Description
Technical field
The utility model relates to the square double feedback electric engine support of a kind of high strength height ventilation, belongs to compact double-fed generator or doubly-fed motor support.
Background technology
The main Problems existing of support of double feedback electric engine is in the market that structural design intensity is unreasonable, result of ventilating heat dissipation is bad.Principal mode is flange-cooled version, which is applicable to the draft type of IP54 or IP44, heat is drained on inboard wall of base by internal fan by the heat that namely motor produces, then is drained into by heat external by fin, and the double feedback electric engine of not speed change uses this support to be feasible.Because brushless dual-feed motor is variable-speed operation, when motor speed declines, the power of motor is still very large, cause the heat produced in motor to gather increase like this, now the rotating speed of internal fan declines along with motor speed and declines, the abatement of wind, if use flange-cooled support, radiating effect is very poor.Therefore, heat radiation contradiction when solving brushless dual-feed motor variable-speed operation is badly in need of.
Summary of the invention
The object of the utility model electric machine stand is to overcome above-mentioned defect, provides that a kind of structural strength is high, lightweight, good heat dissipation effect and meet the high high strength height of power of motor density and to ventilate square double feedback electric engine support.
The technical solution of the utility model: the square double feedback electric engine support of high strength height ventilation of the present utility model comprises machine base body, front end face, rear end face, machine base body is square hollow cylinder, the front end face of machine base body and rear end face have forward flange boss and the rear flange boss of interior circular hole, for installing end cap; Machine base body top rear establishes air inlet of centrifugal fan, and in the machine base body of closing on forward flange boss, two symmetrical square Inner eycle ventilating openings are established in the left and right sides, and forward upper establishes terminal box; Machine base body inside is interior circular hole riser before and after establishing, in front and back, circular hole riser is vertical with machine base body axis, its outer rim is connected to machine base body inwall, in before and after the central angles such as eight steel pipes are distributed through, circular hole riser connection forward flange boss and rear flange boss form caged, on the interior circular hole of the central angles such as eight disc interior circular hole riser before and after arranging and being welded on, the iron core of support belt wound stator, forms axial ducts simultaneously.
Eight described diameter of steel tube are Φ 30 ~ 60mm, and wall thickness is 3 ~ 6mm.
The width of eight described disc is 25 ~ 35mm, and thickness is 20 ~ 30mm, and a part for eight disc 8 embeds circular hole in the interior circular hole riser 7 in front and back, and the degree of depth is 5 ~ 8mm.
Outside described forward flange boss and rear flange boss, top is all provided with two symmetrical joint hinge earholes.
Observation window and cover plate are established in described side, machine base body rear end.
Bottom Inner eycle ventilating opening is established bottom machine base body.
The utility model electric machine stand adopts technique scheme to have the following advantages:
1, respectively to stretch a square-outside and round-inside flange boss at the front end face of machine base body and rear end face, eight hollow steel tubes are uniformly distributed and connect front and back flange raised head face, add the rigidity of whole support;
2, left and right, bottom Inner eycle ventilating opening, for motor provides circulation canal, can help motor radiating better, the desirable high value of heat load of motor, thus improve the power density of motor;
3, eight disc uniform weldings are on the riser of intermediate symmetry, base frame stiffness can be increased, be beneficial to again stator core and winding overhang heat radiation, because stator core cylindrical is equal with spoke muscle inner circle, after such press-in iron core by it with machine base body every sky, thus form axially with ventilating opening the air channel ventilated;
4, air inlet of centrifugal fan is located at support rear end face, thus can well cold wind water conservancy diversion in machine base body rear chamber, reduce the iron core of motor and winding overhang temperature.
