Description
Technical field
The utility model is a kind of stator and rotor of wind power generator core structure, belongs to the technical field of structures of motor.
Background technology
In recent decades, the development that wind generating technology is advanced by leaps and bounds.China turns into global first wind-powered electricity generation country.
Generator is as the core component of wind-powered electricity generation industry, and product quality restricts the development of wind-powered electricity generation industry, especially to generator temperature rise and knot
Structure proposes requirements at the higher level.
The content of the invention
The utility model is exactly to design for problem present in above-mentioned existing industry requirement and technology and provide one kind
Stator and rotor of wind power generator core structure, it is the purpose is to solve stator and rotor iron core DE end temperature rises low, and the temperature rise of NDE ends is asked
Topic, so as to realize the purpose for reducing generator temperature rise.
The purpose of this utility model is achieved through the following technical solutions：
This kind of stator and rotor of wind power generator core structure, the stator core (10) of the wind-driven generator are embedded in cabin (1)
Interior, rotor core (9) and centrifugal impeller (2) are nested on main shaft and are fixed on composition generator main body in stator core (10),
Hot-air in the lower section of generator main body placement air cooler (4) completion wind powered generator system, cabin (1) is in centrifugation leaf
In the presence of taking turns (2), air cooler (4) is flowed through by air outlet (3) and has carried out heat exchange with air cooler (4), after heat exchange
Cold air enters cabin (1) through air intake vent (5), while cold air flows through rotor axial ventilation in the presence of centrifugal impeller (2)
Road (6), rotor ventilation groove (7), stator ventilation slot (8) flow back entered back into centrifugal impeller (2) afterwards, form the cooled of motor
Journey, during being somebody's turn to do, cold air carries out heat exchange with rotor core (9), stator core (10), it is characterised in that：Rotor ventilation groove
(7), stator ventilation slot (8) uses uneven arrangement, from rotor axial ventilating duct (6) to centrifugal impeller (2) direction, the arrangement
Mode is followed successively by：Preceding four iron legs core width is 80mm~100mm, middle five iron leg core width be 50mm~70mm, 8 sections below
Iron core width is 35mm~50mm.
It is relatively low into the air temperature of cabin (1) through DE ends air intake vent (5) in technical solutions of the utility model, cooling
Ability is stronger, therefore every section of core length close to DE ends suitably lengthens, i.e. ventilation slot arrangement is relatively dredged；And cold air passes through axial direction
After ventilating duct (6) flows through a segment distance, air temperature is stepped up, and cooling capacity weakens, to improve cold air to NDE ends
The cooling effect of rotor core (9), stator core (10), gradually reduces every section of core length, i.e., stator and rotor ventilation slot arrangement compared with
It is close, cooling capacity of the cold air to NDE ends rotor core (9), stator core (10) is improved, so as to form non-uniform ventilation
Groove, to realize that stator and rotor iron core both ends obtain uniform temperature rise effect.
Brief description of the drawings
Fig. 1 is the schematic diagram of stator and rotor of wind power generator core structure described in the utility model
Embodiment
The utility model is further described below with reference to drawings and examples：
Referring to shown in accompanying drawing 1, this kind of stator and rotor of wind power generator core structure, the stator core 10 of the wind-driven generator is inlayed
In cabin 1, rotor core 9 and centrifugal impeller 2 are nested on main shaft and are fixed in stator core 10 and form generator main
Body, the hot-air in the lower section of the generator main body placement completion wind powered generator system of air cooler 4, cabin 1 is in centrifugal impeller 2
In the presence of, air cooler 4 is flowed through by air outlet 3 and has carried out heat exchange with air cooler 4, the cold air after heat exchange is through entering
Air port 5 enters cabin 1, while cold air is in the presence of centrifugal impeller 2, flow through rotor axial ventilating duct 6, rotor ventilation groove 7,
Backflow has entered back into centrifugal impeller 2 after stator ventilation slot 8, forms the cooling procedure of motor, during being somebody's turn to do, cold air and rotor iron
Core 9, stator core 10 carry out heat exchange, take away caused heat in generator operation engineering, realize controlled motor temperature rise
Purpose, it is characterised in that：Rotor ventilation groove 7, stator ventilation slot 8 use uneven arrangement, from rotor axial ventilating duct 6 to centrifugation
The direction of impeller 2, the arrangement mode are followed successively by：Preceding four iron legs core width is 80mm~100mm, middle five iron leg core width are
50mm~70mm, 8 iron leg core width are 35mm~50mm below.
The utility model structure is characterised by that the air temperature for entering cabin 1 through DE ends air intake vent 5 is relatively low, cools down energy
Power is stronger, therefore every section of core length close to DE ends suitably lengthens, i.e. ventilation slot arrangement is relatively dredged；And cold air passes through axial direction and led to
After air channel 6 flows through a segment distance, air temperature is stepped up, and cooling capacity weakens, to improve cold air to NDE ends rotor
The cooling effect of iron core 9, stator core 10, every section of core length is gradually reduced, i.e. stator and rotor ventilation slot arrangement is closeer, improves
Cold air is to the cooling capacity of NDE ends rotor core 9, stator core 10, so as to form non-uniform ventilation slot, to realize
The characteristics of stator and rotor iron core (9,10) the utility model is：Ventilation slot non-uniform Distribution, it can obtain stator-rotor iron core uniform
Temperature rise effect.
