Real Case: How a Turkish Elevator Manufacturer Avoided Export Delays — Without Sacrificing Performance
The Problem
A Turkish elevator OEM was using N42UH (180°C) for their gearless traction motor rotors.
Then April 2025 hit.
China’s export controls kicked in — and their shipments were suddenly on hold, waiting for MOFCOM approval.
No timeline.
No guarantee.
Production schedule at risk.
What Most Suppliers Would Do
Tell the customer to “wait for approval.”
Or keep pushing the same grade — and pass the risk downstream.
What We Did Instead
We looked at the real operating data.
Result?
Even at full load, rotor temperature stayed below 160°C.
Which means:
👉 The 180°C grade was unnecessary
👉 The customer was paying for performance they didn’t actually use
👉 And worse — exposing themselves to export risk for no reason
Our Solution
We recommended switching to N42SHT (160°C, Dy/Tb-free)
Same working performance.
But with a critical difference:
✔ No export license required
✔ No MOFCOM uncertainty
✔ Stable, predictable supply
| Parameter | N42UH (Previous) | N42SHT (XHMAG) |
|---|---|---|
| Max operating temp | 180°C | 160°C |
| Remanence Br | 1270–1310 mT | 1280–1320 mT |
| Coercivity Hcj (min) | ≥ 1990 kA/m | ≥ 1592 kA/m |
| Contains Dy/Tb | Yes | No |
| Export permit required | Yes (12+ weeks) | Not required |
| Lead time from deposit | 12+ weeks | 25–30 days |
| Per-shipment QC docs | — | Magnetic + CMM + Salt spray |
The Outcome
After reviewing BH curves and temperature coefficients, the customer approved the change.
Production restarted immediately.
✅ First shipment delivered in 25 working days
✅ Zero licensing process
✅ Zero customs delays
✅ Zero performance loss
The motor performed exactly the same —
but the supply chain risk was completely removed.
What This Means for You
If you’re still using high-grade NdFeB like UH/EH just “to be safe,”
you might be doing the same thing:
→ Over-specifying
→ Overpaying
→ And unknowingly putting your supply at risk
We help you match the right grade to the real working condition —
so you get performance and supply security.
