Abstract
The invention discloses a permanent-magnetic synchronous motor stator. The permanent-magnetic synchronous motor stator comprises a stator core and coils; each pole of the stator adopts concentrated windings to form a single coil, the coil of each pole is a standard coil, and N coils form the motor stator; the N coils are connected in series or in parallel to form a three-phase winding with different voltage levels; and the motor stator can correspond to the axial length of a motor rotor by increasing the lamination thickness of silicon steel sheets so as to form different motor power series. The permanent-magnetic synchronous motor stator has the advantages that: the motor stator consists of stators of N standard units, and the standard stators save more materials and are very convenient for scale production so as to remarkably improve the labor productivity and reduce the manufacturing cost; and the motor stator has very predominant performance, and can be widely applied to various electronic devices such as electric automobiles, mine electric locomotives, small wind power generation devices and the like which need low speed and large torque.
Description
Technical field
The present invention relates to a kind of New-type electric machine technical field, be specially a kind of permanent-magnetic synchronous motor stator of the combined stator structure of forming by 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.
Summary of the invention
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 objective of the invention is to realize: a kind of permanent-magnetic synchronous motor stator by following approach, 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 present invention 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 present invention is described in further detail:
Fig. 1 is the structural representation of permanent-magnetic synchronous motor stator of the present invention;
Fig. 2 is the structural representation of stator unit 5.
Embodiment
