Manufacturing method of flat wound heat-radiation turn magnetic pole coil

Abstract

The invention relates to a manufacturing method of a flat wound heat-radiation turn magnetic pole coil. The manufacturing method of the flat wound heat-radiation turn magnetic pole coil comprises the steps that (1) narrow-specification common turns and wide-specification heat-radiation turns are respectively wound; (2) the common turns are sheared off in the positions of the heat-radiation turns according to the design requirements, one wire turn is sheared off from the well wound heat-radiation turn coil, and the shearing position is matched with the common turns; (3) the tail end of one common turn is welded to the matching end of the corresponding heat-radiation turn; (4) the other end of the corresponding heat-radiation turn is welded to the head end of the common turn of the next layer; (5) according to the design requirements, the common turns and the matched heat-radiation turns are welded circularly and alternatively until the whole coil is finished. The flat wound heat-radiation turn magnetic pole coil can be wound through a common winding machine, the two kinds of well wound wire turns are sheared and then alternatively welded to the position with the design requiring for the heat-radiation turns, and therefore the number of welding seams is largely reduced.

Description

technical field [0001] The invention relates to the field of motor coil manufacturing, in particular to a manufacturing method of an edge-wound heat-dissipating turn magnetic pole coil. Background technique [0002] The usual heat dissipation turn magnetic pole coil generally includes narrow ordinary turns and wide heat dissipation turns. Each layer of coil is surrounded by copper wires of the same width to form a rectangle. Multi-layer narrow ordinary turn coils and one layer of wide heat dissipation turn coils are welded alternately. An integral coil, due to the alternating width and narrow copper wire, it is difficult to continuously wind the copper wire into an integral coil with an ordinary winding machine. At present, the general production method is to use special welding equipment for welding. The disadvantages of this magnetic pole coil production method are: 1. Each turn of the coil is welded by 4 copper wires in one layer, and each layer of coil has four coils. W...

[0002] The usual heat dissipation turn magnetic pole coil generally includes narrow common turns and wide heat dissipation turns. Each layer of coil is surrounded by copper wires of the same width to form a rectangle. Multi-layer narrow common turn coils and one layer of wide heat dissipation turn coils are welded alternately. An integral coil, due to the alternating width and narrow copper wire, it is difficult to continuously wind the copper wire into an integral coil with an ordinary winding machine

At present, the general production method is to use special welding equipment for welding. The disadvantages of this magnetic pole coil production method are: 1. Each turn of the coil is welded by 4 copper wires in one layer, and each layer of coil has four coils. Welding seams, if a magnetic pole coil has 55 turns of coil, the whole coil has more than 200 welding seams, not only the processing time is long, but also there are too many welding seams, as long as one welding seam is defective, the whole coil is unqualified, so it is easy to appear Quality issues
