Embodiment Construction

[0038] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] Such as figure 1 , 2 , as shown in 3,

[0040] In this technical plan, mica tape is selected to wrap copper flat wire 1 to wind the coil, and epoxy glass mica tape with less adhesive powder (5442-1) and epoxy polyester film with less adhesive powder mica tape (5442-1) with less adhesive composition 0.13mm thick and 25 mm wide (5442-1D) Four layers of mica insulation layer 2 are mixed and half-stacked outside the coil as the coil. The thickness of one side of the mica insulation is 1.04mm, and a layer of 0.08mm thick and 25mm wide is flat-wrapped outside the coil mica insulation layer 2. The anti-halation tape is used as the protective insulating layer 3, the main insulating layer of the coil is composed of the coil mica insulating layer 2 and the protective insulating layer 3, and the thickness of one side of the main insul...

Abstract

The invention relates to a high-voltage motor shaped coil and a processing method thereof, in particular, a 6KV high-voltage motor shaped coil and a processing method thereof. The single-side insulation thickness of a domestic mature and reliable 6KV (F-grade) high-voltage motor shaped coil is 1.72mm. The coil of the invention is fusiform and includes two end portions and a straight portion; the coil is composed of a plurality of flat copper wires wrapped by an insulating material, a mica insulating layer wrapping the plurality of flat copper wires and a protective insulating layer wrapping the mica insulating layer. The 6KV high-voltage motor shaped coil is characterized in that a certain number of mica insulating belts are wound in a half-lapped tapping manner so as to from the mica insulating layer, wherein the number of the mica insulating belts is smaller than or equal to 6; the thickness of the mica insulating layer is smaller than or equal to 1.3 mm; the mica insulating layer and the protective insulating layer form a coil main insulating layer; the thickness of the coil main insulating layer is smaller than or equal to 1.5 mm; and the straight portion of the coil is immersed in resin. With the 6KV high-voltage motor shaped coil and the processing method thereof provided by the technical schemes of the invention adopted, the size and the manufacturing cost of a motor can be deceased.

Description

technical field [0001] The invention relates to a forming coil of a high-voltage motor and a processing method thereof, in particular to a forming coil of a 6KV high-voltage motor and a processing method thereof. Background technique [0002] Domestically mature and reliable 6KV (Class F) high-voltage motors form a single-side insulation thickness of 1.72mm. Some motor manufacturers are limited by the design of the insulation structure. The single-side insulation thickness of the coil may reach about 2.0mm. As we all know, the future development direction of motors is small size, high power and high efficiency. The power of the motor increases with the increase of the slot utilization rate; the volume of the motor decreases with the increase of the slot utilization rate; the efficiency of the motor increases with the increase of the slot utilization rate. Therefore, how to improve the utilization rate of motor slots has become the focus of research by motor manufacturers in...
