Abstract
The utility model provides a motor stator, which belongs to the technical field of motors, and solves the problem of non-uniform magnetic density distribution on the existing motor stator. The motor stator is of a barrel-shaped structure formed by superposing a plurality of same annular stator sheets along an axial direction, wherein four uniformly-distributed planes are formed on the outer edge of each stator sheet; a bayonet sunken from outside to inside is formed in the middle of each plane; the two sides of the bayonet are slantwise formed so that the bayonet is gradually enlarged along the circle centre direction of the stator sheet; location surfaces are symmetrically arranged at the both ends of the two opposite planes respectively; the location surfaces are level with the bottom surface of the bayonet aforementioned; and arc surfaces are formed between the location surfaces and the planes. The stator sheets of the motor stator provided by the utility model are uniform in magnetic density distribution, so that the generation of the sawtooth waves of a power generator can be reduced, and the fluctuation amplitude of the current output by the power generator is low, thus ensuring the normal running of electric equipment.

Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed motor stator, and simple, the reliable operation of this stator structure helps stable, the electric current efficiently of generator output.
The purpose of this utility model can realize by following technical proposal: a kind of motor stator, described stator is formed by stacking tubular structure vertically by several identical stator pieces in the form of a ring, it is characterized in that, have four equally distributed planes on the outward flange of described stator piece, the in-plane on each plane is provided with the recessed bayonet socket of ecto-entad, this bayonet socket dual-side is obliquely installed this bayonet socket is increased gradually along the center of circle direction of stator piece, two ends two opposite planar are arranged with locating surface respectively, described locating surface flushes with above-mentioned bayonet socket bottom surface, is arc surface between described locating surface and the plane.
This stator adopts silicon steel material to make, and at first silicon steel sheet is carried out punching press by specification, the shape of stator piece, and is then that the stator piece of rushing out is together overlapped, by the method for riveted joint, makes it be processed into stator again.This stator piece outward flange integral body is a circle, this circle mainly is to constitute by several sections even and concentric circular arcs, even and concentric circular arc makes the magnetic density intensity of stator piece on each orientation all identical, magnetic density is evenly distributed, reduced the generation of generator sawtooth waveforms, make the current fluctuation amplitude of generator output less simultaneously, guarantee the normal operation of power consumption equipment, and help prolonging the useful life of power consumption equipment.Have bayonet socket on this stator piece, this bayonet socket can play to save on the one hand produces raw-material purpose, thereby saves production cost; On the other hand, pilot pin can also be set in the bayonet socket word slice of deciding that is stacked is prolonged it and circumferentially and radially fixes, help improving stator core body grooved regularity.
In above-mentioned motor stator, the distance between described locating surface and the plane is two millimeters.
In above-mentioned motor stator, the inside edge of described stator piece is evenly equipped with winding body, is provided with the Access Division that is connected as a single entity with winding body in the inner of above-mentioned winding body, and the inner edge of described Access Division is an arc limit.
In above-mentioned motor stator, the inner edge of described Access Division forms a circle inner ring, and the diameter of this circle inner ring is 72mm, and the stator piece race diameter is 135mm.
In above-mentioned motor stator, arc transition between described winding body and the stator piece.
In above-mentioned motor stator, describedly on stator piece, circumferentially be provided with eight riveted holes.
Compared with prior art, this motor stator has the following advantages:
1, the stator piece outward flange integral body in this stator is set to circle, the stator piece magnetic density is evenly distributed, and can reduce the generation of generator sawtooth waveforms, makes the current fluctuation amplitude of generator output less, guarantee the normal operation of power consumption equipment, and help prolonging the useful life of power consumption equipment.
2, have several equally distributed bayonet sockets on the outward flange of stator piece, bayonet socket can be saved on the one hand the production raw material, and bayonet socket is provided with pilot pin and can also improves stator core body grooved regularity in addition.
3, the utility model reliable operation, simple in structure, advantage such as production cost is low.
