Abstract
The invention relates to a stator iron core for a motor. Two or more groups of stator iron core arc segments are spliced together so as to form the stator iron core; the number of the groups of the stator iron core arc segments is corresponding to the number of the phases of the motor; wire incoming and outgoing positions of the phases of the motor are located between the stator iron core arc segments; the stator iron core arc segment includes rectangle-shaped stamped sheets and arc keys; the yoke of each rectangle-shaped stamped sheet is provided with one or more dovetail grooves; the rectangle-shaped stamped sheets are laminated so as to form the stator iron core arc segment; the arc keys are shaped to match the dovetail grooves; and screw threaded holes connected with the base of the motor are formed at the outer circumferential direction of the arc key. According to the stator iron core, the rectangle-shaped stamped sheets are laminated circumferentially so as to from the stator iron core arc segments; and the stamped sheets can be made of high-permeability silicon steel sheets, and the output of the motor can be increased. The invention also relates to a motor comprising the stator iron core.
Description
Technical field
The present invention relates to field of motor manufacturing, particularly relates to a kind of motor stator core and motor.
Background technology
At present, the conventional mover direction of motion is the special Miniature tube type motor of rectilinear motion, its stator core is magnetic conductor material steel, stator slot shape is that monoblock steel are by machining, stator slot shape is arranged in back or centre position, its electromagnetism air gap is comparatively large on the one hand for the shortcoming of this stator core construction, and electric efficiency is low; On the other hand, its iron core is that magnetic conductor material steel overall processing forms, and its magnetic conductivity is well below the molded iron core of silicon steel sheet stack, and leakage field is comparatively large, and iron core vortex loss is comparatively large, and operating efficiency is very low, is only suitable for low-power machine.
Summary of the invention
The object of the invention is to overcome above defect, provide a kind of high efficiency, loss low, high-power, and the wide motor stator core of the scope of application and motor.
Technical scheme of the present invention is: a kind of motor stator core, described stator core is spliced by two groups or more stator core segmental arc, group number and the number of motor phases of described stator core segmental arc match, the line position of number of motor phases is between stator core segmental arc and stator core segmental arc, described stator core segmental arc comprises rectangle punching, arc key, the yoke portion of described rectangle punching is provided with one or more dovetail groove, described stator core segmental arc is overrided to form by rectangle punching, the described shape of arc key and the mating shapes of dovetail groove, the screwed hole be connected with electric machine stand is provided with at the outer circular direction of arc key.
Preferably, formed by bonding between the rectangle punching of same stator core segmental arc and adjacent rectangle punching, the axial Stripping cohesive force > 15N/mm of described bonded adhesives
2.
In order to stator core segmental arc and arc key are completely fixed integrally, the both sides of described stator core segmental arc and arc key contacts weld together.
A kind of motor, it comprises stator core, and described stator core is stator core described above.
Advantageous Effects of the present invention is: because iron core adopts rectangle punching circumference to laminate shaping, Material quality of lamination can adopt the silicon steel sheet of high permeability, bonding with high strength bonding glue material between rectangle punching with rectangle punching, ensure that iron core globality and lamination insulation, avoid the conducting of core stamping face, electromagnetism air gap is less, motor is exerted oneself increase, the V-type groove that stator core segmental arc and stator core segmental arc are formed is convenient to the connection of the lead-out wire of motor, effectively expand the scope of application of stator core, various high-power tube type linear electric motors can be applied, particularly iron core yoke part dovetail groove installation arc key both sides and stator core segmental arc are welded into entirety, greatly improve the bulk strength of iron core.
