Introduction
New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. Including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. But no matter what type of new energy vehicle, its motor as a power drive is one of the key components. The operation characteristics of the motor as the power of the car are that the power changes quickly and frequently, and the ambient temperature changes greatly. Therefore, it is required to run stably, with strong overload capacity, light weight, good temperature performance and electrical performance.
The winding as the main part of the motor has an important impact on the performance of the motor. Usually, the motor winding uses enamelled copper or enamelled aluminum wire for new energy vehicle motors. The enamelled copper wire is expensive and the processing technology is complicated. Paint, the processing cost is high, and the shielding effect is not very good, it is not resistant to partial discharge, and the corona resistance is not ideal.
New energy vehicles generally use enamelled aluminum wires.
Why choose enamelled aluminum wire?
As we all know, enameled wire is a main variety of winding wire.
Enameled wire is also called electromagnetic wire. It is generally composed of conductor and insulating layer. The bare wire is annealed and softened, and then painted and baked many times. Affected by raw material quality, process parameters, production equipment, environment and other factors, the quality characteristics of various enameled wires are different.
As the heart of new energy vehicles, there are many electromagnetic wires in the drive motor. If the electromagnetic wire and insulating material cannot withstand the high voltage, high temperature, and high voltage change rate during the operation of the motor, they will be easily broken down and reduce the service life of the motor. At present, when most enterprises produce enameled wires for drive motors of new energy vehicles, due to the simple process and single paint film, the products produced have poor corona resistance and poor thermal shock resistance, which affects the service life of drive motors.
Enamelled aluminum wires for new energy vehicle motors have excellent high temperature resistance, mechanical properties, electrical properties and chemical properties, and excellent freezing resistance. However, the existing enamelled aluminum wires for new energy vehicle motors must include Among the four major properties of mechanical properties, chemical properties, electrical properties and thermal properties, the mechanical properties and electrical properties in some cases still need to be improved and improved. For example, in terms of shaping, due to its flexibility and insufficient rigidity, the winding shaping is not so arbitrary. And in terms of electrical conductivity, under certain usage conditions, its load may be relatively weak, making it difficult to meet certain usage requirements. In addition, its solderability is relatively poor, which brings inconvenience to the connection to a certain extent.
Enamelled aluminum wires for new energy vehicle motors have good solderability and do not require special treatment like aluminum wires; they also maintain the advantages of light weight aluminum wires, which are very effective in reducing the weight of windings or coils; more importantly, The electrical properties of enamelled aluminum wires for new energy vehicle motors are optimized. The same wire cross-sectional area has higher load capacity, and its paint layer has significant oil resistance and temperature resistance characteristics, which relatively improves the output power of electrical appliances under the same circumstances. , effectively reducing the production cost, and its corona resistance is better, which can prolong the service life of the motor.
So, if you are engaged in new energy vehicles and want to know about enamelled aluminum wire, welcome to Lanpu website. We will bring you the best quality and most suitable enamelled aluminum wire.
