Background technique
Currently, energy-saving efficient motor is widelyd popularize in the whole world, China also sets up " civilian-oriented project high efficiency motor " popularization already
Catalogue, the promotion for accelerating electric efficiency is trend of the times.And high efficiency motor portion very little in the market, more for IP23 motor
It is that low efficiency, volume are big, cooling effect is bad, warm raising, serious to restrict industrial high speed development.In order to improve the efficiency of motor,
The loss of motor must be just reduced, wind friction loss is as one of five lossies, ventilating and cooling component of the fan as motor, operating
When, loss is not only generated, but also increase the overall length of motor, expands the volume of motor.
Summary of the invention
It is above-mentioned the purpose of the present invention is overcoming the problems, such as, a kind of wind path structure of IP23 high efficiency motor is provided, structure is closed
It is reason, compact and reasonable, easy to implement, every good cooling results.
According to technical solution provided by the invention, the wind path structure of the IP23 high efficiency motor, including it is casing, shaft, fixed
Son, rotor, terminal box and the drive end bearing bracket and rear end cap that are mounted on casing both ends, the stator are mounted in casing, rotor peace
In shaft, terminal box is mounted on the side of casing；The rotor is equipped with rotor fan blade；The drive end bearing bracket and stator and turn
It is equipped with front wind screen between son, rear wind-break panels are equipped between the rear end cap and stator and rotor；The drive end bearing bracket and rear end cap
It is equipped with air inlet, the side of casing is equipped with air outlet.
Further, the air outlet is equipped with ventilation web plate.
Further, the side of the casing is equipped with wire outlet seat, and terminal box is mounted on wire outlet seat.
Further, the front wind screen and rear wind-break panels are made using glass steel material one-pass molding.
Further, the front wind screen and rear wind-break panels are pyramidal, and the upper inner diameter of frustum is greater than rotor fan blade
Outer diameter.
Further, the mesh size of the ventilation web plate is 8mm × 8mm.
Further, the air inlet is strip.
The beneficial effects of the present invention are: structurally reasonable, compact and reasonable, easy to implement, multiple ventilation openings and ventilation web plate,
Form cooling air duct, good cooling results；Motor does not fill fan, greatly reduces wind friction loss, greatly improves the efficiency of motor.

Specific embodiment
Below with reference to specific drawings and examples, the invention will be further described.
It is as shown in Figure 1, 2: the wind path structure of IP23 high efficiency motor, including casing 5, shaft 1, stator 6, rotor 7, terminal box
9 and it is mounted on the drive end bearing bracket 2 and rear end cap 12 at 5 both ends of casing, wherein stator 6 is mounted in casing 4, and rotor 7 is mounted on shaft
On 1, terminal box 9 is mounted on the side of casing 5.It is equipped with rotor fan blade 8 on rotor 7, is different from and inside and outside wind is set in shaft
The structure of fan, reduces wind friction loss, improves electric efficiency, while motor axial direction overall length shortens, outer dimension greatly reduces.?
It is equipped with front wind screen 3 between drive end bearing bracket 2 and stator 6 and rotor 7, rear wind-break panels are equipped between rear end cap 12 and stator 6 and rotor 7
10；Drive end bearing bracket 2 and rear end cap 12 are equipped with air inlet 13, and air inlet 13 can be in long strip, is clouded in drive end bearing bracket 2 and rear end cap
12(is as shown in Figure 2,3), air outlet is equipped in the side of casing 5.
Specifically, being equipped with ventilation web plate 11 at air outlet.As shown in figure 4, the mesh size of ventilation web plate 11 is 8mm
× 8mm, it is ensured that the circulation of wind path guarantees cooling effect and meets requirement of shelter.Wire outlet seat, wiring are equipped in the side of casing 5
Box 9 is mounted on wire outlet seat, facilitates the left outlet and right outlet of motor.Front wind screen 3 and rear wind-break panels 10 utilize glass steel
Matter one-pass molding is made, and ensure that light weight, intensity are high, the requirement being easily installed.Front wind screen 3 and rear wind-break panels 10 are cone
Mesa-shaped, the upper inner diameter of frustum are greater than the outer diameter of rotor fan blade 8, it is ensured that the circulation of wind path guarantees cooling effect.
Working principle: as shown in Figure 1, 2, when motor operates, shaft 1 drives rotor fan blade 8 to rotate, and wind is from 2 He of drive end bearing bracket
The strip air inlet of rear end cap 12 enters, and cools down through stator 6 end of the rotor fan blade 8 to motor two sides, in front wind screen 3
6 end of stator of motor two sides is cooled down again with wind under the action of rear wind-break panels 10, subsequently into casing 5 and stator 6
Gap, by 5 air outlet of casing and ventilation web plate 11 and go out, formation cooling air duct, good cooling results.
