IP23 Series Motors stand structure comprises top board 2 and side plate 3 as shown in Figure 1 at present.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 large seat No. H500, because its motor speed is high, fan air pressure is large, 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 the 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 solution adopted in the utility model is: Y-series threephase asynchronous support, comprise machine base body, 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 arranges 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; Air inlet and the air outlet of same quantity are set with this side side plate correspondence position on the side plate of support opposite side, air intake shutter and air-out shutter are installed respectively on the 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 feed shutter window, 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.
The Y-series threephase asynchronous support that adopts the utility model to provide, during the motor rotation, air enters motor internal from the support both sides, discharge in the middle of support, the path of air circulation is short, and air pressure is large, inlet and outlet cools off motor effectively at middle part unshakable in one's determination.Cancelled the overhead guard of original structure, reduced motor volume and weight, profile is more compact attractive in appearance, can effectively reduce manufacturing cost.
