Description

A kind of motor stator structure

Technical field

The utility model belongs to electric machine structure technical field, and in particular to a kind of motor stator structure.

Background technique

In the motor stator technical field of the prior art, a kind of stator is assembled by the cooperation of inner stator and external stator To form the stator with arch ring structure, arch ring structure can cut the magnetic field between adjacent stators tooth, but the arch Coil structures also become in inner stator and external stator fit tolerance assembling, and rigidity is minimum and is easiest to the position to deform.Because The motor stator being mainly assembled to form by inner stator and external stator, inner stator and external stator are assembled in the form of being interference fitted, When inner stator is assembled with small shrink amount inside indentation external stator, the arch bridge portion with open arch ring is easy by adjacent fixed The mutual extrusion of sub- tooth and deform, in this way be easy so that the perforation of default subcenter is deformed by circle, to cause Combined stator circularity and concentricity are deteriorated, and after the completion of motor practical set, the rotor for penetrating perforation is easy and the perforation of deformation Edge scrapes, non-uniform air-gap between rotor and combined stator, lacks to clamping stagnation, abrasion, abnormal sound, electromagnetic noise etc. occur It falls into, and seriously affects the service life of motor.

Utility model content

For the above technical problems, the utility model provides a kind of motor stator structure, existing fixed to solve There is the problem of abrasion, abnormal sound there are central hole deformation in subassembly structure, the motor stator structure can reduce inner stator and The assembly difficulty of external stator, the problems such as avoiding the occurrence of deformation.

The utility model provides a kind of motor stator structure, including external stator and inner stator, and the external stator is rectangular Structure, is formed with the square hole for installing the inner stator in the middle part of the external stator, and the inner stator includes inner ring, multiple First divider arms and multiple second divider arms, the inner ring are cirque structure, multiple first divider arms matrix in a ring It being connected on the outer wall of the inner ring, matrix is connected on the outer wall of the inner ring multiple second divider arms in a ring, and It is spaced apart from each other between multiple first divider arms and multiple second divider arms, the first adjacent divider arms and second separate It is formed between arm around line chamber, multiple T-slots is provided on the inner wall of the external stator, first divider arms are far from described interior The end of circle is provided with T forming head, and the T forming head is embedded in the T-slot, the end of second divider arms far from the inner ring It is resisted against on the inner wall of the external stator.

Further, the quantity of first divider arms is four, and the quantity of second divider arms is four, four institutes It states the second divider arms and bears against four Angle Positions in the square hole, first divider arms divide equally two neighboring second point Angle between arm.

Further, four Angle Positions of the square hole are rounded structure, and second divider arms are far from the inner ring End be formed with arcwall face, the arcwall face is adapted with the Angle Position shape of the square hole.

This motor stator structure is provided with inner stator and external stator, and multiple T shapes are provided on the inner wall of the external stator Slot is provided with T forming head in the end of the first divider arms, when carrying out the assembly of inner stator and external stator, can pass through the T forming head The be fastened inner stator and external stator between the T-slot effectively reduce assembly difficulty, improve assembly efficiency, Tradition interference fit bring problem on deformation is avoided, while multiple second divider arms can be formed the default minor structure Support and positioning, guarantee its assembly precision.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is a kind of structural schematic diagram of motor stator structure.
