Description
Technical field
The utility model relates to a kind of brushless single phase direct current machine with the special-shape motor shell.
Background technology
Traditional ceiling-fan motor generally all is to adopt load motor, this electric machine structure complexity, production cost is than higher, volume is relatively big, existing ceiling-fan motor generally all is a circular design, along with ceiling-fan motor trends towards the miniaturization development, in order to reduce the thickness of ceiling-fan motor integral body, motor housing often is made into thinner, can only use thinner screw to connect when lower casing connects on connecting.In order to guarantee bonding strength, often many attachment screws to be set on lower casing on the motor.This design brings many inconvenience for the motor installing/dismounting, is unfavorable for producing.
The utility model content
The purpose of this utility model is in order to overcome weak point of the prior art, to provide a kind of simple in structure, installs, convenient disassembly is quick, the ceiling fan brushless single phase direct current machine of the special-shaped motor casing of well-set band.
In order to achieve the above object, the utility model adopts following scheme:
A kind of brushless single phase direct current machine with the special-shape motor shell, comprise motor shaft, on described motor shaft, be set with stator, outside described stator, be arranged with rotor, described rotor comprises an iron cover, in described iron cover, be evenly equipped with a plurality of magnet, outside described rotor, be respectively equipped with on the annular, lower house, on described, the lower house outside is evenly equipped with respectively on a plurality of the increasing, the epitaxy part of lower house local thickness, on described epitaxy part, be provided with connecting hole, on described, lower house is arranged on the described rotor by screw, described rotor and last, lower house respectively by Bearing Installation on described motor shaft.
Aforesaid a kind of brushless single phase direct current machine with the special-shape motor shell is characterized in that described epitaxy part is the arc epitaxy part.
Aforesaid a kind of brushless single phase direct current machine with the special-shape motor shell is characterized in that being respectively equipped with a plurality of louvres on described upper and lower casing.
Aforesaid a kind of brushless single phase direct current machine with the special-shape motor shell, it is characterized in that described louvre is the semicircle louvre that caves inward on the upper and lower casing and form, described semicircle louvre is identical with the direction of motor rotation at the opening of upper and lower casing inside.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model is evenly equipped with a plurality of epitaxy parts that increase upper and lower casing local thickness respectively in the upper and lower casing outside, on described epitaxy part, be provided with connecting hole, described upper and lower casing shell just can be fixedly connected by the relatively big screw of minority, install, convenient disassembly is quick, sound construction.
