Abstract
The utility model proposes a novel fan motor, which comprises an inner stator, external rotor and a wind leave. The key points are that a guiding bar 4, an external rotor fixation ring 5 and the wind leave1 in the gap of the external rotor overlapped silicon steel plate 2 of the fan motor are died by metal aluminium at one time. A rotary shaft 3 is fixed in the center of the external rotor fixation ring 5. A balance hole 6 is arranged in outer edge of the external rotor fixation ring 5. A novel motor (or fan) member is formed by the external rotor and the fan leave of fan of the fan motor. The proposal of the utility model reduces the manufacture working sequence of the wind leave, improves the balance degree and precision of the fan and reduces the fan vibration noise by more than 10 percent.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of novel fan electromotor.
Background technology
Present fan electromotor generally is divided into two kinds of forms, i.e. Chang Yong inner rotor core and relatively more novel now outer-rotor structure.Chang Yong inner rotor core adopts external rotor (being internal stator) structure can reduce the length of embedded enamelled wire relatively, and used coil has only original enamelled wire 1/3, greatly reduces the cost of raw material.Because loop length significantly reduces, but the number of turn is constant, has reduced the internal loss of fan like this under the constant situation of inductance, and the efficient of fan and life-span have been improved more than 30%.Add in manufacturing in addition and also reduced manufacturing procedure man-hour, make efficiency has been improved about 50%.So adopting comparatively novel external rotor electric machine is the manufacturing fashion trend of fan.Generally before this fan blade riveted joint or point were welded on the steel bushing when external rotor fan electromotor is made, and then external rotor was pressed in the steel bushing, fan blade and external rotor are combined securely.The fan of Xing Chenging has higher efficient and useful life like this.But the machining accuracy that this kind external rotor fan is had relatively high expectations when the assembling fan blade, and manufacturing procedure is also more loaded down with trivial details.
Summary of the invention
The utility model proposes a kind of novel fan electromotor and be the more loaded down with trivial details deficiency of operation in order to overcome existing external rotor fan and to make, propose a kind of make efficiency height, novel fan electromotor that dynamic balance performance is good.
The utility model is achieved in that the fan electromotor that is made of internal stator, external rotor and fan blade, sliver, external rotor retainer ring and fan blade in the stacked silicon steel sheet of its fan electromotor external rotor space is an integral body that constitutes with metallic aluminium, the centre of rotor retaining ring also is fixed with a rotating shaft outside, and the outer rim of rotor retaining ring is provided with balancing hole outside.Since the utility model when making with rotor and fan blade with metallic aluminium with the disposable die cast of mould, so can design high performance fan blade shape according to aerodynamic principle more easily, make air quantity, blast and noise all reach optimum.Reduced the manufacturing procedure of fan blade, the degree of balance of fan and precision also improve greatly, make the fan vibration noise reduce more than 10%.Also directly increase the conducting sectional area of external rotor aluminium ring in addition, improved the electric property of rotor.Compare the former plastic blade that generally adopts, the utility model has more strengthened high-and low-temperature resistance and anti-aging degree, and corrosion resistance is strong, more adapts to adverse circumstances.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Fig. 2 is that the A-A of Fig. 1 is to profile.
Embodiment
In conjunction with Fig. 1 Fig. 2, during concrete the making, sliver 4, external rotor retainer ring 5 and fan blade 1 in the stacked silicon steel sheet of fan electromotor external rotor 2 spaces is that the whole metallic aluminium that adopts constitutes with the disposable die casting of mould, the centre of rotor retaining ring 5 also is fixed with a rotating shaft 3 outside, and the outer rim of rotor retaining ring 5 is provided with balancing hole 6 outside.Thereby form a kind of external rotor of fan electromotor and New-type electric machine (or fan) member that the fan fan blade combines.8 balancing holes 6 are evenly distributed on the end face of external rotor retainer ring 5.Certainly, the quantity of balancing hole 6 should be according to the size of external rotor diameter and increase and decrease to some extent.
Claims (2)
1, a kind of novel fan electromotor, constitute by internal stator, external rotor and fan blade, it is characterized in that: the sliver (4) in the stacked silicon steel sheet of fan electromotor external rotor (2) space, external rotor retainer ring (5) and fan blade (1) are an integral body that constitutes with metallic aluminium, the centre of rotor retaining ring (5) also is fixed with a rotating shaft (3) outside, and the outer rim of rotor retaining ring (5) is provided with balancing hole (6) outside.
2, a kind of novel fan electromotor according to claim 1, it is characterized in that: said balancing hole (6) is 8.
