Modified polyester enameled copper wire belongs to Class F and is widely used in the windings of Class B and Class F motors. It has good mechanical properties and high heat resistance, and can be wound with a high-speed winding machine. However, the heat resistance, impact resistance, and moisture resistance of polyester enameled copper wire are poor.
