Embodiment 1

[0023] In Example 1, the polygonal enameled wire is hexagonal. Enameled wires formed with other polygons still fall within the scope of the present invention.

[0024] The polygonal enameled wire in the present invention can be used for electromagnetic windings, image 3 It is a schematic diagram of the comparison between the circular enameled wire and the hexagonal enameled wire in the motor stator. From image 3 It can be seen from the partial sectional view of the stator core of the motor, wherein the slots on both sides of the stator teeth 6 have the same area, and two kinds of enameled wires are respectively placed: the circular enameled wire in the prior art and the hexagonal enameled wire in the present invention. The circular enameled wire 3 is placed on the left side of the stator tooth 6 . The hexagonal enameled wire 4 is placed on the right side of the stator tooth 6 (of course, other polygons can also be placed). Obviously, with the polygonal enameled wire, the...

Abstract

The invention provides a polygonal enamel wire for an electromagnetic winding. The polygonal enamel wire comprises a metal conductor arranged in the polygonal enamel wire body and an insulation paint film arranged outside the polygonal enamel wire body. The metal conductor is formed through a special wire drawing die to be polygonal. According to the technical scheme, the polygonal enamel wire has the advantages that by means of the polygonal enamel wire, the space utilization rate can be improved, and the purposes of reducing the device size and lowering cost and the like are achieved.

Description

technical field [0001] The present invention relates to a polygonal enameled wire, in particular to a polygonal enameled wire for electromagnetic windings and a motor using the same. Background technique [0002] Enameled wire is an electrical material, which is the main and key raw material for electromagnetic windings of motors, transformers, electrical appliances and other devices. The enameled wire is composed of a metal conductor and an insulating layer. The bare metal wire is annealed and softened, and then painted and baked many times. At present, domestic enameled wires are divided into round wires, flat wires, and hollow wires according to their shapes, and round wires are the most widely used. If circular enameled wire is used as the electromagnetic winding, the gap between adjacent wires and the gap between the conductor and the core is very large, and this part of the space is hardly utilized. This reduces the effective utilization of space, and in order to mee...
