Embodiment Construction

[0013] Attached below Figure 1-4 Further explanation of this stator split AC servo motor:

[0014] refer to Figure 1-2

[0015] The single split stator core 1 is in the shape of a "worker". The two ends of the yoke of the stator core 1 are provided with protrusions 6 at one end, and the other end is provided with a groove 4 that is compatible with the protrusions 6. The middle part is partially toothed and multi-piece The stator core 1 is stacked together, the winding 3 is directly wound on the teeth of the stator core 1, two nails 5 are set on the yoke of the stator core 1, and two nails 7 are set on the teeth of the stator core 1.

[0016] refer to image 3 :

[0017] According to design requirements, the number of multiple sets of stator slots is a multiple of 3. Preferably 9 slots, 15 slots, 18 slots or 27 slots. The grooves designed in this embodiment are tens of 18 grooves. The split stator core 1 is combined and assembled as a whole through a tightening device....

Abstract

A stator-split alternating-current servo motor comprises two end covers, an engine base, stators, and a rotor. The stator-split alternating-current servo motor is characterized in that the stators are of a split structure, stator cores (1) are 'H'-shaped, the two ends of the yoke part of each stator core (1) are respectively provided with a bulge (6) and a groove (4) matched with the bulge (6), a winding (3) is directly wound on the tooth part of each stator iron core (1), and multiple split stators are combined and assembled into a whole. The cost, energy and raw materials are greatly reduced, the efficiency is improved, and the size of the motor is greatly reduced.

Description

technical field [0001] The stator split AC servo motor belongs to the field of 30-55KW high-power AC servo motors. It can be widely used in industries with large energy consumption such as oil fields, mines, construction, and plastic spinning. technical background [0002] For high-power AC servo motors, due to various reasons such as the technical level of the factory and large investment, the stator still adopts an integral punching structure. Since the stator punching material is made of 0.35mm low iron consumption silicon steel sheet, its price is nearly twice as expensive as that of ordinary silicon steel sheet. The traditional motor still adopts the integral structure of the stator, and its material utilization rate is very low, resulting in a sharp increase in the cost of the whole machine. Moreover, this mechanism cannot further increase the stator's embedding groove rate and reduce the copper consumption of the motor. Contents of the invention [0003] The ...
