Problems solved by technology
[0002] Although there is no need to use a commutator in a brushless motor, a brushless connecting piece is still used in many brushless motors. The structure and process of the current brushless connecting piece are very complicated, and most of them use bakelite powder and The commutator piece is pressed and formed. This process is prone to the problem of powder residue, and the

The present invention relates to a brushless connection sheet and a processing technology thereof. The brushless connection sheet comprises a base body and commutator segments, the base body is in anarc and sheet shape, slots having openings at one ends are uniformly distributed on the cambered surface of the upper side of the base body along the circumference, each commutator segment is in a strip shape, one end of each commutator segment is provided with a hook-shaped portion, the other end of each commutator segment is provided with a right-angle edge folding portion, insertion bosses matching with the slots are transversely arranged at the lower ends of the commutator segments, the plurality of commutator segments are inserted into the corresponding slots from one ends of the hook-shaped portions, and separation bosses are arranged on the base body between the adjacent commutator segments. The brushless connection sheet and the processing technology thereof are few in processing technology, relatively easy in technology operation, can bear the high temperature and has an isolation short-circuit prevention isolation effect.
Description
technical field [0001] The invention relates to the field of brushless motor accessories, in particular to a brushless connecting piece and a processing technology thereof. Background technique [0002] Although there is no need to use a commutator in a brushless motor, a brushless connecting piece is still used in many brushless motors. The structure and process of the current brushless connecting piece are very complicated, and most of them are made of bakelite powder and The commutator segment compression molding process, this process is prone to the problem of powder skin residue, and the matrix has poor encapsulation and isolation of the commutator segment. When the product is spot welded, it is often unable to withstand relatively high temperatures, and the product is easily damaged. Breakdown, and the current brushless connecting piece does not have an isolation structure between the commutator segments, so a short circuit between the commutator segments is prone to o...
