Description

A kind of brushless single phase direct current machine

Technical field

The utility model relates to a kind of brushless single phase direct current machine.

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, its epitrochanterian lasso generally all is directly to be stretched by upper casing or lower casing to make, such housing designs complexity, and tend to cause the volume of upper and lower shell to increase; Also there is lasso to make separately at present, fixedlys connected by the mode of welding with upper casing or lower casing then.Such motor complex manufacturing, the installing/dismounting trouble.

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 brushless single phase direct current machine that sound construction, volume compare less.

In order to achieve the above object, the utility model adopts following scheme:

A kind of brushless single phase direct current machine, comprise motor shaft, on described motor shaft, be set with stator, outside described stator, be arranged with rotor, outside described rotor, be respectively equipped with on the motor, lower house, on described, lower house by screw on rotor, on the motor, lower house is installed on the described motor shaft by two bearings, it is characterized in that: described rotor comprises an iron cover, in described iron cover, be evenly equipped with a plurality of magnet, the iron cover concaves and forms a groove between two adjacent magnet, on described, be respectively equipped with a plurality of fixture blocks on the lower house, described fixture block is fastened in the described groove, and described screw is arranged in the described groove.

Aforesaid a kind of brushless single phase direct current machine is characterized in that described bearing is separately positioned on the described motor upper and lower casing and is set on the motor shaft.

Aforesaid a kind of brushless single phase direct current machine is characterized in that described fixture block is four.

Aforesaid a kind of brushless single phase direct current machine is characterized in that being respectively equipped with a plurality of louvres on described motor upper and lower casing.

Aforesaid a kind of brushless single phase direct current machine is characterized in that described louvre is the semicircle louvre that upper and lower casing caves inward and forms, and 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:

In the utility model between two adjacent magnet the iron cover concave and form a groove, the motor upper and lower shell connects by screw, and described screw is arranged in the groove, firmly be connected thereby make between iron cover and the upper and lower shell, the fixture block that can be connected in the described groove is set on upper and lower shell, further fixedly connected between making upper and lower shell and iron overlapping, safe and reliable.Installation, convenient disassembly, simple to operate, and the volume of motor is reduced.
