The base comprises a base body composed of an upper top plate and two side plates, and is characterized in that the top plate is sealed, a junction box is arranged in the middle of one of the side plates; air inlets are respectively formed on the two sides of the junction box, and air outlets are formed below the junction box; and the air inlets and the air outlets, in the same amount, are also formed on the other side plate of the two sides plate of the base and at the positions corresponding to those on former side plate; and air-in louvers and an air-out louver are respectively installed in the air inlets and the air outlets on the two side plates. According to the base provided by the invention, a top cover in an original structure is avoided, which reduces the size and weight of the motor, the appearance is more compact and attractive, and the production cost is effectively reduced.
Description
Technical field
The invention belongs to the motor manufacturing technology field, be specifically related to a kind of Y series threephase asynchronous support.
Background technology
Y series threephase asynchronous has not only satisfied the supporting needs of national economy all departments, but also has improved the interchangeability of similar products at home and abroad, is very easy to the supporting of introducing equipment and maintenance.Y series threephase asynchronous is different according to the degree of protection of its support; It is serial basically to be divided into two of IP23 (protection) and IP44 (closed); The type of cooling is IC01, promptly adopts air freely to circulate, and coolant relies on the fan of rotor to make to flow into motor.The support degree of protection of IP23 serial motors is significantly improved than J2 series, but is lower than IP44 series.
IP23 series motor bed-plate structure is as shown in Figure 1 at present, comprises top board 2 and side plate 3.As shown in Figure 2, have air-out passage 6-3 at seat top plate 2 middle parts, both sides have the first air intake passage 6-1 and the second air intake passage 6-2.As shown in Figure 1, overhead guard 4 is installed on the top board 2,4 four sidewalls of overhead guard have shutter 7, and the support side plate is installed cover plate 5, and cover plate 5 can be dismantled, so that the assembling of motor and maintenance.During the motor operation, the internal fan rotation of two ends of rotor produces air pressure, and motor internal gas enters into overhead guard from the middle air-out passage of top board, from radially intermediate louvers discharge of overhead guard.Motor internal air pressure reduces, and extraneous air enters into motor internal from overhead guard air inlet through hollow shaft mouth, and motor is cooled off.This structure finds that in application process comparatively practical for 2 utmost point motors more than the big seat No. H500, because its motor speed is high, fan air pressure is big, adopts the overhead guard form to carry out air circulation, and the support side plate can effectively reduce vibration with cover plate for sealing, reduces noise.But for the motor below the seat No. H500, because its motor speed is not high, Oscillation Amplitude is little, noise is low, if adopt the overhead guard form to carry out air circulation, has not only increased manufacturing cost, and causes that electric machine structure is too fat to move, volume is excessive.
Summary of the invention
For the existing manufacturing cost of Y series threephase asynchronous support that overcomes present IP23 protection level increases, the technical problem that electric machine structure is too fat to move, volume is excessive, this practicality is new
Type provides a kind of compact conformation, the desirable Y series threephase asynchronous support of cooling effect.
For realizing above-mentioned technical purpose; The technical scheme that the present invention adopts is: Y series threephase asynchronous support, comprise machine base body, and machine base body comprises upper plate and both sides side plate; It is characterized in that: described seat top plate sealing; The middle part of a side side plate is provided with terminal box therein, in the both sides of terminal box air inlet is set respectively, and the below of terminal box sets out the air port; On the side plate of support opposite side with on this side side plate correspondence position the air inlet and the air outlet of same quantity being set, air intake shutter and air-out shutter are installed respectively on air inlet on the side plate of both sides and the air outlet.
Described seat top plate is a complete sheet material.
Offer air intake, air-out passage on the described seat top plate, adopt cover closure on the passage.
Described air intake shutter, its air-inlet window blade is downward-sloping, and blade surface is the intrados structure.
Described air-out shutter, its air outlet window blade is downward-sloping, and blade surface is the extrados structure.
Adopt Y series threephase asynchronous support provided by the invention, during the motor rotation, air gets into motor internal from the support both sides, in the middle of support, discharges, and the path of air circulation is short, and air pressure is big, and inlet and outlet cools off motor at middle part unshakable in one's determination effectively.Cancelled the overhead guard of original structure, reduced motor volume and weight, profile is compact more attractive in appearance, can effectively reduce manufacturing cost.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 3; Y series threephase asynchronous support; Comprise machine base body 1, machine base body 1 comprises upper plate 2 and both sides side plate 3, and correspondence is provided with air intake shutter and air-out shutter (structure that has terminal box one side side plate shown in the figure) are installed on the side plate 3 of both sides.
As shown in Figure 3; Air intake shutter on every side side plate is divided into the first air intake shutter 7-1 and the second air intake shutter 7-2; Two air intake shutters are near the two ends of machine base body; Between the two air intake shutters of a side side plate installation connection box 8 is set therein, in the bottom of terminal box 8 air-out shutter 7-3 is installed, air intake shutter and air-out shutter are respectively through air inlet and air outlet and base inner perforation.
As shown in Figure 3, seat top plate 2 is an enclosed construction.
When rotor rotation is worked; Owing on the rotor internal fan is housed; The blast forced air of utilizing fan to produce gets into motor internal by the first air intake shutter 7-1 on the side plate of both sides and the second air intake shutter 7-2, drives heat then and is discharged by air-out shutter 7-3.Air intake shutter and air-out shutter can be for convenience detach, so that the assembling of motor and maintenance.This version is compared with the prior motor support and has been omitted overhead guard, has reduced motor volume and weight, and profile is compact more attractive in appearance, and during cooling, the path of air circulation is short, and air pressure is big, and inlet and outlet can cool off motor at middle part unshakable in one's determination effectively.
Fig. 4, Fig. 5 show the structure of air-out shutter, and shutter is made up of many air outlet window blade 9-1.As shown in Figure 5, when preventing work, get into motor internal for preventing rainwater and other foreign material, air outlet window blade 9-1 tilts downwards when arranging, and for the motor internal air is discharged smoothly, air outlet window blade 9-1 surface is the extrados structure simultaneously.
