Abstract
The invention discloses a stator housing for a fan motor of a car radiator. The stator housing comprises a housing body, wherein a magnetic ring is installed at the external surface of the housing body, the edge rolling gap of the magnetic ring is opened, both the two end parts of the magnetic ring, which are close to the edge rolling gap, are in spot welding with the housing body, positions of the magnetic ring which are symmetrical to the welding spot positions of the end parts are in spot welding on the housing body. Because the magnetic ring has elasticity and the edge rolling gap of the magnetic ring is opened, the processing roundness of the housing is guaranteed, accordingly, a rotor keeps the same air gap with two magnetic shoes, thus not being subjected to the unilateral magnetic pull function during the operation process of the motor, accordingly, the motor can stably operate, the noise pollution is reduced, and the service life of the motor is prolonged.
Description
Technical field
The present invention relates to machine field, be meant that especially a kind of automobile radiators fan electromotor uses stator cage.
Background technology
The automobile radiators fan electromotor that uses is at present used stator cage; Its band fixedly magnetic guiding loop of wing plate is rolled up the circle seam for stinging seam riveted formula; Promptly make magnetic guiding loop be fixed into annular through interference fit, means of spot welds between magnetic guiding loop and the casing then, the shortcoming of so planting seam construction is: the magnetic guiding loop diameter dimension behind the riveted is fixing; Diameter is also fixing after the casing stretch forming; Casing and magnetic guiding loop are matched in clearance, and casing adopts the spot welding mode to connect with magnetic guiding loop, and the spot welding position is the two assembly weldings point that on the magnetic guiding loop face of cylinder, is symmetrically distributed.In casing and the magnetic guiding loop pinpoint welding procedure owing to have the gap between casing and the magnetic guiding loop; So casing can be because of receiving the tractive quilt along radially drawing flat distortion; Cause casing circularity poor, cause and close-fitting magnetic shoe of casing internal diameter and rotor between air gap inhomogeneous, the whole magnetic property of motor is asymmetric; Radially disturbance takes place in the effect of rotor power in the dissymmetrical magnetic field easily, and it is not steady finally to cause motor to rotate.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of automobile radiators fan electromotor to use stator cage, this stator cage has guaranteed that casing adds the circularity in man-hour, makes motor operate steadily, and reduces noise pollution, prolongs motor useful life.
For solving the problems of the technologies described above; Technical scheme of the present invention is: the automobile radiators fan electromotor is used stator cage; Comprise housing, the outer surface of said housing is equipped with magnetic guiding loop, and the volume circle slit of said magnetic guiding loop becomes the opening shape; Said magnetic guiding loop is near the both ends in volume circle slit means of spot welds all and between the housing, and the site that the bond pad locations of said magnetic guiding loop and end is symmetrical is welded on the said housing.
As a kind of preferred scheme, said volume is justified the zigzag that is shaped as in slit.
As a kind of preferred scheme, being shaped as of said volume circle slit is trapezoidal.
After having adopted technique scheme, effect of the present invention is: because the volume of magnetic guiding loop circle slit is the opening shape, so the size of magnetic guiding loop is unfixing; During with housing spot welding; Slight distortion can appear in magnetic guiding loop, and housing can't be out of shape, and guarantees that like this rotor is consistent with size of gaps between two magnetic shoes; Make motor can not receive the unilateral magnetic force effect, thereby motor is operated steadily at the running rotor.Adopt the automobile radiators fan electromotor of this structure; Avoided making rotor that the phenomenon that radially jumps take place when rotating owing to the air gap between rotor and stator magnetic shoe is inhomogeneous; Thereby make the efficient and the rotational stability that have guaranteed machine operation; Both reduce noise pollution, prolonged motor useful life again.

Embodiment
Through specific embodiment automobile radiators fan electromotor of the present invention is done further to describe in detail with stator cage below.
Embodiment 1
Like Fig. 1; Shown in 2, the automobile radiators fan electromotor is used stator cage, comprises housing 1; The outer surface of said housing 1 is equipped with magnetic guiding loop 2; 3 the one-tenths opening shapes in the volume of said magnetic guiding loop 2 circle slit, said magnetic guiding loop 2 is near the both ends in volume circle slit 3 means of spot welds all and between the housing 1, and the symmetrical site in position of the solder joint of said magnetic guiding loop 2 and end is welded on the said housing 1.Roll up the zigzag that is shaped as in circle slit 3 described in the present embodiment.
When stator cage was installed, because the volume of magnetic guiding loop 2 circle slit 3 is the opening shape, so the size of magnetic guiding loop 2 was unfixing; During with housing 1 spot welding; Slight distortion can appear in magnetic guiding loop 2, and housing 1 can't be out of shape, and guarantees that like this rotor is consistent with size of gaps between two magnetic shoes; Make motor can not receive the unilateral magnetic force effect, thereby motor is operated steadily at the running rotor.
In the present embodiment, like Fig. 3, shown in 4, being shaped as of volume circle slit 3 is trapezoidal, and with different among the embodiment 1, other are all identical with embodiment 1.The shape in certain said volume circle slit 3 also can be other shapes beyond embodiment 1 and 2, as long as volume circle slit 3 is the opening shape.
Claims (3)
1. the automobile radiators fan electromotor is used stator cage; Comprise housing; The outer surface of said housing is equipped with magnetic guiding loop; It is characterized in that: the volume of said magnetic guiding loop circle slit becomes the opening shape, and said magnetic guiding loop is near the both ends in volume circle slit means of spot welds all and between the housing, and the site that the bond pad locations of said magnetic guiding loop and end is symmetrical is welded on the said housing.
2. the automobile radiators fan electromotor is used stator cage according to claim 1, it is characterized in that: said volume is justified the zigzag that is shaped as in slit.
3. the automobile radiators fan electromotor is used stator cage according to claim 1, it is characterized in that: being shaped as of said volume circle slit is trapezoidal.
