Portion.Integrate Design radiating mode in existing motor stator for outer rotator is to increase built-in heat dissipation area, reduces inside
Heat absorption area causes heat not to be transmitted to outside electric machine casing quickly, is affected so as to cause motor performance, and efficiency is not
It can maximize.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of end cap of external rotor electric machine, energy
It is enough integrally formed the cylinder and ontology of end cap by the good die casting aluminium of thermal conductivity, and ventilation hole is flowed by the increase of the first pore
With the flow velocity of the air of the second pore, the heat in motor is constantly taken away using the air of flowing, effectively enhancing die-cast aluminum cover
Heat dissipation effect, so that motor is cooled down rapidly.
To achieve the above object, the utility model proposes a kind of end cap of external rotor electric machine, including die casting aluminium cylinder and
It is equipped in die casting aluminium ontology, the die casting aluminium cylinder and die casting aluminium ontology along the perforative centre bore in central axes, the center
First bearing seat and second bearing seat are respectively equipped on the both ends hole wall in hole, the center of the die casting aluminium ontology is additionally provided with in
Ventilation hole, the die casting aluminium cylinder are equipped in the threaded hole that heart hole connects, the die casting aluminium cylinder and die casting aluminium ontology
It is equipped with that several are connected with ventilation hole and the other end leads to the first pore of centre bore, the die casting aluminium ontology is equipped with
Several be connected with ventilation hole and the other end lead to end cap outside the second pore.
Preferably, the first bearing seat and second bearing seat are respectively positioned in the centre bore of die casting aluminium column body, institute
That states first bearing seat is located at end of the die casting aluminium cylinder far from die casting aluminium ontology, and the second bearing seat is located at close to die casting
The end of aluminium ontology.
Preferably, the aperture of first pore is gradually reduced from close to central hole to far from central hole.
Preferably, the die casting aluminium cylinder and die casting aluminium ontology are structure as a whole.
The utility model has the beneficial effects that the utility model is integrally formed the column of end cap by the good die casting aluminium of thermal conductivity
Body and ontology, and by the first pore increase flow into ventilation hole and the second pore air flow velocity, using flowing air not
The disconnected heat taken away in motor, effectively enhances the heat dissipation effect of die-cast aluminum cover, motor is made to cool down rapidly.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram of the end cap of external rotor electric machine of the utility model；
In figure: 41- die casting aluminium cylinder, 42- die casting aluminium ontology, 43- centre bore, 44- first bearing seat, 45- second bearing
Seat, 46- ventilation hole, the first pore of 47-, the second pore of 48- and 49- threaded hole.
[specific embodiment]
Refering to fig. 1, a kind of end cap of external rotor electric machine of the utility model, including die casting aluminium cylinder 41 and die casting aluminium ontology
42, the die casting aluminium cylinder 41 and die casting aluminium ontology 42 are interior equipped with along the perforative centre bore 43 in central axes, the centre bore
First bearing seat 44 and second bearing seat 45 are respectively equipped on 43 both ends hole wall, the center of the die casting aluminium ontology 42 is also set
There is the threaded hole 49 to connect with centre bore 43, be equipped with ventilation hole 46 in the die casting aluminium cylinder 41 and die casting aluminium ontology 42,
The die casting aluminium cylinder 41 is connected equipped with several with ventilation hole 46 and the other end leads to the first pore of centre bore 43
47, the die casting aluminium ontology 42 be equipped with several be connected with ventilation hole 46 and the other end lead to end cap outside second
Pore 48, the first bearing seat 44 and second bearing seat 45 are respectively positioned in the centre bore 43 inside die casting aluminium cylinder 41, described
First bearing seat 44 is located at end of the die casting aluminium cylinder 41 far from die casting aluminium ontology 42, and the second bearing seat 45, which is located at, to be leaned on
The end of nearly die casting aluminium ontology 42, the aperture of first pore 47 from from centre bore 43 to far from centre bore 43 by
Decrescence small, the die casting aluminium cylinder 41 and die casting aluminium ontology 42 are structure as a whole.
Utility model works process:
During the work time, the air of flowing enters a kind of end cap of external rotor electric machine of the utility model from the first pore 47
In end cap, since the aperture of the first pore 47 constantly reduces, so that the air velocity entered increases, subsequent air is along ventilation hole
