Description

Technical Field

[0001] The utility model belongs to the field of motors, relates to a stator and rotor, and particularly relates to a split stator and rotor. Background Art

[0002] A motor mainly consists of three parts: a stator, a rotor, and a sensor. The stator mainly consists of a stator core with winding grooves and stator windings wound in the windings. The structure of the annular integral stator punching sheet laminated into the stator core is such that a number of winding grooves are punched in the annular sheet material. This integral stator structure design has the following defects: Due to the influence of the winding groove structure, there is a certain process difficulty when entering the windings into the winding grooves, the winding step is difficult, and the design of the stator and winding groove structure is more difficult during the winding process. It is necessary to wind each winding separately and then weld it, which increases the process steps, increases the labor cost of workers, and seriously affects the production efficiency. At the same time, when one winding is damaged, the entire stator and rotor need to be scrapped. Summary of the Invention

[0003] The purpose of the utility model is to provide a split stator and rotor to solve the above problems for the existing problems in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A split stator and rotor includes a stationary stator member, a rotatable rotor member, and a shaft body connected by drive. There is a moving gap between the stator member and the rotor member. It is characterized in that the stator member is arranged in a split splicing structure;

[0005] The stator member includes a number of winding blocks for winding leads, two stator rings for limiting and fixing the winding blocks, and a number of fixing pins for fixing;

[0006] The corresponding end of the winding block axially extends outward to form a connection platform for splicing and fixing;

[0007] Limit grooves for limiting are opened at the upper and lower ends of the connection platform;

[0008] A number of opening grooves are opened on the two stator rings and are matched with the connection platform;

[0009] Fixing holes for the fixing pins to pass through are opened on both the stator ring and the connection platform. Among them, the fixing holes on the stator ring are located at the bottom of the opening groove;

[0010] A limiting step matched with the limiting groove axially extends upward on the opening groove;

[0011] In the above-mentioned split stator and rotor, the connection platform and the winding block are of an integrally formed structure, and the longitudinal section is arranged in an "I" - shaped structure.

[0012] In the above-mentioned split stator and rotor, the stator part and the rotor part are coaxially structured, and the shaft body passes through the central part of the rotor part. The two stator rings are arranged in a relative structure and are fixed to each other through the fixing hole and the fixing pin structure.

[0013] In the above-mentioned split stator and rotor, the number of winding blocks is equal to the number of opening slots, and they cooperate with each other through the limiting slot and the limiting step structure to realize the radial limitation of the winding blocks.

[0014] Compared with the prior art, the structure of this split stator and rotor is simple. By using the cooperation design of the stator ring, the winding block and the fixing pin structure, the limiting and fixing installation of the winding block can be effectively realized. The winding process is convenient and simple, reducing the production and manufacturing difficulty, effectively reducing the labor force of manual winding, improving the production efficiency, and at the same time, reducing the wear and scrap rate.
