AI Technical Summary
Technical Problem
The existing excitation rotor has the problem of being too large when installing insulating paper, and different specifications of iron cores require different plastic frames, which has poor versatility.
Method used
The structure adopts the combination of insulating skeleton and iron core. The insulating skeleton is connected to the iron core through the limit block, and the insulating paper is fixed by the slot to adapt to the iron core of different thicknesses. Plastic skeletons are used at both ends to adapt to the iron core of different heights.
Benefits of technology
The versatility of the excitation rotor is improved, it can adapt to iron cores of different specifications, and the installation process is simplified.

Abstract
The utility model discloses an excitation rotor slot bottom insulation structure, which comprises an iron core, a plurality of slots are arranged on the iron core, insulation paper is inserted in the slots, and the upper end and the lower end of the iron core are connected with insulation frameworks. Through grooves matched with the slots are formed in the two insulating frameworks; the side, close to the iron core, of the inner wall of the through groove is connected with a limiting block. The insulation framework is connected with the iron core in an inserted mode through the limiting block. A clamping groove is formed between the limiting block and the inserting groove. The insulation paper is arranged in the clamping groove; and the insulating paper is clamped with the iron core through the two insulating frameworks. According to the utility model, the insulation of the slot bottom is improved, the plastic frameworks are used at the two ends, the insulation paper is used in the middle of the slot, the height of the insulation paper is adjusted to adapt to iron cores with different thicknesses, and the plastic frameworks at the two ends can adapt to iron cores with different heights, so that the universality is improved.
