Abstract

The invention discloses a split type stator core structure and a splicing method. The structure includes a full circular stator core; The full circular stator core includes multiple stator core splitstructures that can be spliced together into a full circle; each of the stator core split structures includes multiple stator split punching sheets; each of the stator split punching sheets includes an arc yoke portion and multiple notch teeth; the multiple notch teeth are uniformly distributed on the inner ring of the yoke portion; notches are formed between the adjacent notch teeth; one end of the yoke portion is provided with a process groove, and the other end is provided with a process boss; the outer ring of the yoke potion is provided with a positioning groove and a first welding groove; and the yoke portion and the notch teeth are provided with multiple self-buckling points, and the multiple stator split punching sheets are overlapped with each other by the self-buckling points toform the stator core split structures. The split type stator core structure is high in the utilization rate of materials, enables the stamping force to be greatly reduced, and be mass-produced by a small-tonnage high-speed punching machine; and the size, form and location tolerance and structure strength of the split type stator core structure are conveniently controlled by the positioning grooveand by performing welding on each of the first welding grooves.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a split stator core structure and splicing method. Background technique [0002] The stator assembly of the servo motor can be designed differently according to the rotor assembly. Regardless of the stator rotor sleeve punching sheet or the independent integral stator punching sheet, they are all processed by integral punching and blanking. After punching, the blanking head of the inner hole is wasted and the utilization rate of raw materials is low. Stator-rotor sleeve punching or integral stator punching structure has a large punching force, requires a large punching tonnage, and the corresponding punch production equipment and punching dies are also large. Therefore, a stator split structure is needed to solve the above problems, but the stator split punches need to be spliced ​​into a whole after stamping, and the corresponding product size, shape tolerance and strength contr...
