Abstract

The utility model provides a servo motor's novel stator and servo motor, include: stator core, winding, stator core buckles from beginning to end by the strip iron core along circumference, and the joint constitutes, the strip iron core includes consecutive a plurality of iron core cell cubes, the iron core cell cube includes the yoke constitution body and denticle, be provided with the winding on the denticle, the yoke of adjacent iron core cell cube is constituteed and is linked to each other between the body. The utility model discloses simple structure, the automatic wire winding of convenience realization improves the winding quality, and through the welding formation stator of outer convex ring and interior scrobicular ring, the connection is convenient, and the good reliability makes the stator quality obtain improving, and simultaneously, the tooth pitch that formation was located to adjacent stator prong is very little for the tooth's socket torque is little, reduces the noise and the vibration that lead to the fact because of the tooth's socket torque, makes the stator performance get a promotion.

Description

The Novel stator of servomotor and servomotor

Technical field

The utility model relates to the stator field of motor, particularly, relates to Novel stator and the servomotor of servomotor.

Background technology

At present, motor stator generally has two kinds of structures, and one is monolithic construction, and another kind is carried out being built up stator by stator punching.The first structure winding carries out by notch the formation winding that rolls off the production line, and rolling off the production line is generally by manual operations, and end of rolling off the production line needs shaping, there is coiling poor quality, defect that time-consuming waste material is taken a lot of work; The second stator structure also exists error when stator lamination between stator punching, and superimposed operation is loaded down with trivial details, reduces stator total quality.

Therefore, be necessary to improve the stator structure of servomotor.

Utility model content

For defect of the prior art, the purpose of this utility model is to provide a kind of Novel stator and servomotor of servomotor.

According to the Novel stator of a kind of servomotor that the utility model provides, comprising: stator core, winding;

Stator core circumferentially bends head and the tail joint by strip iron core and forms;

Described strip iron core comprises the multiple iron core unit bodies be connected successively;

Iron core unit body comprises yoke composition body and denticle; Described denticle is provided with winding;

Be connected between the yoke composition body of adjacent iron cores cell cube;

The yoke composition body of described multiple iron core unit body forms the yoke portion of stator core;

The denticle of described multiple iron core unit body forms the stator tooth of stator core.

Preferably, between the opposite flank of the yoke composition body of adjacent iron cores cell cube, be connected to form junction between the exterior lateral area of opposite flank, be separated between the inside region of opposite flank and form groove between yoke.

Preferably, between yoke, groove comprises circular groove.

Preferably, in strip iron core, be fixedly connected with by the outer bulge loop matched, interior scrobicular ring between the opposite face of the yoke composition body of two iron core unit bodies at head and the tail two ends.

Preferably, in stator core, the minimum spacing between the denticle of adjacent iron cores cell cube is less than 0.4mm.

Preferably, the outside wall surface of iron core unit body is arc surface, and the outside wall surface of each iron core unit body forms the face of cylinder.

Preferably, stator slot is formed between the denticle of adjacent iron cores cell cube

According to a kind of servomotor that the utility model provides, comprise the Novel stator of above-mentioned servomotor.

Compared with prior art, the utility model has following beneficial effect:

1, the utility model structure is simple, can realize stator Automated winding, and improve winding mass, outer bulge loop and interior scrobicular ring are by being welded together, and connected mode is easy and reliability is high, improves stator quality.

2, split type stator tooth is formed stator by winding by the utility model, and the tooth root spacing of adjacent stators tooth is very little, and cogging torque is little, thus the noise reduced because cogging torque produces and vibration, stator performance is got a promotion.
