Abstract
The utility model discloses a mounting structure for a permanent magnet motor stator used for quickly mounting and fixing the permanent magnet, the brush retainer and the brush connecting wires of a motor stator. The mounting structure comprises an enclosure, a plurality of permanent magnets, a plurality of auxiliary poles, a brush retainer, and brush connecting wires. The auxiliary poles are arranged on the internal circumferential face of the enclosure alternately in the longitudinal direction by means of one-piece moulding. The permanent magnets are inserted in magnet grooves formed by two adjacent auxiliary poles and the enclosure. A protrudent stop collar used for axially positioning the permanent magnets is arranged on the internal circumferential face of the near back end of the enclosure. At least one protrudent punch point is arranged on the surface of each auxiliary pole on the near front end of the enclosure, which is close to the two side walls of the magnet grooves. A plurality of lug bosses are arranged at intervals on the internal circumferential face of the front end of the enclosure. The brush retainer is a loop and is arranged on the front end of the enclosure. A plurality of notch grooves are arranged on the external circumferential face of the brush retainer, which correspond to the lug bosses on the enclosure. A plurality of clamping trunkings used for fixing the brush connecting wires are arranged at intervals on the annular face of the brush retainer.
Description
Technical field
The utility model relates to a kind of magneto, is specifically related to a kind of mounting structure of permanent magnet motor stator.
Background technology
At present, the installation of the permanent magnet on the magneto generally adopts glue to be bonded on the casing, installs so that spring retainer location is auxiliary again, can affect to the reliability of motor, the fault that permanent magnet or retainer come off can occur, influence electrical machinery life.The brush connecting line connects by flexible cord or is fixed on the brush carrier, can cause brush connecting line and casing short circuit to burn motor, and the method that adopts the brush connecting line to be fixed on the brush carrier also is unfavorable for the maintenance and the replacing of brush, so has increased use cost.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of mounting structure of permanent magnet motor stator to be provided, and it can make the Fast Installation of permanent magnet, brush retainer and brush connecting line of motor stator and fixing.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of mounting structure of permanent magnet motor stator, comprise casing, plurality of permanent magnets, some auxilliary utmost points, brush retainer and brush connecting line, wherein,
The described auxilliary utmost point with the integrated mode longitudinal separation of casing be located on the inner surface of casing;
Described permanent magnet is planted in the magnet groove that is made of the two adjacent auxilliary utmost points and casing;
The prominent spacing ring that is used for the permanent magnet axial location of establishing on the inner peripheral surface of the nearly rearward end of described casing;
Extremely be equipped with one at least towards point on the surface in that each of the end nearby of described casing is auxilliary, and should dash the two side of point near described magnet groove;
Be interval with some projections on the inner peripheral surface of described casing leading section;
Described brush retainer is an annulus and the leading section that is located at casing, and the projection on its outer peripheral face on the corresponding casing is provided with some gap slots, and the compartment of terrain is provided with some cable clamping interfaces that are used for fixing the brush connecting line on its anchor ring.
The mounting structure of above-mentioned permanent magnet motor stator, wherein, the pocket side wall of described magnet groove is inwardly dwindled and is had angle with its two side and is α.
Owing to adopted the technical scheme of the mounting structure of permanent magnet motor stator of the present utility model, realized the Fast Installation of the permanent magnet in the permanent magnet motor stator, brush retainer and brush connecting line and fixing, made things convenient for the maintenance of motor.

Embodiment
See also Fig. 1 to Fig. 5, the mounting structure of permanent magnet motor stator of the present utility model, comprise casing 1, plurality of permanent magnets 2, some auxilliary utmost points 3, brush retainer 4 and brush connecting line 5, wherein, the auxilliary utmost point 3 with casing 1 integrated mode longitudinal separation be located on the inner peripheral surface of casing 1;
Prominently on the inner peripheral surface of the nearly rearward end of casing 1 establish a spacing ring 10, be used for axial location an end of permanent magnet 2;
On each the auxilliary utmost point 3 surface of the end nearby of casing 1, be equipped with one at least and dash point 30, and should dash the two sides of point 30 near magnet grooves 20; After permanent magnet 2 is in place, this is dashed the axial location of point 30 punching presses realization to permanent magnet 2 other ends by stamping tool;
Be interval with some projections 11 on the inner peripheral surface of casing 1 leading section;
The compartment of terrain is provided with some cable clamping interfaces 42 on the anchor ring of brush retainer 4, is used for fixing brush connecting line 5; Brush connecting line 5 snaps in the brush connecting line draw-in groove 42, thus the Fast Installation of realization permanent magnet 2, brush retainer 5 and casing 1 and fixing.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
