I often look at torque density numbers.But the real engineering challenge may be - Achieving them without magnets.
This rare-earth-free Axial SynRM looks practical š We know that High torque needs rare earths. In my motor development experience, Material cost always becomes a bottleneck. For many EV manufacturers, Reducing motor cost is becoming As important as increasing efficiency. A motor that uses fewer critical materials could improve both profitability and supply chain stability. I was reading about the NAFTech project. Typical PMSM uses 20ā30% magnet cost. Their SynRM reduces thi

We know that High torque needs rare earths - What if we remove them completely?
We know that High torque needs rare earths What if we remove them completely? Yes, this Axial SynRM looks practical š In my motor development experience, Material cost always becomes a bottleneck. I was reading about the NAFTech project. Typical PMSM uses 20ā30% magnet cost. Their SynRM reduces this to near zero. First, why and what is a rare earth? Like neodymium and dysprosium. They give high magnetic strength. But prices are volatile. Supply chains are concentrated glob
