While electrical vehicles (EV) drive sustainable mobility, their driving range and charging time remains restricted by traditional technologies. Until now. Meet Ampact™, our PEEK insulated copper magnet wire designed for stators in high-voltage e-motors (800V and beyond). Whether you go for hairpin or other types of wave winding, Ampact™ helps you to secure the extra mile while saving design and assembly time, energy and valuable resources.
High-voltage drivetrains demand higher chemical, thermal, electrical, and mechanical capacities of the magnet wire used in the stator of the e-motor. To meet these new requirements and extend the lifetime of the copper winding wire, we replaced the traditional insulation with an innovative polyetheretherketone or PEEK-coating. The thin coating (100-200µm on average) is applied in one extrusion step using a single layer, which helps you save plenty of time during the production process. Additionally, the extruded coating …
We help you shift to the next gear of both innovation and sustainability. Ampact™ winding wire is built not only to perform in extreme motor environments. Also during the production and end-of-life recycle process it has strong credentials.
Firstly, unlike the multi-step application process of conventional enamel coatings, the PEEK coating is applied in one single step and therefore significantly more energy-efficient.
Next, the coating process is solvent-free. By eliminating harmful solvents, we put the brakes on NOx gasses associated with enamel coatings. PEEK coating also offers excellent end-of-life recyclability thanks to its thermoplastic characteristics. Additionally, because of PEEK's higher insulation power you need less insulation material. All of this contributes towards reducing the total carbon footprint.
Choosing a Bekaert product from the inhera® range of selected sustainable solutions — like Ampact® magnet wire — helps you and your customers achieve sustainability goals faster.
Ampact® magnet wire combines performance with a lower environmental footprint. Thanks to its high-performance PEEK insulation, Ampact® enables 10% lower direct CO₂ emissions and eliminates the use of harmful solvents in production.
This thermoplastic coating not only boosts motor and EV efficiency — delivering more range from the same battery — it can also be cleanly separated from the copper at end-of-life, supporting full recyclability.
Selecting Ampact™ assures you of a responsible choice and helps you meet your sustainability targets faster.
Note: References such as lifecycle emission savings are based on specific assessments and assumptions. Actual results may vary depending on application, usage conditions, and other influencing factors.
Without affecting the wire's conductivity, Ampact™ PEEK-insulated magnet wire allows you to make sharper and shorter bends which saves space. Because of the high insulation power of the PEEK-coating, the wire thickness can be made thinner. This not only saves on the cost of copper, but it also allows you to make the stator smaller and lighter which in turn leads to lower cost.
So, as an OEM you can have the best of both worlds:
Bekaert is an established global supplier of solutions for the automotive market. Because of our global footprint we are able to install capacity worldwide and adhere to all the quality labels and standards (IATF, IEC, etc.).
