Abstract

The utility model relates to a stator coil which is a coil formed by an enameled wire which is coiled on a stator seat of a magnetic pole. A plurality of enameled wires are simultaneously coiled to form the stator coil. One end of each of the coils is connected. One end of each of the coils and the other end of each of the coils are connected with a power supply line, which can save winding time and can lead the coils to be uniformly arranged. A better property for a motor can be obtained.

Description

Stator coil

The utility model relates to a kind of stator coil, its for a kind of while with several enamelled wires on the magnetic pole seat around the coil that is rolled into, each number of turn of organizing coil is comparatively even in the distribution of locus, and the magnetic field that it produced also can comparatively be evenly distributed, and makes motor have excellent electrical characteristics.

The stator coil of existing motor can be divided into two kinds of the magnetic pole seat of the magnetic pole of radial pattern and coil structure and central siphon type and coil structures thereof, its existing coil mode is all with single line () the enamelled wire required coil groups number of reeling on each magnetic pole or magnetic pole seat, and the bridging line between each magnetic pole extracts in the coil stage casing, to meet designed motor characteristic.

The magnetic pole of radial pattern and coil structure thereof are as shown in Figure 1, 2, or as the bulletin the two or two First Five-Year Plan nine No. zero " structure of the stator of radiator fan " patent cases disclosed, the winding mode of its coil is to be wound on each magnetic pole with an enamelled wire respectively to organize coil, after coiling is finished, again the terminal of each group coil is done suitable connection in series-parallel and connect, come the CD-ROM drive motor rotor rotation so that can produce rotating magnetic field.Yet, though this magnetic pole and coil structure thereof can obtain uniformly Distribution of Magnetic Field,, the time that its coil-winding spent is longer, and the degree of difficulty of coiling work is also higher, and the impaired chance of enamelled wire is bigger, and fraction defective relatively also just improves.

The magnetic pole seat of central siphon type and coil structure thereof disclose as announcing the 27336 No. zero " motor fan structure " patent case, the winding mode of its coil also is with an enamelled wire required coil groups number of reeling on the magnetic pole seat, after coiling is finished, again the terminal of each group coil is done predetermined connection, to obtain the required rotating magnetic field of motor running.In this magnetic pole and coil structure thereof, though the required time time weak point more required of coil-winding than the pole coil coiling of radial pattern, and the degree of enamelled wire damage is also lower; Yet, the Distribution of Magnetic Field that pole coil produced of this kind central siphon type is unequal, especially the magnetic pole of the stator of multi-thread group of coil of three-phase is constructed, because coil is reeled toward outer gradually by internal layer, therefore, the locus of each group coil is all inequality, the number of windings of coil the more, the Distribution of Magnetic Field that it produced is more unequal, can seriously have influence on the motor characteristic of motor, even motor can't be turned round.

Main purpose of the present utility model is to provide a kind of stator coil, and its coil for being wound into several enamelled wires simultaneously can once be finished the coiling work of all coils simultaneously, shortens the coil-winding time in a large number.

Another purpose of the present utility model is to provide a kind of stator coil, organizes coil more and is reeled toward outer by internal layer simultaneously, and it is comparatively even that each organizes the Distribution of Magnetic Field that coil produces.

Another purpose of the present utility model is to provide a kind of stator coil, and the enamelled wire that utilizes different colours is respectively organized the end of a thread or the line tail of coil with identification, makes the phenomenon that the connection of respectively organizing coil can confusion reigned.

The purpose of this utility model is achieved in that promptly provides a kind of stator coil, and it is the coil that is wound on the stator seat of magnetic pole with enamelled wire; Described stator coil is reeled simultaneously with several enamelled wires and is formed, and an end of each coil interconnects, and is connected to the power supply line road jointly with the other end.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is the plane graph of existing stator coil;

Fig. 2 is existing stator coil connection diagram;

Fig. 3 is the stereogram of the utility model stator coil;

Fig. 4 is the utility model stator coil connection diagram one;

Fig. 5 is the utility model stator coil connection diagram two;

Fig. 6 is the utility model stator coil connection diagram three.

At first see also shown in Figure 3ly, the utility model is with the magnetic pole stator seat 1 of the central siphon type pedestal as coil-winding.No matter how much winding quantity of coil is, it is as the criterion with required coil groups number, with several enamelled wires (the group number of quantity sight line circle and decide) once side by side close wind on stator seat 1.Therefore, no matter how many group numbers of coil is, its coiling is exactly the number of turn of coil once to be reeled finish required time, promptly is that all coils are all accused and finished.That is to say, the group number of coil the more, the coiling time of being saved is the more.

Shown in Fig. 3,4 stereogram and the wiring schematic diagram that is wound into two groups of coils with two enamelled wires simultaneously.With two enamelled wires once side by side close wind on stator seat 1, each group coil all leaves two leading-out terminal V1, V0 and V2, V0, leading-out terminal V0 with two groups of coils connects into common ground again, and is connected to the power supply line road jointly with other end V1, V2.

This winding mode is except can saving the coiling time, and each group coil locus on stator seat 1 distributes also more even, and therefore, the Distribution of Magnetic Field that it produced is also comparatively even, and the motor characteristic of motor is also preferable.

In order to distinguish the leading-out terminal of respectively organizing coil, make unlikely generation confusion phenomena, the utility model can use the enamelled wire of different colours as the identification between each group coil.

See also shown in Figure 5ly again, it is the wiring schematic diagram of three groups of coil delta connections of three-phase.It is wound on after the stator seat 1 so that three enamelled wires are once parallel simultaneously, and every group of coil leaves two leading-out terminal V1, V0, V2, V0 and V3, V0; Be as shown in Figure 5 with the three-phase delta connection, the V1 that respectively goes between, V2, V3 that this three-phase △ connects then are connected to the power supply line road again.

See also shown in Figure 6ly again, it is the wiring schematic diagram of three groups of coil Y of two-phase connection.Its winding mode is with shown in Figure 5 identical, and after coiling was finished, with leading-out terminal V1, the V0 of each coil, V2, V0 and V3, V0 made the Y connection again, and each lead-out wire V1, V2 after the connection, V3 are connected to the power supply line road again.

In sum, the utility model is side by side once reeled all coils and is finished with the enamelled wire of several different colours, not only save the coiling time in large quantities, and the distribution uniform of coil, the Distribution of Magnetic Field that is produced is also more even, and the motor characteristic is also preferable.
