Description
Technical field
The utility model relates to machine windings.
Background technique
With universal, the improvement of performance needs and promotion of motor of motor application, to improve power density and efficiency etc.,
Conventional motor is combined using the round wire of a plurality of thin circular section, turns to winding, then under in motor slot, due to round wire
Between heat transfer it is difficult, and when mutually arranged, there is biggish gaps between round wire, therefore, current developing direction
It is that circular section conducting wire is replaced by the conducting wire (abbreviation flat wire) of rectangle using section, still, the flat wire coiling used is difficult, technique
Property is poor.
By taking the patented technology of Remy Inc., the U.S. as an example, the technology is firstly the need of the u-shaped conductor 5 that flat wire is made to hairpin-type
Then U-shaped conductor is arranged successively in insertion winding slot of core by (as shown in Figure 1), later, referring to fig. 2,3, then by u-shaped conductor
Wire termination is to U-shaped two lateral bend, and two U-shaped wire terminations of formation are opposite two-by-two, later welding opposed end, shape
At machine winding.Hair pin type structure used in the structure and technique, the complex forming technology of conducting wire, and when insertion motor,
Due to being (one one end is below another) mutually laminated between conducting wire, either of which cannot be inserted once
Enter, complex process, it is difficult to realize automated production, even if realizing, the cost of equipment is also very high, while production efficiency is low.
In addition, the dogleg section of the U-shaped conducting wire of the prior art had both needed circular arc type part due in actual production,
Part is offset, also to there is a sloping portion, complex forming technology, production efficiency is low.Meanwhile the conducting wire after iron core with lead
It needs that insulating materials is arranged between line, to meet insulating requirements, the use of insulating materials increases the flowing of conducting wire surrounding fluid
