Abstract
The utility model relates to the technical field of motor equipment, in particular to a self-fastening rivet core, which comprises rotor magnetic steel, a rotor core, a stator core and a stator winding, and also comprises a rivet, wherein the rivet is positioned at the central positions of a stator tooth part and an excircle, the rivet is square or circular, furthermore, the rivet is square, and the size of the rivet is 1.2mm and 2.5 mm; the utility model discloses a motor magnetic line of force is sent out by rotor magnet steel N utmost point, through passing rotor and stator core, gets back to rotor magnet steel S utmost point again and forms closed return circuit. The riveting points on the tooth parts of the stator core can block the trend of the magnetic lines of force of the motor, the magnetic lines of force can avoid the riveting points of the motor, and thus the jam of the magnetic circuit of the motor can be caused, and the magnetic circuit of the motor is saturated.
Description
Technical Field
The utility model belongs to the technical field of electrical equipment technique and specifically relates to a from buckleing rivet iron core.
Background
The motor iron core is formed by laminating silicon steel sheets, and the traditional motor iron core adopts a rivet, a self-fastening rivet, welding and other modes to laminate and fix an iron core structure. In order to ensure the laminating strength of the iron core, the rivet and the self-clinching rivet are arranged at the center positions of the tooth part and the yoke part of the iron core. The magnetic circuit of motor flows to the stator yoke circuit through stator tooth portion, because the rivet adopts non-magnetic conductive material and detains the rivet certainly and destroy magnetic structure, so adopt the rivet, detain the rivet certainly and can influence the motor magnetic circuit, seriously lead to motor magnetic circuit serious saturation, the motor core loss increases and leads to motor efficiency to reduce, and position and the shape of detaining the rivet certainly influence the motor magnetic circuit very much.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model discloses a from detaining rivet core carries out the simulation contrast to automatic rivet position and shape, size, confirms final rivet shape, size and position, when guaranteeing intensity, reduces the influence to the motor performance as far as possible.
The utility model discloses a specific technical scheme as follows:
the utility model provides a from detaining rivet iron core, includes rotor magnet steel, rotor core, stator core and stator winding, still includes the rivet, and the rivet position is in both central point of stator tooth central point and excircle central point.
The utility model discloses a further improvement, the rivet shape is square or circular, and further, the rivet is square, and the size of rivet is 1.2mm 2.5 mm.
The utility model has the advantages that: the utility model discloses a motor magnetic line of force is sent out by rotor magnet steel N utmost point, through passing rotor and stator core, gets back to rotor magnet steel S utmost point again and forms closed return circuit. The riveting points on the tooth parts of the stator core can block the trend of the magnetic lines of force of the motor, and the magnetic lines of force can avoid the riveting points of the motor, so that the jam of the magnetic circuit of the motor and the saturation of the magnetic circuit of the motor can not be caused.
Drawings
Fig. 1 is a schematic structural view of the square rivet of the present invention.
Fig. 2 is a schematic structural view of the rivet in the present invention, which is circular.
In the figure, 1-rotor magnetic steel, 2-stator iron core, 3-rivet, 4-stator winding and 5-rotor iron core.
Detailed Description
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and embodiments, which are only used for explaining the present invention and are not limited to the protection scope of the present invention.
Example (b): as shown in fig. 1 and 2, a self-clinching rivet core comprises rotor magnetic steel 1, a rotor core 5, a stator core 2, a stator winding 4 and a rivet 3, wherein a distance h2 between the rivet 3 and the center of a stator tooth part is equal to a distance h1 between the rivet 3 and the center of an excircle.
In the present embodiment, the rivet 3 is square or round in shape, and further, the rivet is square, and the size of the rivet is 1.2mm by 2.5 mm.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
