Description

Technical Field

[0001] The utility model relates to the technical field of generator stators, and particularly relates to a novel generator stator. Background Art

[0002] The stator is a fixed part of a machine. The stator is composed of a stator core, a stator winding and a frame. The main function of the stator is to generate a rotating magnetic field, and it is the non-rotating part when a brushed or brushless motor is working.

[0003] At present, when the generator stator operates with the rotor for a long time, the temperature between the stator and the rotor will continue to rise. Usually, the means adopted is external or internal air cooling for temperature control. However, after the stator core is stacked, the winding and the stator core part are relatively sealed. As the temperature inside the chassis continues to rise, high-energy capacitive discharge-accelerated electrons will cause damage to the winding and the insulation part along with the high temperature.

[0004] Regarding the components of the stator, how to improve the current-carrying capacity of the stator core for the winding to improve the direct injection of the cooling air flow into the inside of the stator core and the winding is the technical difficulty to be solved. Content of the Utility Model

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by the utility model is as follows:

[0007] A novel generator stator includes a positioning component and a core component installed on the positioning component;

[0008] The positioning component includes a first protective gasket ring, a plurality of reinforcing struts welded inside the first protective gasket ring, and a second protective gasket ring welded on top of the plurality of reinforcing struts;

[0009] The core component includes a gasket ring movably installed outside the reinforcing strut and a clamp seat movably installed outside the gasket ring.

[0010] The utility model can be further configured in a preferred example as follows: clamping grooves are formed outside the gasket ring, guiding holes are formed inside the clamping grooves, a diversion groove is formed outside the gasket ring, and the diversion groove is located inside the adjacent two clamping grooves.

[0011] The utility model can be further configured in a preferred example as follows: cushion feet that are recessed inward are formed at the top and bottom of the clamp seat.

[0012] In a preferred embodiment, the present utility model can be further configured as follows: both the first protective gasket ring and the second protective gasket ring are made of thickened silicon steel sheets, and holes adapted to clamp the reinforcing struts are provided inside the first protective gasket ring and the second protective gasket ring.

[0013] In a preferred embodiment, the present utility model can be further configured as follows: the flow guiding groove is elliptical, and the flow guiding groove is in communication with the pad feet.

[0014] In a preferred embodiment, the present utility model can be further configured as follows: four symmetrically distributed pad feet are provided at one end of the clamp seat close to the inner side of the gasket ring, and the pad feet are adapted to penetrate through the clamp groove.

[0015] By adopting the above technical solutions, the beneficial effects obtained by the present utility model are as follows:

[0016] 1. By providing a flow guiding groove for guiding air flow between two adjacent clamp grooves, the pad feet can be in communication with the flow guiding groove. After the coil is wound around the outside of the clamp seat, multiple gasket rings and clamp seats positioned and constrained by a plurality of reinforcing struts can provide a bearing platform for the wound coil. As the rotor on the inner side of the gasket ring rotates at a high speed, the blown cooling air flow can directly enter the flow guiding groove and the pad feet, and finally the cooling air flow will blow the coil wound around the outside of the clamp seat. At this time, the novel stator assembly can provide temperature control protection for the winding and the insulating material on the winding. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer and more explicit, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model.

[0027] The following describes a novel generator stator provided by some embodiments of the present utility model with reference to the accompanying drawings. Embodiment 1

[0028] Combined Figures 1 - 5 As shown, a novel generator stator provided by the present utility model includes a positioning assembly 100 and a core assembly 200 mounted on the positioning assembly 100.

[0029] The positioning assembly 100 includes a first protective gasket ring 110, a reinforcing strut 120, and a second protective gasket ring 130. The core assembly 200 includes a gasket ring 210, a clamping groove 220, a guiding hole 230, a flow guiding groove 240, a clamping seat 250, and a gasket foot 260.

[0030] Specifically, a plurality of reinforcing struts 120 are welded inside the first protective gasket ring 110, the second protective gasket ring 130 is welded on the tops of the plurality of reinforcing struts 120, the gasket ring 210 is movably mounted outside the reinforcing struts 120, and the clamping seat 250 is movably mounted outside the gasket ring 210.

[0031] By using the uniformly distributed clamping grooves 220 opened outside the gasket ring 210, a guiding hole 230 is opened in the middle of the clamping groove 220, and a flow guiding groove 240 for guiding air flow is opened between two adjacent clamping grooves 220. At the same time, a clamping seat 250 is movably mounted outside two adjacent groups of clamping grooves 220, and symmetrically distributed gasket feet 260 are opened at the top and bottom of the clamping seat 250. At this time, the gasket feet 260 can be in communication with the flow guiding groove 240. After the coil is wound outside the clamping seat 250, multiple groups of gasket rings 210 and clamping seats 250 positioned and constrained by the plurality of reinforcing struts 120 can provide a bearing platform for the wound coil. As the rotor inside the gasket ring 210 rotates at a high speed, the blown cooling air flow can directly pour into the flow guiding groove 240 and the inside of the gasket feet 260. Finally, the cooling air flow will blow the coil wound outside the clamping seat 250. At this time, the novel stator assembly can provide temperature control protection for the winding and the insulating material on the winding, so as to avoid the problem that high-energy accelerated electrons may burn the winding and the insulating material. Embodiment 2

[0032] Combined Figure 2As shown, on the basis of Embodiment 1, both the first protective gasket ring 110 and the second protective gasket ring 130 are made of thickened silicon steel sheets, and holes adapted to clamp the reinforcing strut 120 are provided inside the first protective gasket ring 110 and the second protective gasket ring 130.

[0033] By respectively arranging the first protective gasket ring 110 and the second protective gasket ring 130 at the bottom and top of a plurality of stacked gasket rings 210, and assembling the plurality of stacked gasket rings 210 through a plurality of reinforcing struts 120, the plurality of gasket rings 210 in a cylindrical structure can provide a stable winding platform for the coil at this time. Furthermore, the cooling air flow inside the chassis can provide continuous temperature control for the coil of the winding. Embodiment 3

[0034] Combined Figures 3 - 5 As shown, on the basis of Embodiment 1, a clamping groove 220 is provided on the outside of the gasket ring 210, a guiding hole 230 is provided inside the clamping groove 220, a diversion groove 240 is provided on the outside of the gasket ring 210, and the diversion groove 240 is located inside the adjacent two clamping grooves 220. Pad feet 260 that are recessed inward are provided at the top and bottom of the clamping seat 250.

[0035] By assembling a plurality of stacked gasket rings 210 on the outside of the second protective gasket ring 130, the diversion grooves 240 provided on the adjacent two gasket rings 210 can cooperate with the pad feet 260 to conduct the cooling air flow at this time. As the rotor rotates at a high speed, the high-energy accelerated electrons generated inside the chassis can avoid burning the stator assembly and the winding due to the existence of high temperature inside the chassis. Embodiment 4

[0036] Combined Figure 4 and Figure 5 As shown, on the basis of Embodiment 1, the diversion groove 240 is oval, and the diversion groove 240 is in a communicating state with the pad feet 260. Four pad feet are symmetrically distributed at one end of the clamping seat 250 close to the inside of the gasket ring 210, and the pad feet are adapted to penetrate into the inside of the clamping groove 220.

[0037] By clamping the four pad feet outside the clamping seat 250 inside the clamping groove 220, and cooperating with the reinforcing strut 120 to penetrate the guiding hole 230 and the internal slot of the pad feet, the combined clamping seat 250 will be stably installed on the outside of the gasket ring 210. At this time, the winding can obtain a stable bearing platform.

[0038] Working principle and usage process of the present utility model: A plurality of processed clamping seats 250 are uniformly installed outside the spacer ring 210 in advance. At this time, the pad feet of the clamping seat 250 are adaptively clamped inside the clamping grooves 220. At this time, the holes of the pad feet in the clamping seat 250 will communicate with the guiding holes 230, and the diversion grooves 240 will be located inside the pad feet of the clamping seat 250. At this time, the diversion grooves 240 will be in communication with the pad feet 260. Then, a plurality of reinforcing struts 120 are fixedly installed inside the first protective spacer ring 110. Then, the combined plurality of clamping grooves 220 and a plurality of clamping seats 250 are movably installed outside the reinforcing struts 120 until the plurality of spacer rings 210 are stacked into a cylindrical structure. Finally, the second protective spacer ring 130 can be fixedly installed at the tops of the plurality of reinforcing struts 120;

[0039] During use, after the wire group is wound around the outside of the clamping seat 250, the pad feet 260 provided on two adjacent clamping seats 250 can communicate with the external environment through the diversion grooves 240. As the rotor speed increases, the inside of the chassis will cooperate with the external air-cooling equipment to introduce cooling air into the diversion grooves 240 and the pad feet 260. At this time, the wire group wound around the outside of the clamping seat 250 can be continuously temperature-controlled. At this time, the wire group on the stator can avoid the problem of burning due to continuous temperature rise, and thus can protect the insulating part of the stator winding.

[0040] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
