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 👇

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 20–30% 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.

NAFTech target a magnet-free traction motor.

No rare earth magnets inside.

Rare earth magnets give high torque density.

Axial flux motors already achieve this.

They are compact and efficient.

Pros of axial flux motors:

High torque density.

Short axial length packaging.

Cons I see:

Heavy rare earth dependence.

Complex cooling and manufacturing.

Now comes SynRM.

Synchronous Reluctance Machine.

Torque from magnetic reluctance difference.

So what is AF-SynRM?

Axial flux synchronous reluctance motor.

It mixes both advantages.

Axial compactness plus magnet-free design.

Radial SynRM avoids magnets.

But needs more installation space.

NAFTech proposes axial SynRM.

Magnet-free motors can reduce dependency

Combine compactness with a magnet-free design.

Less exposure to volatile magnet prices. 🌍

As someone in motor development,

This direction feels practical.

For countries like India, reducing dependence

On imported rare-earth magnets could become

A strategic advantage for the EV ecosystem.

This is one reason I find

Synchronous reluctance motor

technologies are increasingly interesting.

At DriveCore Emobility Systems Private Limited,

Our focus includes PM-assisted-

Synchronous reluctance motors,

Where the goal Is to use magnets-@

More effectively while maintaining

Strong motor performance.

If AF SynRM matches torque density,

will PMSM still dominate EV traction?

Where will AF-SynRM fit first?

 Two-wheelers? Commercial EVs?
