Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, an insulation frame for a small-sized motor includes:

the framework main body 1 is made of an insulating material;

outer lane 2 and inner circle 3, skeleton main part 1 is constituteed with inner circle 3 to outer lane 2, and outer lane 2 and inner circle 3 are the ring circle of circle, wherein:

the outer ring 2 is sleeved on the outer side of the inner ring 3, annular grooves 4 are formed in the upper side face and the lower side face of the inner ring 3, a plurality of winding holes 5 are formed in the bottom groove wall of each groove 4 in an equiangular mode in the circumferential direction and used for winding, and the winding holes 5 are four-fifths of a circular hole.

As shown in fig. 1, the inner wall of the outer ring 2 is provided with a limiting block 6, the groove wall of the groove 4 of the inner ring 3 is further provided with a limiting groove 7, and the limiting block 6 is inserted into the limiting groove 7.

Through adopting above-mentioned scheme, when covering outer lane 2 to inner circle 3, stopper 6 injects the spacing effect of playing in spacing groove 7, improves the installation accuracy between inner circle 3 and outer lane 2.
