Abstract
The utility model relates to a novel motor winding, which comprises a coil, wherein the coil is formed by winding a wire, wherein the wire comprises an aluminium core and a copper layer covering outside the aluminium core. In the utility model, the copper layer is covered outside the aluminium core, not only is the wire conducting of the wire ensured, but also the advantage of the low density of aluminium is fully utilized, so that the weight and the size of the wire can be remarkably lightened.
Description
(1) technical field
The utility model relates to a kind of motor windings.
(2) background technology
In the prior art, be used for the electrical micro-machine of timer, water discharge dragging device, draining pump etc., its winding generally all adopts the copper cash coiling to form.The cost that its shortcoming that also exists is copper is higher, and the density of copper is bigger, and therefore for reaching the lead requirement, the copper cash bulking value is relatively large.
(3) summary of the invention
In order to overcome the deficiency of existing motor windings, the utility model provides a kind of New-type electric machine winding that alleviates coil weight, volume.
The technical scheme in the invention for solving the technical problem is: a kind of New-type electric machine winding, comprise coil, and described coil is formed by the lead coiling, and described lead comprises the aluminium core and is coated on copper layer outside the described aluminium core.
Further, described copper layer also is coated with insulating barrier outward.
The cross section of described lead can be pancake, and the cross section of described lead also can be circle, and the cross section of lead also can be other arbitrary shapes.
The beneficial effects of the utility model are: coat the copper layer outside the aluminium core, both guaranteed leading of lead
The property, made full use of the low density advantage of aluminium again, the weight and volume of lead is significantly alleviated.
(4) description of drawings
Fig. 1 is the cross-sectional view of lead of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of New-type electric machine winding comprises coil, and described coil is formed by the lead coiling, and described lead comprises aluminium core 1 and is coated on copper layer 2 outside the described aluminium core 1.Also can be at described copper layer 2 outsourcing insulating layer coating 3.The cross section of lead described in the present embodiment is circular, also can be pancake or other shapes certainly.
The utility model coats copper layer 2 outside aluminium core 1, both guaranteed leading of lead
The property, made full use of the low density advantage of aluminium again, the weight and volume of lead is significantly alleviated.
Claims (4)
1. a New-type electric machine winding comprises coil, and described coil is formed by the lead coiling, it is characterized in that: described lead comprises the aluminium core and is coated on copper layer outside the described aluminium core.
2. New-type electric machine winding as claimed in claim 1 is characterized in that: described copper layer also is coated with insulating barrier outward.
3. New-type electric machine winding as claimed in claim 1 or 2 is characterized in that: the cross section of described lead is a pancake.
4. New-type electric machine winding as claimed in claim 1 or 2 is characterized in that: the cross section of described lead is for circular.
