Permagnetic synchronous motor shellTechnical field
The utility model relates to permagnetic synchronous motor, relates to a kind of permagnetic synchronous motor shell or rather.
Background technology
At present, industrial technology progress is very fast, and people also get more and more for the research and development and utilizing of motor.Corresponding power of motor increasing, the heat distributed during work is also increasing, but, motor radiating space is more and more less, namely more and more higher requirement is proposed to the radiating efficiency in motor unit space, if the radiating efficiency of motor is not high, be easy to cause burn-down of electric motor.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of structure simple, the permagnetic synchronous motor shell of good heat dissipation effect.
Technical solution of the present utility model is, a kind of permagnetic synchronous motor shell with following structure is provided, comprise the circular shell for arranging fin, described enclosure bottom and the both sides of end face are equipped with erection column, the left surface of described shell and the both sides of right flank are equipped with installing hole, it is characterized in that: described fin comprises the left surface that horizontal symmetrical is arranged on shell, first groups of fins of the right flank of shell and be vertically symmetricly set on the bottom surface of shell, second groups of fins of the end face of shell, the first described groups of fins shape is identical and evenly arrange, concordant with erection column on the upside of the second described groups of fins, between the second described groups of fins, spacing becomes large by erection column centre position gradually to erection column direction.
After adopting above structure, permagnetic synchronous motor shell of the present utility model, compared with prior art, have the following advantages: by evenly arranging the first groups of fins, effectively expand the left surface of shell, the right flank area of dissipation of shell, and the first groups of fins cambered surface that free end forms and shell concentric, be convenient to Homogeneouslly-radiating, second groups of fins is when ensureing that not affecting erection column installs, abundant extension is concordant with erection column, considerably increase area of dissipation, and structure is simple, between the second described groups of fins, spacing becomes large by erection column centre position gradually to erection column direction, make fin interval longer in the second groups of fins longer, fin interval shorter in second groups of fins is shorter, outer casing top surface and enclosure bottom is made to have comparatively Homogeneouslly-radiating area, greatly improve the radiating efficiency on outer casing top surface and enclosure bottom and dispel the heat evenly, make in unit space, there is high efficiency heat radiation.
Because the described some free ends of the first groups of fins of the present utility model are provided with trade mark platform, by arranging trade mark platform at fin free end, not only do not affect the radiating efficiency of fin and increase area of dissipation, and it is functional that fin is had more.
Improve as one of the present utility model, described installing hole is arranged and corresponding erection column side, by installing hole is arranged and corresponding erection column side, installing hole and erection column and two is made to be one, considerably increase area of dissipation, make fin radiating efficiency higher, improve the radiating efficiency of motor.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to shown in Fig. 1, permagnetic synchronous motor shell 2 of the present utility model, technical solution of the present utility model is, a kind of permagnetic synchronous motor shell 2 with following structure is provided, comprise the circular shell 2 for arranging fin 1, described shell 2 bottom surface and the both sides of end face are equipped with erection column 3, the described left surface of shell 2 and the both sides of right flank are equipped with installing hole 4, it is characterized in that: described fin 1 comprises the left surface that horizontal symmetrical is arranged on shell 2, first groups of fins 11 of the right flank of shell 2 and be vertically symmetricly set on the bottom surface of shell 2, second groups of fins 12 of the end face of shell 2, the first described groups of fins 11 shape is identical and evenly arrange, concordant with erection column 3 on the upside of the second described groups of fins 12, between the second described groups of fins 12, spacing becomes large by erection column 3 centre position gradually to erection column 3 direction, by evenly arranging the first groups of fins 11, effectively expand the left surface of shell 2, the right flank area of dissipation of shell 2, and the first groups of fins 11 cambered surface that free end forms and shell 2 concentric, be convenient to Homogeneouslly-radiating, second groups of fins 12 is when ensureing that not affecting erection column 3 installs, abundant extension is concordant with erection column 3, considerably increase area of dissipation, and structure is simple, between the second described groups of fins 12, spacing becomes large by erection column 3 centre position gradually to erection column 3 direction, make fin 1 interval longer in the second groups of fins 12 longer, fin 1 interval shorter in second groups of fins 12 is shorter, shell 2 end face and shell 2 bottom surface is made to have comparatively Homogeneouslly-radiating area, greatly improve the radiating efficiency on shell 2 end face and shell 2 bottom surface and dispel the heat evenly, make in unit space, there is high efficiency heat radiation.
The described some free ends of the first groups of fins 11 are provided with trade mark platform 5, by arranging trade mark platform 5 at fin 1 free end, not only do not affect the radiating efficiency of fin 1 and increase area of dissipation, and it is functional to make fin 1 have more, described installing hole 4 is arranged and corresponding erection column 3 side, by installing hole 4 being arranged and corresponding erection column 3 side, installing hole 4 and erection column 3 and two is made to be one, considerably increase area of dissipation, make fin 1 radiating efficiency higher, improve the radiating efficiency of motor.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
