Abstract
The utility model discloses a permanent magnet synchronous motor stator, which comprises a stator core and a coil. Each pole of the stator adopts a concentrated winding to form a single coil; the coilof each pole is a standard coil; N coils form a motor stator and form a three-phase winding with different voltage levels by adopting the serial or parallel connection mode; and the motor stator cancorrespond to the axial length of a motor rotor by increasing the lamination thickness of a silicon-steel plate so as to form different motor power series. The permanent magnet synchronous motor stator has the benefits that the motor stator is composed of N standard stators, the standard stator not only saves materials, but also realizes scale production very conveniently, therefore the labor productivity can be evidently improved, the manufacturing cost can be reduced, and the performance is superior. The permanent magnet synchronous motor stator can be widely used in various electronic equipment which needs low speed and high torque, such as an electric vehicle, a mine electric locomotive and small wind power generating equipment.
Description
Technical field
The utility model relates to a kind of New-type electric machine technical field, is specially a kind of permanent-magnetic synchronous motor stator of the combined stator structure of being made up of the standard stator coil unit.It can be widely used in electric automobile, mine electric locomotive, small-size wind power-generating equipment etc. needs in each class of electronic devices of low speed high torque.
Background technology
The traditional stator core construction form of the general employing of the stator of magneto; stator punching and iron core are made by the disposable punching press of combined type progressive die; stator core itself is fit to large-scale production; low cost of manufacture; its defective is: because stator generally adopts the short distance distributed winding; be not easy to use automatic coil winding machine to carry out large-scale production; significantly increased the manufacturing cost of stator winding; particularly, insulation do not reach requirement just in case appearring in the somewhere of stator winding; or other problems appears; to cause all coilings again of all stator winding, this will cause material and artificial huge waste.
The utility model content
The present invention mainly is the technical problem of the above-mentioned large-scale production of solution, provides a kind of simple in structure, can use the automation coil winding machine to carry out the permanent-magnetic synchronous motor stator of large-scale production.
The purpose of this utility model is achieved through the following channels: a kind of permanent-magnetic synchronous motor stator, motor stator is made up of some groups of stator units, stator unit comprises the coil of coiling on stator core and the stator core, stator core head one side is a plush copper, the head opposite side is an emarginated tail, and the meshing linking of several stator core heads pieces together completely circular structure.Coil on the stator core is independent coiling, and coil constitutes three phase windings of different electric pressures by the lead connection in series-parallel.Add the multilayer silicon steel laminations on the motor stator, the thickness of silicon steel laminations is corresponding with the axial length of rotor.
A kind of permanent-magnetic synchronous motor stator of the utility model has the following advantages:
(1) can utilize the banding pattern silicon steel sheet to manufacture stator core, adopt high velocity ram machine to carry out punching, both the economical with materials cost was also increased work efficiency simultaneously;
(2) can adopt the automation coil winding machine to carry out coiling, conveniently accomplish scale production, thereby can raise labour productivity significantly and reduce manufacturing cost;
(3) each winding insulation processing separately, technology is very simple;
(4) every standard coil all can adopt flat type lead to carry out coiling, compares with the rule mode of conventional motor, has shortened the tip lengths of stator coil, both can save the copper consumption more than 20%, can also reduce the leakage reactance of stator winding, and motor performance is more excellent.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of permanent-magnetic synchronous motor stator of the present utility model;
Fig. 2 is the structural representation of stator unit 5.
Embodiment
As shown in Figure 1 and Figure 2, a kind of permanent-magnetic synchronous motor stator of the utility model, it includes several special stator cores 3 that have plush copper 1 and emarginated tail 2 and coil 4 is formed.The coil 4 of each stator core 3 all is independent coilings, forms single standard stator unit 5; To get the emarginated tail 2 of another stator unit 5 mutually meshing with being arranged in the front with plush copper 1 respectively for several stator units 5, is combined into a motor stator 7; Each coil 4 carries out connection in series-parallel by lead 8 and lead 6 as required, to constitute three phase windings of different electric pressures.
