aluminum winding wire,

Enameled wire is widely used in winding wires of motors, transformers, inductors, generators, electromagnets, and coils.
In the past, the diameter range of enameled wire usually required was 0.2-2.0mm [AWG12-32], but nowadays, thinner (diameter less than 0.18mm, AWG33) and thicker (diameter greater than 3.0mm, AWG9) are required on the market Enameled wire.

The enameled wire paint coats up to 30 layers of copper and aluminum wires to provide electrical insulation and help avoid short circuits in the coil. Such enameled wire paint must also have excellent chemical resistance and high temperature resistance, must have excellent adhesion with copper or aluminum wires, and also have excellent mechanical stability.
In some cases, such as for motors driven by frequency converters, a suitable insulation layer should be able to resist partial discharges that may cause short circuits and malfunctions in the engine.

As one of the core three-electric systems of new energy vehicles, electric motors account for 5-10% of the value of the entire vehicle. Among the top 15 new energy vehicle sales in the first half of 2021, the penetration rate of flat wire motors has increased significantly to 27%. The industry predicts that in 2025, the proportion of flat wires in the drive motors of new energy vehicles will exceed 80%.

The motor generally includes a stator and a rotor, with a core and windings on the stator or rotor.
The insulated wire is winded by a certain shape to form a coil. The coil can be a turn or a plurality of turns. A plurality of coils form a group of units and is called a coil group. A combination of a plurality of coils or coil groups constituting one phase or the entire electromagnetic circuit becomes a winding .
