ない。 Conventionally, this type of flat motor has a structure as shown in FIG. That is, 1 is a flat motor, 2 is a flat case made of magnetic material, 3 is a flat armature, 4 is a bracket made of magnetic material, and armature 3 is fixed to rotating shaft 6 together with commutator 5, bearings 7, 7. It is supported by the case 2 and the bracket 4 via.
8 is a magnet attached to case 2, and 9 is a brush. 10 is Sirotskovian, 11,
11' is an end plate, and 12 is a blade, which are fixed to the rotating shaft 6. In a flat type motor with this type of structure, the motor part and the fan part are completely independent, and there are no common parts between the motor part and the fan part, so the number of parts is large, and the fan has no air flow. Therefore, there is no function to actively cool the motor.

る。 The present invention improves such a conventional flat type motor, and the present invention will be described below in a second embodiment showing the present invention.
The explanation will be given with reference to the drawings and FIG. 5. In Fig. 2, 1 is a flat motor, 2 is a flat magnetic case, 3 is a flat armature, 5 is a commutator, and the armature 3 and commutator 5 are fixed to a rotating shaft 6, bearings 7, It is supported by case 2 via 7. 8 is case 2
The magnet attached to 9 is a brush. 10 is a Shirotskov fan, 11 and 11' are end plates, and 12 is a blade. Thus, the end plate 11 is made of a magnetic material and is attached to the rotating shaft 6 in a state where it overlaps the armature 3. The end plate 11 covers the opening of the case 2 and rotates with a small gap relative to the case 2. As the Sirotskov fan 10 rotates, air is sucked in and blown as shown by arrow P.

示すように送風される。 The embodiment shown in FIG. 3 is very similar to the structure shown in FIG.
0' is used, and the other structure is the same as that shown in FIG. 2, so the same reference numerals are given to the corresponding parts. The armature 3 and the cross flow fan 10' are rotatably supported by the case 2 and outside the case 2 via bearings 7, 7'. According to the cross flow fan 10', air is blown as shown by arrow Q.

である。 Next, looking at the magnetic path of the magnetic flux generated by the magnet 8, in the motor of the present invention, as shown in Figure 5a, the magnetic flux M coming out of the N pole of the magnet 8 enters the armature 3 and is linked to the coil 3a. They cross each other, form a magnetic path, pass through the magnetic end plate 11 that acts as a yoke, and return to the S pole of the magnet 8. In this magnetic path, the only air gap is the gap δ1 between the magnet 8 and the armature 3.

It then enters the armature 3 again, interlinks with the coil 3a, and returns to the S pole of the magnet 8. During this time, there is a gap δ1 between the magnet 8 and the armature 3, and a gap δ2 between the armature 3 and the bracket 4.

のすぐれたものである。 As is clear from the above embodiments, the fan-equipped flat motor of the present invention includes a magnet mounted in a flat case, a flat armature facing the magnet with a slight gap in the axial direction of the armature, and
One end of the rotary shaft of this armature is rotatably supported in the case via a bearing, and at least one end plate of the fan, which is composed of blades such as a Sirotskov fan or a turbo fan, and an end plate for holding the blades, is magnetically attached. The end plate is attached to the rotating shaft of the armature in a state where it is overlapped with the armature, and the end plate is arranged with a gap between the end plate and the opening of the case. It is covered with a plate, and the end plate of the fan is also used as the motor bracket or yoke member, so the number of component parts of the flat motor with fan can be reduced, and the axial length can be reduced. Furthermore, since the armature is in contact with the fan's air path through the end plate of the fan, the air cooling effect is excellent.
