Abstract
The utility model discloses a motor with a uniformly-distributed ventilation type protective cover structure. The motor comprises motor stators, motor rotors and a motor housing. Motor air gaps are formed between the motor stators and the motor rotors. The motor stators are fixed on an inner wall of the motor housing. An end portion of the motor housing is provided with a ventilation protective cover. The motor rotors are disposed on the ventilation protective cover. The ventilation protective cover has a structure of a round disc. An enclosed air channel is arranged on the ventilation protective cover. The enclosed air channel is equipped with air inlets and air outlet holes. The air outlet holes rightly face the motor air gaps. Blowers are disposed at the air inlets. A circulation air path is combined with the motor protective cover, cooling air, via the protective cover, is directly blown toward a heating part, and the air quantity can be adjusted through the additionally-arranged blowers, thereby greatly improving a cooling effect of the heating part of a motor. The protective cover is made from glass fiber reinforced plastic, and exhibits an excellent mechanical property and an excellent anticorrosion property. Meanwhile, the production cost for the motor is lowered.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of motor with uniform ventilated type protective roof structure.
Background technology
High-rating generator must cool off in order to guarantee failure-free operation and to take full advantage of for the purpose of its output capacity, so that the heat that the winding in stator and the rotor and magnet are produced dissipates.In the generator operation process, the energy loss that is produced by magnetic force and electric energy can convert heat at generator, cause the each several part temperature to raise, cause thus the impedance of coil to raise, shadow is to generating efficiency, can cause simultaneously the damage of conductive member insulating barrier and the damage of other members, thereby effectively cooling is one of main miscellaneous function of generator.
What motor adopted at present is electric machine structure spare inner ventilation, because structural member inside is airtight, is difficult to accomplish inner antirust, anti-corrosive processing, air directly enter structural member inside to the structural member life-span cause very large shadow to, and windage is large during wind process structural member, and shadow is to the cooling effect of motor
The utility model content
The technical problem that the utility model solves is: by improving the structure of electric machine structure spare, improve the cooling effect of motor.
For reaching this purpose, the utility model by the following technical solutions:
A kind of motor with uniform ventilated type protective roof structure, it comprises motor stator, rotor, electric machine casing, form motor gas-gap between described motor stator and the rotor, described motor stator is fixed on the electric machine casing inwall, described electric machine casing end is provided with ventilation protective cover, described rotor is arranged on the ventilation protective cover, described ventilation protective cover becomes disc-shaped structure, be provided with airtight air channel on the described ventilation protective cover, be provided with air inlet and exhaust vent on the described airtight air channel, described exhaust vent is over against motor gas-gap, and described air inlet place is provided with air blast.
Further, described ventilation protective cover adopts glass-reinforced plastic material to make.
Further, described exhaust vent is the tubular structure that stretches out on the ventilation protective cover.
Further, described airtight air channel is two, all becomes the semi-annular shape structure, and an air inlet is set on each airtight air channel, and described exhaust vent is a plurality of uniform on the circumference of airtight air channel.
The beneficial effects of the utility model are: this design adopts an end air intake, and one brings out the one-way circulation of wind, and cooling system is simple, efficient is high.The circulation wind path combines with motor shield, and cooling air directly blows to heat generating components through protective cover, and Air Quantity Required can be by adding Fan Regulation, the cooling effect of the body that improved greatly that the motor feels hot.What protective cover was used is glass-reinforced plastic material, and satisfactory mechanical property, antiseptic property are good, has also reduced the motor production cost simultaneously.This wind path cooling system is effective for the low speed large-size machine, can be used in the bad environment of the air qualities such as humid air, coastal salt fog air.

Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Such as Fig. 1, shown in 2, in the present embodiment, a kind of motor with uniform ventilated type protective roof structure described in the utility model, it comprises motor stator 1, rotor 2, electric machine casing 3, form motor gas-gap 4 between described motor stator 1 and the rotor 2, described motor stator 1 is fixed on electric machine casing 3 inwalls, described electric machine casing 3 ends are provided with ventilation protective cover 5, described ventilation protective cover 5 adopts glass-reinforced plastic material to make, satisfactory mechanical property, antiseptic property is good, also reduced simultaneously the motor production cost, described rotor 2 is arranged on the ventilation protective cover 5,5 one-tenth disc-shaped structures of described ventilation protective cover, be provided with airtight air channel 6 on the described ventilation protective cover 5, be provided with air inlet 7 and exhaust vent 8 on the described airtight air channel 6, described airtight air channel 6 is two semi-annular shape structures on the ventilation protective cover 5, one side is respectively arranged with an air intake 7 on described two airtight air channels 6, be distributed with the protruding exhaust vent 8 of a plurality of circular tubuloses on the circumference that another side and described motor gas-gap 4 face, described air inlet 7 places are provided with air blast 9.
By air blast 9 with cooling air in air inlet 7 blows into ventilation protective cover 5, wind is ventilation protective cover 5 interior flowing, and through exhaust vent 8 time, discharged by exhaust vent 8, because exhaust vent 8 is over against motor gas-gap 4, cooling airflow cools off through 4 pairs of heaters of motor gas-gap, then hot blast is discharged from the motor other end
This wind path cooling system is effective for the low speed large-size machine, and ventilation protective cover 5 is glass-reinforced plastic material, corrosion can not occur, and can be used in the bad environment of the air qualities such as humid air, coastal salt fog air.
What need statement is; above-mentioned embodiment only is preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with easily expected or replacement all should be encompassed in the protection range of the present utility model.
