Abstract

The utility model relates to the field of the motor technology, and specially relates to an improved AC PMSM centralized coiling stator structure, including a plurality of approximately I-shaped punching sheets. The top view or upward view of the punching sheets is approximately I-shaped, the punching sheets are assembled and overlapped according to a certain rule to form a one pole coiling set, wherein one side is convex at the upper and lower portion, and is concave at the middle, and the other side is convex at the middle, thereby the utilization rate of the siliconized plate is raised, simultaneously, the coiling set employs the re-combination coiling technology of a single coiling set, the machining efficiency is substantially raised, a plurality of single coiling sets are distributed at the circumference, and are cooperated and assembled to form a ring shape through rasping teeth, a plurality of inner notches are uniformly distributed on the formed ring along the circumference, simultaneously, a combined structure is employed for the stator, the siliconized plate material utilization rate is substantially raised, and the coiling production efficiency is enhanced.

Description

A kind of modified model AC permanent magnet synchronous motor is concentrated the wound stator structure

Technical field:

The utility model relates to technical field of motors, and particularly a kind of modified model AC permanent magnet synchronous motor is concentrated the wound stator structure.

Background technology:

The AC magnetoelectric machine stator can be divided into two types according to winding configuration, and the one, the characteristics of centralized winding: the end winding is little, and copper consumption is little; 2, the back-emf non-sine distributes; 3, phase current non-sine, harmonic wave is big; The 2nd, the characteristics of distributed winding: 1, the end winding is big, and copper consumption is big; 2, back-emf Sine distribution; 3, phase current is sinusoidal, and harmonic wave is little.Adopt the drawback of two types of above windings: the wire winding more complicated, cost is high.The silicon steel sheet material utilance is low.

The utility model content

In order to overcome the above-mentioned weak point that exists in the conventional AC permagnetic synchronous motor technology; The purpose of the utility model is to provide a kind of modified model AC permanent magnet synchronous motor to concentrate the wound stator structure; It is little that it has inherited traditional concentrated winding overhang winding; The characteristics that copper consumption is little have overcome the shortcoming that the back-emf non-sine distributes again, have taken into account the raising of motor rotation stationary performance and energy conversion efficiency; Stator adopts combining structure simultaneously, has solved the problem of coiling production efficiency when having improved the silicon steel sheet material utilance greatly again.

In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: a kind of modified model AC permanent magnet synchronous motor is concentrated the wound stator structure, comprises that a plurality of differences roughly are the punching composition of I shape; Said punching is meant that the shape of vertical view or upward view is roughly I shape, and combination laminates according to certain rules in said punching, is the middle concavity that is of convex up and down Yi Bian form; The centre of another side is the one pole winding of convex; Play the effect that magnetic field excessively steadily is connected like this, the motor stator that adopts many group one pole windings to form is when having improved the utilance of silicon steel sheet so greatly; Coiling adopts single group to wind the wire winding of combination again; Make working (machining) efficiency improve greatly, organize circumferential distribution of one pole winding more and be assembled into ring-type that the ring-type that forms is evenly distributed with a plurality of inner tank mouths along circumference through frustrating the tooth cooperation.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is that the A-A of Fig. 1 is to explosion views.

Fig. 3 is the structure chart of the different punchings of the utility model one pole winding.

Fig. 4 is the structural representation of the utility model one pole winding.

Below in conjunction with accompanying drawing the utility model is done further to specify.

Embodiment

Like Fig. 1, shown in Figure 2, a kind of modified model AC permanent magnet synchronous motor is concentrated the wound stator structure, adopts many group one pole windings 2 logical teeth of frustrating that circumferentially distribute to cooperate the motor stators that are assembled into ring-type, the ring-type that forms be evenly distributed with a plurality of inner tank mouths 3 along circumference.

As shown in Figure 3, a kind of modified model AC permanent magnet synchronous motor is concentrated the wound stator structure, comprises that a plurality of differences roughly are punching 1 composition of I shape, and said punching is meant that the shape of vertical view or upward view is roughly I shape.

As shown in Figure 4; A kind of modified model AC permanent magnet synchronous motor is concentrated the wound stator structure, and combination laminates according to certain rules in said punching 1, is the middle concavity that is of convex up and down Yi Bian form; The centre of another side is the one pole winding 2 of convex, plays the effect that magnetic field excessively steadily is connected like this.

What should explain at last is: above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.

Claims

1. a modified model AC permanent magnet synchronous motor is concentrated the wound stator structure; It is characterized in that: comprise that a plurality of differences roughly are the punching composition of I shape; Said punching laminates through combination, Yi Bian formation is concavity in the middle of being convex up and down, the centre of another side is the one pole winding of convex; Many group one pole windings circumferentially distribute and cooperate the motor stator that is assembled into ring-type through frustrating tooth, and the ring-type that forms is evenly distributed with a plurality of inner tank mouths along circumference.
