Abstract
The utility model discloses a DC ceiling fan motor external rotor comprising a housing, a rotor body, a magnetic tile, and an external rotor upper shell and an external rotor lower shell which are used for fixing the magnetic tile. The magnetic tile sleeves the external part of the rotor body. The external rotor upper shell and the external rotor lower shell are provided with a magnetic tile clamping position and an anti-magnetic housing. The upper and lower anti-magnetic housings are snap-fit so that the external side of the whole magnetic tile is wrapped. The external rotor upper shell and the external rotor lower shell are arranged in the housing. The middle rod part of the rotor body stretches out of the middle of the housing. According to the DC ceiling fan motor external rotor, magnetic force of the magnetic tile can be enhanced, production cost can be reduced, and a problem of poor reliability in adhesion of the magnetic tile can also be solved.
Description
Technical field
The utility model relates to a kind of motor outer rotor, particularly relates to a kind of direct current ceiling-fan motor external rotor.
Background technology
Existing ceiling-fan motor external rotor has magnetic shoe to be directly bonded on motor housing or on iron ring, exists adhesive adhesion reliability unstable, has the risk that comes off; Also have motor outer rotor to connect support foot with cast aluminium, install the technique of external rotor upper-lower casing additional, there will be the expensive and high shortcoming of cast aluminium car secondary operations production cost of cast aluminium support foot raw material; Have magnetic shoe to add the external rotor production technology of loading onto plastics connection bracket after iron ring, this technique has complex manufacturing, the deficiency that the yielding stationarity of plastics is poor again.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of direct current ceiling-fan motor external rotor, and it can improve magnetic shoe magnetic force, can reduce production costs again, can solve again the poor problem of magnetic shoe adhesion reliability.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of direct current ceiling-fan motor external rotor, it is characterized in that, it comprises shell, rotor body, magnetic shoe, external rotor upper shell and the external rotor lower house of fixing magnetic shoe, magnetic shoe is placed on the outside of rotor body, external rotor upper shell and external rotor lower house are equipped with magnetic shoe screens and antimagnetic shell, after upper and lower two antimagnetic shells fasten, whole magnetic shoe outside is wrapped up, external rotor upper shell and external rotor lower house are all positioned at shell, the intermediate bar subdivision of rotor body is stretched out from the centre of shell.
Preferably, described external rotor upper shell has the rammed lower bayonet slot of laying magnetic shoe.
Preferably, described external rotor lower house has the rammed upper draw-in groove of laying magnetic shoe.
Preferably, the height of described magnetic shoe screens is 1/10th of magnetic shoe.
Positive progressive effect of the present utility model is: the utility model can improve magnetic shoe magnetic force, can reduce production costs again, can solve again the poor problem of magnetic shoe adhesion reliability.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model direct current ceiling-fan motor external rotor.
Fig. 2 is the structural representation of the utility model external rotor lower house.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As depicted in figs. 1 and 2, the utility model direct current ceiling-fan motor external rotor comprises external rotor upper shell 2 and the external rotor lower house 5 of shell 1, rotor body 3, magnetic shoe 4, fixing magnetic shoe 4, magnetic shoe 4 is placed on the outside of rotor body 3, external rotor upper shell 2 and external rotor lower house 5 are equipped with magnetic shoe screens 6 and antimagnetic shell 7, after upper and lower two antimagnetic shells 7 fasten, whole magnetic shoe 4 outsides are wrapped up, external rotor upper shell 2 and external rotor lower house 5 are all positioned at shell 1, and the intermediate bar subdivision of rotor body 3 is stretched out from the centre of shell 1.
External rotor upper shell 2 has the rammed lower bayonet slot 21 of laying magnetic shoe.External rotor lower house 5 has the rammed upper draw-in groove 51 of laying magnetic shoe.While producing assembling, external rotor upper shell 2 and external rotor lower house 5 can firmly be installed on magnetic shoe between upper draw-in groove and lower bayonet slot.
The height of magnetic shoe screens 6 be magnetic shoe 4 height 1/10th, after external rotor upper shell 2 and external rotor lower house 5 fastens just in time whole magnetic shoe outside parcel.
Because magnetic shoe outside is wrapped up completely, good shielding action is played in magnetic shoe magnetic field, and screens highly arranges rationally, when can fixing magnetic shoe, magnetic field shielding is reduced to minimum, effectively strengthen internal magnetic field, make whole motor outer rotor not only energy-conservation but also rotating speed is faster.
The utility model direct current ceiling-fan motor outer-rotor structure is simple, can strengthen the magnetic force of magnetic shoe, can improve again the high and magnetic shoe of existing motor cast-aluminum production cost, and the problem that adhesion reliability is poor can be used in various direct current ceiling-fan motors.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect to solution of the present utility model further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
