Abstract
The invention discloses an efficient miniature permanent-magnet direct-current motor. The efficient miniature permanent-magnet direct-current motor comprises a casing, a front end cap, a rear end cap, a rotor and a stator formed by two magnetic steel sheets, wherein the front end cap and the rear end cap are respectively mounted at two ends of the casing which is in a drum structure, and the two magnetic steel sheets are respectively mounted on inner walls of two circular arc end faces of the casing. The efficient miniature permanent-magnet direct-current motor is simple in structure and easy to realize. Since the casing is in the drum structure and the magnetic steel sheets are mounted on the inner walls of the two circular arc end faces of the casing, material and space are saved. The width of the motor is less than 40mm, the length thereof is less than 46mm, the rated output power thereof can reach about 200W which is equivalently 60% higher than a motor in an equivalent space, and accordingly, energy is greatly saved.
Description
Technical field
The present invention relates to a kind of permanent magnet direct current motor, relate in particular to a kind of micro high efficiency permanent magnet direct current motor.
Background technology
At present, with domestic Medium voltage switch or circuit breaker history, begin from initial oil switch, to low-oil-content circuit-breaker, to air switch, finally vacuum switch cabinet arrive solid insulation switch etc. again, the developing trend miniaturization of switch, and all insulation, hermetically sealed, intelligent direction develops.It is more little good more that this just requires with the supporting motor of switch cubicle, but to concrete use and installation environment, owing to receive the restriction of many conditions, design that to satisfy volume little, high-power micromotor not a duck soup.In existing technology, the width of motor is less than 40mm, and under the situation of length less than 46mm, the rated output power maximum of motor can only reach 120W, can't satisfy the requirement of some particular application.
Summary of the invention
The objective of the invention is to provides a kind of micro high efficiency permanent magnet direct current motor to the problems referred to above, is reaching under the situation of required power output the problem that the motor volume is bigger to solve original motor.
The objective of the invention is to realize through following technical scheme:
A kind of micro high efficiency permanent magnet direct current motor; Comprise casing, front end housing, rear end cap, rotor and the stator of forming by two magnet steel; Said front end housing, rear end cap are installed on the two ends of said casing respectively; Said casing is a drum organization, and described two magnet steel are installed in respectively on the inwall of two circular arc end faces of casing of drum shape.
Further, described two magnet steel all are bonded on the circular arc inwall of casing through glue.
Further, described two magnet steel are ferrite magnetic steel.
Further; Have bolt hole a on the said front end housing; The bolt hole position of corresponding front end housing has bolt hole b on the said rear end cap, and connecting bolt passes bolt hole a, bolt hole b front end housing, rear end cap are anchored on the two ends of casing, and connecting bolt is positioned at the casing outside.
Beneficial effect of the present invention is that said micro high efficiency permanent magnet direct current motor is simple in structure, is easy to realize; It adopts the casing of drum organization, and magnet steel is installed on the inwall of circular arc end face of casing of drum shape, has practiced thrift material; Saved the space, the width of its motor is less than 40mm, and length is less than 46mm; Rated output power can reach about 200W, is equivalent in equal space, power of electric motor improved 60%, has saved the energy greatly.

Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please referring to figs. 1 through shown in 5; In present embodiment; A kind of micro high efficiency permanent magnet direct current motor comprises that casing 5, front end housing 2, rear end cap 1, rotor 3 reach the stator of being made up of two magnet steel 4, have bolt hole a on the said front end housing 2; The bolt hole position of corresponding front end housing 2 has bolt hole b on the said rear end cap 1; Connecting bolt 6 passes bolt hole a, bolt hole b front end housing 2, rear end cap 1 is anchored on the two ends of casing 5, and said connecting bolt 6 is positioned at the outside of casing 5, and said casing 5 is a drum organization; Described two magnet steel 4 are bonded on the inwall of two circular arc end faces of casing 5 of drum shape through glue respectively, and described two magnet steel 4 are ferrite magnetic steel.
The present invention is simple in structure, is easy to realize that it adopts the casing 5 of drum organization; Magnet steel 4 is installed on the inwall of circular arc end face of casing 5 of drum shape, has practiced thrift material, has saved the space; The width of its motor is less than 40mm, and length is less than 46mm, and rated output power can reach about 200W; Be equivalent in equal space, power of electric motor improved 60%, saved the energy greatly.
Above embodiment has just set forth basic principle of the present invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
