Description

TECHNICAL FIELD

[0001] The utility model relates to direct current brushless motor technical field especially relates to a novel solar alternating current brushless motor structure. BACKGROUND

[0002] As Figure 1 The existing solar alternating current brushless motor structure includes upper winding frame 1, lower winding frame 2, the upper winding frame, lower winding frame are oppositely inserted in the top and bottom of stator core, the upper winding frame, lower winding frame include annular frame 3 respectively, a plurality of winding blocks 4 are evenly arranged in the annular frame along the circumference, and winding notches 5 are formed between adjacent two winding blocks. The insertion part 6 is arranged in the winding slot and protrudes along the outer edge of the winding slot. As Figure 2 The insertion part is used for the wiring port 8 of the top and bottom of stator core 7. In order to ensure the insulation between the stator core and the winding coil, the insulation paper is placed in the wiring port of the top and bottom of stator core during winding, and the insulation upper winding frame and lower winding frame are wound.

[0003] However, in order to ensure that the winding wire does not contact the stator core, the insulation paper needs to be in contact with the insertion part of the upper winding frame and the lower winding frame without seamless connection, which requires high precision. The existing insulation paper usually has deviation in size. If the length is too long, the contact part will be extruded, affecting the installation. If the length is too short, the winding wire will contact the stator core, resulting in the probability of electric leakage of the solar coil during power running. This has a great influence on testing and product development and exists certain safety problems. UTILITY MODEL CONTENTS
