Abstract
The utility model relates to a housing for motors, which belongs to motor components; wherein the housing comprises a housing body the outer surface of which is provided with a plurality of circular cooling plates evenly distributed along the motor axis. Since the circular cooling plates are evenly distributed on the outer surface of the housing along the motor axis, the circular plane and the useful flux of the stator are in the same plane, thus increasing the section area of useful flux, reducing the magnetic loss, and increasing the motor efficiency; meanwhile the dissipation area of the motor surface is expanded and the heat productivity of the housing body is reduced caused by the reduction of flux density.
Description
Technical field
The utility model relates to a kind of motor component, relates in particular to a kind of motor case.
Background technology
Magneto because of have the life-span long, noise is low, technology is simple and characteristics such as capacity usage ratio height are widely used in every field.Existing magneto is generally installed permanent magnetic steel as electrode at the circumference antimere of chassis cavity, and utilizes loop that the casing fuselage passes through as magnetic field to save permeability magnetic material.Closed magneto generally adopts rotor to attach blade, dispels the heat through casing by the inner air circulation.Approaching of the wall thickness design of casing, though help the air heat transfer cooling of motor, because casing is the main flux circuit of stator, thin casing wall thickness must make magnetic flux density increase, thereby increased the caloric value of casing ontology, and increased stator loop magnetic resistance, reduced electric efficiency.Thicker casing then is unfavorable for the motor surface radiating, and has increased product weight and cost.
Summary of the invention
The utility model is in view of the above deficiency of prior art, provides a kind of and not only utilized the motor surface radiating, but also increases the high efficiency magneto casing of motor stator magnetic circuit sectional area.
Goal of the invention of the present utility model realizes by following scheme: a kind of motor case, comprise fuselage, the outer surface of described fuselage be provided with some along motor shaft to equally distributed ring-like fin.
Magneto casing appearance of the prior art does not generally have fin or has only along the radially-arranged vertical bar type of motor fin.The useful flux of motor stator be along perpendicular to motor shaft to the sagittal plane in flow, so, can not increase casing magnetic flux net sectional area even the motor case outer surface has above-mentioned said vertical bar type fin.Because the utility model is to even distribution ring-like fin to be set along motor shaft at casing outer surface, the useful flux of this ring-like plane and stator is in a plane, so increased the sectional area of useful flux, reduced magnetic flux density and magnetic loss, improved electric efficiency; The area of dissipation and because the decline of the caloric value of casing fuselage that the magnetic flux density reduction brings own on motor surface have been expanded simultaneously.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model cutaway view.
Embodiment
As shown in Figure 1, the utility model is to even distribution ring-like fin 2 to be set along motor shaft at casing fuselage 1 outer surface, and ring-like fin 2 is cast into one with fuselage 1.For increasing the intensity of ring-like fin 2, two or four reinforcements 3 that connect the symmetrical distribution of also vertical each fin are set on the casing surface.
Claims (2)
1, a kind of motor case comprises fuselage, the outer surface that it is characterized in that described fuselage be provided with some along motor shaft to equally distributed ring-like fin.
2, motor case according to claim 1 is characterized in that being provided with between described each ring-like fin the reinforcement of some symmetrical distributions.
