The wind shielding plate is reasonable in structure, a wind path is more smooth after the motor rotates, the air volume through a motor stator and a rotor can be greatly increased, the temperature rise of the motor can be greatly lowered, the heat radiating effect of the motor can be significantly improved, the efficiency of the motor can be greatly improved, the assembling is convenient, and the original assembling method of the motor is not changed.
Description
Technical field
The utility model relates to a kind of inner fan structure threephase asynchronous deep bead, for inner fan structure threephase asynchronous center height, is specifically the deep bead that 315-4 is extremely used, and belongs to motor technology field.
Background technology
Burn-down of electric motor is that the temperature extremes that the accumulation temperature of motor winding or bearing can bear over motor causes.Along with the properties of the rising motor of temperature can significantly decrease.Therefore the temperature rise at electromechanics trade control motor is a standard considering motor performance.
The mode of reduction electric machine temperature rise has a variety of, and the ventilating path that wherein changes motor is a kind of mode of simple reduction temperature rise, so the mode in improvement motor ventilation path is to avoid the too high a kind of mode that causes that motor overheating burns out of motor temperature.Motor reduces the properties that temperature rise can improve motor accordingly.Reducing temperature rise can effectively raise the efficiency to a certain extent.
In existing motor, aeration structure is single, and wind path structure is unreasonable, there is no good radiating effect, so increase deep bead, change the wind path structure of motor, increase wind by the air quantity of motor stator and rotor, thereby can effectively reduce the performance of the temperature rise raising motor of motor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of inner fan structure threephase asynchronous deep bead is provided, and changes the wind path structure of motor, strengthens the radiating effect of motor, thereby improves the performance of motor.
The technical scheme providing according to the utility model, inner fan structure threephase asynchronous comprises outer ring and inner ring with deep bead, inner ring is arranged in outer ring, it is characterized in that: the air-ducting ring by left end between outer ring and inner ring links into an integrated entity; Outer ring outer surface is provided with a plurality of connecting holes, and a plurality of connecting holes are along the circumferential direction uniformly distributed.
Further, air-ducting ring is tubaeform, and air-ducting ring from left to right diameter diminishes gradually.
Further, the included angle A of air-ducting ring sidewall and vertical line is 0 ~ 90 °.
Further, connecting hole is 4
Further, connecting hole is Long Circle.
Further, outer ring, air-ducting ring and inner ring adopt glass-reinforced plastic material to make.
Compared with the prior art the utility model has the following advantages:
The utility model is rational in infrastructure, after motor rotation, can make wind path more smooth, can greatly increase by the air quantity of motor stator and rotor; Can greatly reduce electric machine temperature rise, can greatly improve motor radiating effect, can greatly improve the efficiency of motor; Assembling mode easy to assembly, need not to change original motor.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 be in Fig. 1 K to view.
Description of reference numerals: 1-outer ring, 2-air-ducting ring, 3-inner ring, 4-connecting hole.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises outer ring 1 and inner ring 3, and inner ring 3 is arranged in outer ring 1.
Air-ducting ring 2 by left end between outer ring 1 and inner ring 3 links into an integrated entity, and air-ducting ring 2 is tubaeform, and air-ducting ring 2 from left to right diameter diminishes gradually.Air-ducting ring 2 major diameter openends are wind-guiding outlet, and air-ducting ring 2 minor diameter openends are wind-guiding import.Air-ducting ring 2 minor diameter openends are identical with inner ring 3 diameters.
The included angle A of described air-ducting ring 2 sidewalls and vertical line is 0 ~ 90 °.
Described outer ring 1 outer surface is provided with a plurality of connecting holes 4, and a plurality of connecting holes 4 are along the circumferential direction uniformly distributed.Described connecting hole 4 is Long Circle.
Described outer ring 1, air-ducting ring 2 and inner ring 3 adopt glass-reinforced plastic material to make, and very light, cost is lower.
In embodiment mono-as shown in Figure 1 and 2, connecting hole 4 is 4, the length dimension h6=23mm of connecting hole 4, the width dimensions h7=6.5mm of connecting hole 4.
Air-ducting ring 2 height dimension h4=27mm, air-ducting ring 2 left ends are to the distance h 5=57mm of inner ring 3 right-hand members.Air-ducting ring 2 major diameter openend diameter phi d1=φ 530mm.Air-ducting ring 2 minor diameter openend diameter phi d2=φ 380mm.
The utility model is when work, and the wind of fan enters by air-ducting ring 2 minor diameter openends, and along flaring air-ducting ring 2, entering air-ducting ring 2 major diameter openends derives.It can make wind path more smooth after motor rotation, can greatly increase wind by motor stator and rotor, can greatly reduce electric machine temperature rise, can greatly improve motor radiating effect, can greatly improve the efficiency of motor, and assembling mode easy to assembly, that need not change original motor.
