EI/AIW 180 4.00mm*0.40mm custom rectangular enameled copper wire for motor winding

This custom-made wire 4.00*0.40 is 180°C Polyesterimide copper flat wire. The customer uses this wire on the high-frequency motor. Compared with the enameled round wire, the cross-sectional area of this flat wire has a larger cross-sectional area, and its heat dissipation area is also increased accordingly, and the heat dissipation effect is significantly improved. At the same time, it can greatly improve the "skin effect", thereby reducing the loss of high-frequency motor. Improved efficiency for customers.
