Abstract
The utility model discloses a kind of inside wind loop structures of enclosed motor, including shaft, rotor, Stator and electrical machine shell, centrifugal fan is provided in the intracorporal shaft of the motor casing, several muscle are arranged between the stator and electric machine casing to connect stator with electric machine casing, ventilation hole is formed between muscle and muscle, is provided with tube-axial fan in ventilation hole.The utility model has the advantages that making wind circulation, uniform heat distribution, it is easier to shed by shell inside motor using centrifugal fan in such a way that tube-axial fan combines.
Description
Technical field
The utility model relates to motor radiating field, the inside wind loop structure of especially a kind of enclosed motor.
Background technique
The motor protection effect of closed surface radiating is good, and electrical machinery life is long, but because the heat inside motor is not easy
It sheds, the power density of motor cannot be done too high, cause the volume of motor excessive, motor inner heat is uneven, air stream
Dynamic property is poor, causes heat to be assembled, is the main cause that enclosed motor radiates bad.Currently, common cooling method is
Increase cooling wind blade on motor, however cooling wind blade would generally use plate leaf, the air quantity very little that plate leaf generates, heat dissipation effect
Fruit is poor.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of inside wind circulation of enclosed motor
Structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of inside wind circulation knot of enclosed motor
Structure, including shaft, rotor, Stator and electrical machine shell are provided with centrifugal fan in the intracorporal shaft of the motor casing, described
Stator and electric machine casing between several muscle be set connect stator with electric machine casing, form ventilation hole between muscle and muscle, divulge information
Tube-axial fan is provided in hole.
Specifically, the centrifugal fan is located at the side of the collector ring of motor.
Specifically, the outer diameter of the centrifugal fan is greater than the outer diameter of the rotor of motor.
Specifically, the centrifugal fan includes blade, transverse plane, positioning hole seat and connection wheel hub, the blade
For arc, it is uniformly arranged on transverse plane, the transverse plane is annular in shape and is connect by connection wheel hub with positioning hole seat,
It is provided in positioning hole seat for being connected with the rotating shaft through-hole.
Specifically, the tube-axial fan is fixed in ventilation hole.
The utility model has the advantage that (1), keeps the inner air circulation of enclosed motor more smooth, and heat is not easy
Aggregation makes wind circulation inside motor using centrifugal fan in such a way that tube-axial fan combines, and heat distribution is equal
It is even, it is easier to be shed by shell.
(2), motor internal heat sheds more easily by shell, increases electrical machinery life.
Detailed description of the invention

Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to
It is as described below.
As shown in Fig. 1 ~ 3, a kind of inside wind loop structure of enclosed motor, including shaft 2, rotor, stator 3 and motor
Shell 4 is provided with centrifugal fan 1 in the shaft 2 in the electric machine casing 4, between the stator 3 and electric machine casing 4
Several muscle 6 are set and connect stator 3 with electric machine casing 4, forms ventilation hole between muscle 6 and muscle 6, is provided with axial-flow type in ventilation hole
Fan 7, tube-axial fan external power supply.
Further, the centrifugal fan 1 is located at the side of the collector ring of motor.
Further, the outer diameter of the centrifugal fan 1 is greater than the outer diameter of the rotor of motor.
Further, the centrifugal fan 1 includes blade 9, transverse plane 8, positioning hole seat 11 and connection wheel hub 10, institute
The blade 9 stated is arc, is uniformly arranged on transverse plane 8, forms air outlet between adjacent blades, the transverse plane 8 is in
It is circular and connect by connection wheel hub 10 with positioning hole seat 11, it is air inlet between transverse plane and positioning hole seat, positioning hole seat
The through-hole for connecting with shaft 2 is provided in 11, blade falls into cambered design using poly- press, can generate a high pressure in recess
Flow area is thrown away through air outlet, forms the air-flow of high pressure when high pressure is acted on through centrifugal force, and the effect of heat dissipation is significantly increased, into
The air-flow in air port is continuously replenished to higher-pressure region, to form a centrifugal high pressure air duct, while tube-axial fan is by the air-flow of high pressure
The other side inside motor is blowed to by ventilation hole, forms the air-flow of circulation, air is allowed to rise in the closed chamber indoor circulation of motor
Come, make the heat of the main heater such as coil, conducting bar of motor be not easy to assemble, advantageously reduce the temperature of motor,
Further, the tube-axial fan 7 is fixed in ventilation hole.
The above, the only preferred embodiment of the utility model, not do limit in any form to the utility model
System.Anyone skilled in the art, in the case where not departing from technical solutions of the utility model ambit, all using above-mentioned
The technology contents make many possible changes and modifications to technical solutions of the utility model, or be revised as equivalent variations etc.
Imitate embodiment.Therefore, all contents without departing from technical solutions of the utility model, the technology according to the utility model is to the above reality
Any change modification, equivalent variations and modification that example is made are applied, the protection scope of the technical program is belonged to.
