Application of ultra-fine polyurethane enameled copper round wire in consumer electronics micro motors

Focusing on the demand for miniaturization in consumer electronics, the ultra-fine polyurethane enameled copper round wire used has a minimum wire diameter of 0.015mm, perfectly adapting to the compact structural design of micro motors. In the vibration motor of a mobile phone, its fine diameter characteristic allows the coil to tightly wrap and generate a stable magnetic field to drive the vibration of the oscillator after being powered on.

At the same time, the direct welding can simplify the connection process between the motor and the mobile phone motherboard; When used for laptop fan motors, its temperature resistance of 130-155 ℃ can cope with the heat generated by long-term operation of the fan and avoid insulation layer aging. This type of enameled wire also has self-adhesive function and is suitable for the skeleton free winding process of drone motors. It not only provides matching for consumer electronics products of enterprises such as Xiaomi and DJI, but also improves the welding efficiency of related micro devices by more than 30%, significantly reducing the production time of electronic manufacturers.
