Alcutrans supplies high-quality enameled copper rectangular wires specially engineered for electric vehicle (EV) motor applications. These rectangular magnet wires provide a superior fill factor due to their excellent stackability, enabling compact and high-efficiency motor designs.

Rectangular conductors are ideal for hairpin and wave winding technologies, supporting automated winding processes and easier coil insertion.

Performance Advantages

Due to the higher copper content within the same slot area, enameled copper rectangular wires deliver higher power density, enabling EV motors to achieve the peak power required for traction applications.

The increased surface area of rectangular wires enhances heat dissipation, ensuring better thermal management under high-load conditions. Additionally, their larger cross-sectional area results in lower electrical resistance, significantly reducing copper losses compared to round wires.

Supported Motor Types

Alcutrans enameled copper rectangular wires are suitable for:

• Permanent Magnet Synchronous Motors (PMSM)
• Induction Motors (IM)
• Brushless DC Motors (BLDC)
• Switched Reluctance Motors (SRM)

Insulation System

Selecting the right insulation is critical for EV motor performance, durability, and reliability. Alcutrans offers insulation systems optimized for thermal endurance, mechanical strength, and long-term electrical stability, ensuring reliable operation in demanding EV environments.
