Abstract
The utility model discloses a closed type outer rotor fan motor which comprises an outer rotor, an inner stator, an end cover and a rotating shaft. Bearings are installed between the end cover and two ends of the rotating shaft respectively, the outer rotor is integrated by direct aluminum die casting of a rotor iron core and a front end part, one end of the outer rotor is connected with the end cover through a screw, and the inner stator and the rotating shaft undergo press fitting in an interference fit mode. The closed type outer rotor fan motor reduces loss, the rotating speed is improved, the air quantity is increased, and efficiency is improved. The shaft-supported outer rotor undergoes two-end hard supporting, the two bearings are stressed evenly, the service lives of the bearings are prolonged, sealing performance is improved, and the applied range of the using environment is expanded.
Description
Technical field
The utility model relates to a kind of closo motor of external rotor fan.
Background technology
Comparing under the adverse circumstances, all adopt inner rotor motor.
1. former External rotor electric machine rotor is with the single-ended hard support of axle, causes the two bearings unbalance stress, and bearing is fragile; 2. former motor stator for outer rotator and support are that the metal interference of two kinds of unlike materials cooperates (stator material silicon steel sheet closed assembly, the die casting of support material aluminium), and be yielding and eccentric when press-fiting; 3. gapped between former External rotor electric machine rotor and support, the winding coil moisture-sensitive reached foreign material such as easily entering dust, silk wadding and the motor that arrives damage when humidity was high.
The utility model content
The utility model purpose is to provide a kind of closo motor of external rotor fan for the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The utility model closo motor of external rotor fan, comprise external rotor, internal stator, end cap and rotating shaft, be separately installed with bearing between end cap and the rotating shaft two ends, described external rotor is die cast as one by rotor core and the direct aluminium of leading section, and an end of external rotor is connected with the bullet pad by screw with end cap; Internal stator and rotating shaft interference fit press-fit.
Described rotating shaft external part be connected and fixed plate and fix with locking nut.
Along rotor shaft direction ripple is installed successively and adjusts pad and shaft block ring on described bearing, ripple is adjusted pad and is pressed in bearing and the rotating shaft, and shaft block ring is installed on the circlip groove of rotating shaft.
The loss of the utility model closo motor of external rotor fan reduces; Rotating speed improves, and air quantity increases, and efficient improves; It is that two ends are supported firmly that axle supports external rotor, and two bearings is stressed evenly, improves bearing useful life; Improve sealing property, enlarge the scope of application to environment for use.
Description of drawings
Fig. 1: the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model closo motor of external rotor fan, comprise external rotor 1, internal stator 2, end cap 3 and rotating shaft 4, be separately installed with bearing 5 between end cap 3 and rotating shaft 4 two ends, it is characterized in that described external rotor 1 is die cast as one by rotor core and the direct aluminium of leading section, an end of external rotor 1 is connected with the bullet pad by screw 7 with end cap 3 and is connected; Internal stator 2 press-fits with rotating shaft 4 interference fit.Motor lead-out wire 10 also is set on the internal stator 2.
Described rotating shaft 4 external parts be connected and fixed plate 6 usefulness locking nuts 9 and fix.
Along rotating shaft 4 directions ripple is installed successively and adjusts pad 11 and shaft block ring 12 on described bearing 5, ripple is adjusted pad 11 and is pressed in bearing 5 and the rotating shaft 4, and shaft block ring 12 is installed on the circlip groove of rotating shaft 4.
New improvement external rotor electric machine is that rotor core and the direct aluminium of leading section are die cast as one, and the bearing location hole is arranged, and is that aluminium die casting end cap connects behind the rotor; The axle interference fit of stator core and 40Cr material press-fits; External part and the connecting plate of axle are fixed with locking nut.
