Imagine a world where the hum of electric vehicles is powered by ingenuity, not by rare earth minerals. That's precisely the future Astemo, the joint venture between Hitachi and Honda, is actively building. They've unveiled a groundbreaking new motor for pure electric vehicles, and the most exciting part? It's completely free of rare earth materials.
For a while now, the go-to for electric cars has been the permanent magnet synchronous motor, often shortened to PMSM. These are fantastic, offering high power density which means smaller, lighter powertrains, and they're incredibly efficient, squeezing more miles out of every charge. But there's a catch, and it's a significant one. The magnets embedded in these motors, the ones that give them their punch, often rely on elements like neodymium. These are rare earth elements, and their reliance creates a couple of big headaches: higher costs and a dependency on a few key global suppliers. It’s a supply chain vulnerability that many in the industry are keen to sidestep.
This is where Astemo's innovation shines. Their new motor is based on a synchronous reluctance motor system. While it’s not quite ready for mass production – we're looking at a target of around 2030 for practical application – the potential is immense. By ditching the rare earths, Astemo is paving the way for electric vehicles that are not only more sustainable in their operation but also potentially more affordable and less susceptible to global supply chain fluctuations.
Looking at Astemo's broader strategy, it's clear they're deeply invested in the automotive industry's transformation. Their business is structured around key areas like Powertrain & Safety Systems, Chassis, and Motorcycles. In the Powertrain and Safety sector, they're leveraging their expertise in inverters and motors to develop highly efficient electric axles, integrating gearboxes for optimal performance. They're also pushing forward with autonomous driving technologies, focusing on sensing systems like stereo cameras and the crucial electronic control units and software that make it all work.
The Chassis division is equally impressive, bringing together electronic and electric brakes, suspension, and steering systems. The real magic here is in their integrated control, offering sophisticated solutions for next-generation mobility. And in the motorcycle world, where they hold a leading global share, they're applying these advanced technologies to create integrated systems for powertrains, suspension, and brakes, especially for the growing EV market in Asia.
Astemo's vision extends beyond just hardware. They're embracing the concept of the software-defined vehicle, using platforms like Lumada to develop advanced in-car software and Over-the-Air (OTA) update capabilities. This means vehicles can evolve and improve over time, a truly exciting prospect.
The automotive landscape is undergoing a seismic shift, driven by the push for carbon neutrality and the rise of CASE (Connected, Autonomous, Shared, Electric). Astemo is strategically positioned to thrive in this new era. They're investing heavily in R&D, particularly in xEV-related products like motors and inverters, and are also strengthening their software development capabilities. Their goal is to contribute to a better planet through 'green' value – reducing emissions with their electric technologies – and to enhance people's lives through 'social' value – improving safety and comfort with advanced driving assistance and chassis systems.
It's a complex dance of technology, sustainability, and market demand, and Astemo seems to be leading the choreography. Their commitment to developing rare-earth-free motors isn't just a technical achievement; it's a significant step towards a more resilient, accessible, and environmentally conscious future for electric mobility. It’s a story of innovation that feels both deeply technical and remarkably human, aiming to make our journeys better for us and for the planet.
