The number of electric vehicles has soared in recent years. According to the Netherlands Enterprise Agency (RVO), by 2024 there were more than 20 times as many electric passenger cars on the road as in 2018. That may not come as a huge surprise – driving electric is more sustainable, and the cars just keep getting better.
One key part of the vehicle – and of that progress – is the electric motor, the beating heart of every electric car. To perform properly, an electric motor relies on a very special type of steel. This steel needs to handle the magnetic forces involved in driving and rotating the motor’s components.
But just how special is that steel – and what does it mean for comfort, range and safety?
Specialised steel makes electric motors more efficient
The aim is to convert as much of the battery’s energy into motion – and as little as possible into heat. Heat in an electric motor is basically wasted energy. Using thinner steel helps reduce this loss. Thanks to the latest innovations, we can now produce steel as thin as 0.2 millimetres – roughly the thickness of a human hair. This ultra-thin steel conducts the magnetic field much more efficiently.
Thinner steel means less energy lost as heat, which translates into a longer driving range. Whether you’re commuting or off on a day trip, you can go further without worrying about your battery. In fact, the latest innovations in electric motors – with steel playing a key role – can enable up to 50% more range on a single charge compared to older motor types.
Thanks to smart steel, quieter motors make for a comfortable drive
The special techniques used to join the thin steel sheets in the motor help reduce vibrations and noise. That also makes the motor more efficient. The result is smoother performance and a much quieter ride compared to older or less advanced motors. For drivers and passengers alike, this means more peace and comfort. No distracting hum or vibrations – just a smooth, relaxed driving experience.
Thinner steel results in less maintenance and less costs
Thinner steel not only helps prevent energy loss, but also keeps the motor cooler while driving. And that has another big advantage: less wear and tear on components, directly contributing to a longer motor lifespan.
A cooler-running motor performs better and stays reliable, even under heavy use. That means fewer maintenance costs and a car you can enjoy for longer – without surprise breakdowns, costly repairs or unnecessary trips to the garage.

The future of steel for electric vehicles is also being shaped in space! Tata Steel Nederland is working with the ISS and the European Space Agency (ESA) to research advanced steel in the International Space Station, 400 kilometres above Earth. These innovations help make electric motors more efficient, quieter and more durable – all contributing to a longer lifespan.
