Abstract

PURPOSE:To decrease the number of parts, and to simplify assembly work by unifying a stator clamper, a support shaft, a support plate and a baffle plate and constituting a stator supporter. CONSTITUTION:A support plate 7, a baffle plate 8 and a support ring 6 are unified, these parts are mounted to a stator clamper 4 while a stator core 3 is supported by a stator supporter 13 assembling these parts, a stator coil 5 is inserted into a slot for the stator core 3 from the inside diameter side. Accordingly, the stator clamper 4, the support ring 6, the support plate 7 and the baffle plate 8 are united and the stator supporter 13 is organized, thus eliminating the need for separate mounting of each part, then simplifying assembly work.

is a stator clamper that holds up this stator core (3) from both sides in the axial direction, and (5) is a stator clamper that is inserted into the slot of the stator core (31) and has both ends protruding from the end surface of the stator core (3). Stator coil, +61 is this stator coil (5)
(7) is a support plate whose one end is supported by the frame i11 and the stator clamper (4) and forms a cooling ventilation path together with the inner circumference of the frame; (8) is the support plate other than this support ring; 4 wind plates attached to the ends, (9th) rotor core inserted into the inner circumference of the above solid iron core (3) through a certain gap Wk, αQ is inserted into the slot of this rotor core (9). The inserted rotor conductor, αυ, is an internal fan provided with a predetermined gap t from the baffle plate (8), and (6) is a rotating shaft supporting this internal fan QIIY, which has the rotor core on its outer periphery. 19) is inserted.

Next, the operation will be explained. When the rotating shaft (6) rotates, wind pressure and air void are generated in the internal fan ■, causing the stator coil 15

Cooling. These cooling air are passed through the cooling core air passage to cool the rotary cage. [Problems to be solved] Conventional cooling
The stator of x* and its construction method are as described above in II.
rlt, it is necessary to use separate parts such as the support plate (7) and 4 air plates (8) to form the cooling ventilation path, and the support plate 16) of the 1 Amago coil also needs to be used separately. With praise,
Another problem was that these parts were disposed of in pieces and were not used in production.

This invention was developed to solve the above-mentioned problems, and provides a stator for rotating electric machines that can integrate each component and reduce the number of components, and a method for manufacturing the same. To get? purpose.

[Means for solving problems]

The stator of the rotary IL machine according to the present invention and its manufacturing method are such that the support plate, four air plates, and the support ring are integrated, and attached to the rigid clamper, and the assembled stator The support device is designed to support the stator core, and its removal is 1i! The coil is inserted into the slot of the stator core from the tP3 diameter.

[For production]

The rotary stator and the manufacturing method thereof according to the present invention include a stator support device that supports a stator core, stator coils, etc., and also constitutes cooling ventilation passages and baffle plates, and has a number of holes. is reduced.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to FIG. In FIG. 1, θJ supports the protruding maximum outer circumference of the stator coil (5) and II! i1 constant iron core (
3) is sandwiched in the axial direction, a cooling ventilation passage is formed by the inner periphery of the frame +11 and the support plate (7), and a stator support device also includes an air guide plate r for the cooling ventilation passage, Stator clamper (4), support (6), support plate (force, air guide plate (8)
It is composed of h.

What, are you explaining the other configurations to your colleagues?
Omitted.

Next, the operation 2 and manufacturing method 1 will be explained.

When assembling and manufacturing with a rotation speed of 1M&'ft, the stator core (3) is completely laminated on the frame. Next, the Enshiko support device [(1
3 Insert from the Y-axis direction and press down on the stator core (3) to secure it. Next, the slot for Kodakko Iron Core 13+? The stator coil +51"tm was fired from the inner diameter side, and after all the stator coils (5) for the number of slots were inserted, the protruding maximum outer periphery of the stator coil was supported and placed in a part (6). At that stage, the rotor (rotor/iron core (91, rotor coil IJG, 7 AN Uυ, rotating shaft (2), etc.) is inserted into the circumference of the iron core. Push it into t to complete the assembly of the rotating electric machine. do.

In this way, the stator clamper + 41% support (6), support plate (7), and air guide plate (8) were integrated into the stator support device i [Q3, so the public funds collected for each part were reduced. It disappears.

[Advantageous Effects] As described above, according to the present invention, the clamper, the supporting support, and the f: inserting plate d machining 4^ board are integrated to form ll811'
Since the JIi child support device is configured, each part can be attached with a 6-inch rope (and the unassembled work can be made into IIJI threads,
Also, it has the effect of oxidizing monoxide.
