Enameled Flat Aluminum Wire

New energy vehicle enamelled flat aluminum wire

What Is Enameled Flat Aluminum Wire?: Enameled flat aluminum wire for EV drive motors is a rectangular aluminum magnet wire with an insulating enamel coating. It is designed for electric motor windings, generators, inverters and other electromagnetic equipment that requires controlled conductor dimensions.; The rectangular conductor shape improves space utilization inside a winding slot. Compared with round wire, flat aluminum winding wire can provide a larger conductor area within a similar slot profile. This design helps engineers manage winding geometry, current density, insulation clearance and thermal performance.; LP supplies enamel insulated aluminum wire for new energy vehicle motors and industrial electrical equipment. The final conductor size, enamel system and thermal class are selected according to the winding design and applicable product specification.

Production Characteristics

1. Efficient slot utilization: The rectangular conductor profile supports compact winding arrangements and improved use of available slot space.
2.Reduced conductor mass: Aluminum has lower density than copper, which can reduce winding weight when the conductor design meets the required electrical performance.
3, The paint film has good flexibility and adhesion, which is suitable for coil forming processing.
4. For inverter-fed EV drive motors, partial discharge inception voltage (PDIV), corona endurance and compatibility with the specified cooling oil must be validated for the selected insulation system and operating conditions.
Flexible winding design: Thickness and width can be selected to match slot geometry, insulation clearance and winding architecture.
Intelligent on-line monitoring equipment. LP can review conductor dimensions, enamel build, thermal class, winding process and packaging requirements for electric vehicle motor projects.
