Abstract
The invention relates to a special-shaped slotted disc type motor stator core. Wire grooves are uniformly distributed on the core in the radial direction; and the special-shaped slotted disc type motor stator core is characterized in that: the grooves on the outer circle of the core are wide and shallow and the grooves on the inner circle of the core are narrow and deep, and an equal-area lofting special-shaped groove structure is formed, so that the ratio of the tooth width to the yoke thickness on the outer circle is close or equal to that on the inner circle and the tooth parts and the yoke parts have basically the same magnetic flux density in the magnetic circuit from the outer circle to the inner circle of the core. The special-shaped slotted disc type motor stator core has novel design and improves the structure of the magnetic circuit, solves the problem of local magnetic circuit saturation of the slotted disc motor stator core, effectively reduces temperature rise and improves the motor efficiency through improvement of the wire grooves.
Description
Technical field:
The invention belongs to technical field of motors, particularly a kind of improvement of special-shaped slotted disc type motor stator core.
Background technology:
In the tradition disc type motor technology, groove, tooth on its stator core plane are radial distribution.During machine operation, the epitrochanterian magnetic line of force forms magnetic loop by air gap, stator teeth, stator yoke portion, the stator teeth of consecutive roots, air gap, rotor, and the lead and the magnetic line of force in the loop in the groove produce electromagnetic induction mutually.
Tradition disc type stator core: in order to make the convenience of stator, the grooved of disc type stator core cylindrical and interior circle is identical, this just causes the facewidth at stator cylindrical place excessive, the facewidth of stator inner circle is too small, and the yoke portion of stator cylindrical and inner circle equates, thereby caused the ratio of the facewidth of cylindrical and inner circle and yoke portion thickness unequal, promptly on excircle, magnetic circuit sectional area ratio yoke portion of tooth portion magnetic circuit sectional area is big; On inner periphery, magnetic circuit sectional area ratio yoke portion of tooth portion magnetic circuit sectional area is little.Magnetic flux density is bigger than tooth portion in excircle yoke portion, inner periphery tooth portion magnetic flux density is bigger than yoke portion, and on different circumference, tooth, yoke flux density differ greatly, the magnetic circuit height of excircle yoke portion and inner periphery tooth portion is saturated, causes stator temperature height, waste of material, defective that electric efficiency is low.Particularly more serious at iron core cylindrical and interior diameter of a circle than surpassing at 1.7: 1 o'clock.
Summary of the invention:
The objective of the invention is to invent a kind of flute profile is homalographic setting-out abnormity groove, improves the saturated special-shaped slotted disc type motor stator core of iron core cylindrical yoke portion and internal-round gear portion magnetic circuit.
Technical solution of the present invention is achieved in that a kind of special-shaped slotted disc type motor stator core, and iron core is evenly equipped with radial wire casing, it is characterized in that iron core cylindrical place wire casing is wide and shallow, the inner circle wire casing is narrow and dark, and becomes homalographic setting-out abnormity groove structure.Make the facewidth degree and yoke portion thickness ratio at cylindrical place, be close with yoke portion thickness ratio with the facewidth degree of inner circle or be tending towards equating, reduce or avoid the saturated of local magnetic circuit.
The tooth portion width and the yoke portion thickness ratio at the tooth portion width at described outer nose circle place and yoke portion thickness ratio and interior nose circle place are more or less the same in 20%.
Described radial wire casing becomes radial equipartition on iron core.
Described radiation wire casing is distributed on the iron core with radially having angle.
The present invention has novel, and the improvement by wire casing improves magnetic structure, reduces or avoids the saturated defective of magnetic circuit, effectively reduces temperature rise, improves electric efficiency.

Wherein
The 1-iron core 2-wire casing 3-tooth 4-of portion yoke portion
Embodiment:
With reference to Fig. 1, Fig. 2, Fig. 5 and Fig. 6,2 one-tenth homalographic setting-out abnormity of the wire casing of disk type motor stator core 1 groove structure also is that its sectional area on different circumference equates, copper factor equates behind the embedding coil.2 one-tenth radial radiation shapes of wire casing are distributed on the iron core 1, and wherein the wire casing 2 at iron core cylindrical place is wide and shallow, and its tooth portion 3 width of conventional art diminish relatively, and yoke portion 4 thickness thicken, and both diminish by ratio; The wire casing 2 of inner circle is narrow and dark, and its tooth portion 3 width of conventional art become big relatively, the 4 thickness attenuation of yoke portion, and it is big that both ratios become; Make tooth portion width and the yoke portion thickness ratio at iron core cylindrical and interior circle two extreme places, convergence or equal gradually.Make iron core from cylindrical to the magnetic circuit of interior circle, the magnetic flux density of tooth portion, yoke portion is basic identical everywhere, avoids occurring local magnetic circuit saturated phenomenon.Therefore, the iron core cylindrical can surpass more than 2: 1 with interior diameter of a circle ratio, and the tooth portion width at the tooth portion width at outer nose circle place and yoke portion thickness ratio and interior nose circle place and yoke portion thickness ratio differ, can be controlled in and be not more than within 20% scope, especially at cylindrical and interior diameter of a circle than little iron core, the tooth portion width at two ends places can accomplish to equate with yoke portion thickness ratio, also be that ratio differs is zero.
Fig. 1 and Fig. 2 are 12 slotted disc type stator cores, and Fig. 5 and Fig. 6 are 36 slotted disc type stator cores.
Above groove number is that the requirement to rotating speed, number of pole-pairs designs according to motor, also can be various groove numbers such as 24,48.
With reference to Fig. 3 and Fig. 4, be 18 slotted disc type stator cores, radial wire casing 2 with radially become-angle is distributed on the iron core 1, can improve the waveform of motor output like this.
