Background technology
At present, the stator coil winding of permanent-magnet brushless DC electric machine adopts copper enamelled wire, and the density of its material own is high, and hardness is large, add the shaping difficulty after rule, and weight is large; Copper material belongs to narrow resources in China, expensive, and meet security performance and the power performance index of motor winding on an equal basis, its deficiency in economic performance, reduces the market competitiveness of permanent-magnet brushless DC electric machine.In addition, because stator coil winding adopts copper enamelled wire, cause stator coil structure unreasonable, loss is large.
Utility model content
The utility model object is to provide a kind of permanent-magnet brushless DC electric machine copper-clad aluminum conductor coil structures, and iron core is formed by multi-disc stator punching is superimposed, makes one by the welding locating welding groove to foreign round; Winding adopts copper-in-aluminum enameled wire, instead of the copper enamelled wire in primary winding, does not change rule structure, solves Problems existing in background technology.
The technical solution of the utility model is:
Permanent-magnet brushless DC electric machine copper-clad aluminum conductor coil structures, comprise stator core and winding, described winding is that copper-in-aluminum enameled wire is coiled into, described stator core is formed by multiple stator punching is superimposed, stator iron core tooth groove is equipped with in stator punching, stator punching excircle is provided with welding groove, and two welding grooves are close together and arrange in pairs; The stator core excircle that multiple stator punching is overlapped into forms two welding grooves be parallel to each other, and welding groove center line stator core axis is in tilted layout; Multiple stator punching is welded into as a whole by welding groove place, forms stator core, stator core inner ring is formed stator core teeth groove, and winding embeds in stator core teeth groove.
Described copper-in-aluminum enameled wire, its structure from inside to outside be thread core of aluminum, layers of copper, tin coating and insulating barrier successively.
Described stator punching outer shroud is provided with labeled slots, carries out superimposed by labeled slots to stator punching, and stator punching is provided with lamination insulation layer.
The utility model stator punching is by making one to the welding of welding groove, adopt argon arc welding welding, welding and assembling height is no more than stator cylindrical; Winding adopts copper-in-aluminum enameled wire, is embedded in the middle of stator core teeth groove by rule requirement, and whole operating process does not allow to destroy lamination insulation layer, does not affect all properties of motor.
The beneficial effects of the utility model are: stator core stamping sheet offers multipair welding groove, are welded together after stator punching is superimposed by welding groove, therefore can reduce the slot effect of motor, ensure that machine operation is steady.Copper-in-aluminum enameled wire density is 1/3 of the pure copper wire of identical wire diameter, significantly reduces the weight of coil.After using copper-in-aluminum enameled wire instead by copper enamelled wire, a large amount of expenses can be saved, improve the competitiveness of product, for enterprise increases considerable economic benefit.The DC resistivity of copper-in-aluminum enameled wire is about 1.5 times of pure copper wire; Loss corresponding increase 6-10% in coil, efficiency reduces about 1%.Copper-in-aluminum enameled wire, due to the concentric coated one deck fine copper in its surface, therefore has with the same braze ability of pure copper wire, and need not do special processing as pure aluminum wire.
