with the rotation axis; an armature coil which occupies half of the space of the winding groove is wound in a winding frame with a center hole and a flange through which the salient pole can be inserted; The two surfaces of the flat portion are brought into contact with the sides of the salient poles facing the winding groove and the inner surface of the center hole of the winding frame, and the two flanges of the winding frame are hung by the bent portions at both ends. 'And the planar part of the hooking magnetic sheet is provided with a protrusion protruding from the salient pole side (the two hooking magnetic sheets are opposed to each other to hold the winding king from the inside, and the armature coil containing the winding frame is inserted into the salient pole And let the protruding part hang on the groove part.

Moreover, Fig. 1 is a relationship diagram of an armature core and an armature coil of the present invention. SI is a DC motor of the present invention. Partial cross-sectional view of the armature. Figure 4 is a perspective view of the hanging magnetic sheet. In the figure, the electrical core 1 of the fJing Zhaocan 9 & The pivot system 1 is provided with salient poles la in a radial shape, and the convex surfaces of the salient poles have no protrusions. 'The front end is formed as a part of an arc. A lamination groove is formed between the V-shaped winding grooves (S〇lt). lb, and a groove portion parallel to the rotation axis 2 is provided on the surface of the salient pole formation and Ί 1 b. The coil 3 is connected to the winding frame 4 made of insulating material. Said lb half and two are evenly wound in an oblique shape. The flanges 4a and 4b of the winding frame 4 correspond to the oblique winding, so that the sizes of the two sides are different, and the core of the winding frame 4 is hollow. In order to facilitate the insertion of salient poles la. "Where the winding operation of the wire frame 4 is performed separately from the armature core 1; The wire ... is placed on the fixture 4c adjacent to the flange 4a without interfering with the flange and the armature coil 3.

This extended magnetism ... is formed into a circular arc shape of the extended salient pole i a with the protrusion 5c hanging = two hooks. The 'C side surface is formed in a shape along the inner surface of the extended magnetic pole 5a. The claw portion 5b for hooking the magnetic sheet 5 is composed of claws having two functions. 314781 8 1222260 holds the flange 4a by one of the claws to fix the bobbin 4 to the hooking magnetic sheet 5. The other claw portion is bent into a slightly opened shape, so that the force of pressing the armature coil 3 into the bottom of the winding groove lb can be elastically deformed, and the protrusion 5c is pressed against the side of the groove portion ic by the rebound force. After the armature coil 3 is assembled, the salient poles 1 a are firmly fixed to the salient poles 1 a. After the armature coil 3 is assembled, the winding end of the armature coil 3 is connected to the connecting piece 6 a of the commutator 6. At this time, as shown in FIG. 5, the enlarged portion is folded and an enlarged magnetic circuit 5d is formed to smooth the magnetic flux distribution at the front end of the salient pole ia. At this time, a thinned portion may be formed on the outer surface of the flange 4b to facilitate the storage and expansion of the magnetic circuit. The DC motor armature configured as described above is inserted into the salient pole la of the armature iron anger 1 together with the winding frame 4 and the hanging magnetic piece 5 of the armature coil 3 and the armature iron anger i respectively. The protrusion 5c is hooked on the groove part, and the armature coil 3 is fixed to the salient pole 1a by the magnetic sheet 5. Therefore, the winding work and the assembly workability of the armature coil 3 are good. At the same time, the winding density of the armature coil in the wire groove lb is increased, and the number of windings is increased. Therefore, the magnetic circuit of the armature core i has no connection gap, and a south-efficiency motor is obtained. Embodiment 2 Since the armature surface of Embodiment 1 is large, it is particularly suitable for a large rotation in a liquid, which hinders pump efficiency. To this end, a shaped plastic film needs to be formed. There are many irregularities, so when the wind resistance loss is lower than that of the armature fuel pump, the vortex resistance armature coil is made of resin to form a cylinder. The invention of the second embodiment is the armature of the first embodiment. 314781 9 The extended magnetic pole 5a of the sheet 5 can be easily flattened to reduce the vortex resistance.
