Abstract
The utility model relates to a stator core for disk motors, which consists of an installation foot and an iron core; wherein, the iron core is made of strip electric steel which is cut, punched and winded into a disk, and the upper part of the disk is provided with aligned slots; the shape of all slots are complete identical and the installation foot is welded on the iron core. Compared with the prior art, the utility model occupies small area with simple equipments.
Description
Technical field
The utility model relates to motor stator core, is specifically related to a kind of disk type motor stator core and preparation method thereof.
Background technology
The stator core of conventional motors is to sweep away circular punching on electric steel plate, punching is formed by stacking again, and this iron core has following deficiency:
1, stock utilization is low.Because electric steel plate dispatches from the factory and is generally the cylindrical steel roll form, add and earlier coil of strip is cut into the rectangle steel plate man-hour, on sheet steel, go out circular punching then, this mode of production must cause stock utilization low.With the electric steel plate upper punch external diameter of 200mm * 640mm is that 100 punching is example (going out the rotor punching simultaneously), and the utilance of material only is about 65%;
2, the motor axial length is longer, is unfavorable for saving the space, and the motor complicated integral structure, is unfavorable for maintaining;
3, be unfavorable for heat radiation, be difficult to improve power density.
Summary of the invention
The purpose of this utility model is exactly to provide disk type motor stator core that a kind of equipment is simple, area occupied is little and preparation method thereof for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of disk type motor stator core, it is characterized in that, this motor stator core is formed by footing and iron core are installed, described iron core for band shape electrical sheet through cutting, jet-bedding, the disk that is wound into, the top of this disk is the groove of alignment, the flute profile of all grooves is in full accord, and the groove center line points to circle disk center, and described installation footing is welded on the iron core.
Described flute profile comprises straight trough, skewed slot.
Compared with prior art, the utlity model has following advantage:
1, the profile of disc type electric machine stator is in the form of annular discs, and corresponding motor is also in the form of annular discs, and such motor has the short characteristics of axial length, and conditional occasion can be given full play to its effect in a lot of spaces.And the overall structure of motor is very simple, is beneficial to maintaining;
2, the winding of disc type stator is embedded in the surface of iron core, is open distribution, and area of dissipation is very big, compares with the conventional motors with power, and this motor can make volume-diminished 40% under same temperature condition.
Description of drawings
Fig. 1 is the utility model product structure schematic diagram;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the structural representation of the utility model slotting winding machine.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1～2, the utility model product disk type motor stator core structure is very simple, forms by footing 1 and iron core 2 are installed.Iron core 2 is processed on the slotting winding machine tool of special use by band shape electrical sheet, the narrow steel strip jet-bedding after it will be cut out, is wound into disk, and the top of this disk is the groove of alignment, and the flute profile of all grooves is in full accord, and the groove center line points to circle disk center.Iron core processes back leveling on the special tooling platform, welding footing, finishes the production of product.
As shown in Figure 3, be used to implement to produce the special-purpose slotting winding machine tool of the utility model method for product, comprise take-off reel 3, feeding table 4, stamping die 5, jig 6, welding machine 7, iron core dish 8, closed reel 9, fuselage 10, operation panel 11, cylinder 12, before described take-off reel 3 is arranged on feeding table 4, after described stamping die 5 is arranged on feeding table 4, be provided with closed reel 9 behind the stamping die 5, the electrical sheet winding that punching press is good is wound into iron core dish 8 on closed reel 9, iron core dish 8 tops are provided with welding machine 7, the below is provided with jig 6, the back is provided with fuselage 10, this fuselage 10 connects cylinder 12, and is provided with operation panel 11 between fuselage 10 and cylinder 12.
The maximum difficult point of this product is punching out and the winding shaping with the shape electrical sheet.This programme adopts the slotting winding machine tool that aims at this sections core design, the electrical sheet winding of being processed into certain width is installed on the take-off reel 3, take-off reel 3 is regularly sent the electrical sheet winding to feeding table 4, go out flute profile through the electrical sheet winding behind the feeding table through stamping die 5, the electrical sheet winding is reeled on closed reel 9 after having dashed flute profile, be wound into iron core dish 8, the alignment of flute profile relies on jig 6 to guarantee on the iron core dish 8, jig 6 provides simultaneously with iron core dish 8 radiuses and has increased the power that fuselage 10 is moved down along guide rail, cylinder 12 is used for the gravity of balance fuselage 10, welding machine 7 is in the head part that goes out of the fixing steel band of beginning to reel and reel when finishing, guarantee that iron core dish 8 is indeformable when closed reel 9 unloads, operation panel 11 is the control board of operation slotting winding machine tool.
The disc type electric machine stator outer diameter of being produced is 600mm, and internal diameter is 450mm, and width is 60mm, and flute profile is a straight trough.Used former coil of strip is the coil of strip of the wide 580mm of Baosteel production, at first this coil of strip is cut into the little coil of strip of 60mm * 9+40mm, on slotting winding machine tool, be processed into the iron core dish with the little coil of strip of cutting out again, as calculated, the utilization rate of raw materials of this product has reached 90%, in today that the electrical sheet prices of raw and semifnished materials sharp rise, this Products Development has been saved great amount of cost.
Claims (2)
1. disk type motor stator core, it is characterized in that, this motor stator core is formed by footing and iron core are installed, described iron core for band shape electrical sheet through cutting, jet-bedding, the disk that is wound into, the top of this disk is the groove of alignment, the flute profile of all grooves is in full accord, and the groove center line points to circle disk center, and described installation footing is welded on mandrel lower.
2. a kind of disk type motor stator core according to claim 1 is characterized in that described flute profile comprises straight trough, skewed slot.
