Can enameled aluminum wirereduce costs? A motor is a mechanism that converts electrical energy into kinetic energy, and its power supply efficiency directly affects mechanical kinetic energy. Therefore, under the consideration of the efficiency of energy conversion and economic cost, enameled copper wire has become the best choice among motors. If only considering cost reduction, choosing enameled aluminum wire to wind the motor coil will not only reduce the material cost, but also reduce the overall weight of the motor, which can greatly improve the competitive advantage of the product. However, the introduction and use of enameled aluminum wire in motors has not been welcomed as expected. It is not only the impact of the deterioration of conductivity, but also the lack of tensile strength of aluminum wire in production, resulting in coil failure. Solid and easy to disconnect. Due to the difference in the material of enameled aluminum wire spot welding, special solder is required for processing. There have been cases of detachment at the welding point due to poor spot welding and the skin effect of the current, and the thermal conductivity of the aluminum wire is also Compared with copper wire, this will make the temperature rise quickly and high temperature inside the motor. Various reasons make the motor gradually reject the enameled aluminum wire.
The motor is not adaptable to enameled aluminum wire (including Rectangular Enameled Aluminum Wire). The enameled copper-clad aluminum wire has become a new generation of high-quality choice. The inner layer has the characteristics of aluminum, which greatly reduces the weight and cost. The outer layer of copper retains the strength and spot weldability of the copper wire. This composite performance greatly improves the acceptance of use, and the copper-clad aluminum wire is formally introduced into the motor industry.
