The EV market has a rising problem.
Millions of electric vehicles are quietly rolling out of factory warranty — and manufacturers are not providing sufficient solutions to support them post-warranty.
Charging infrastructure, range anxiety, battery technology — these get all the attention. But for workshop owners and fleet operators managing older EVs, the real headache is finding a specialist who can actually fix a failed drive unit without replacing the entire powertrain at OEM cost.
That's exactly the gap we fill.

We don't service EVs. We remanufacture their hearts.
At Matris, we specialise in the rewinding and servicing of Electric Drive Units (EDU) — the stator is the electrical core of the motor, and it's what we do best.
Since 2023, we've been continuously developing and refining our Tesla LDU rewinding process, serving independent EV workshops, repairers, and specialists across Europe.
Current focus: Tesla Model S (2012–2020) · Tesla Model X (2016–2021) · Mercedes-Benz B250e / B-Class Electric Drive

Every unit we rewind includes:
→ Completely new copper wire — no reuse of existing material, ever
→ New copper nickel-plated phase connectors, dimensioned to OEM spec
→ New NTC 100 kΩ thermistors with green and blue connector cables
→ Full epoxy encapsulation of the entire stator (Tesla's factory version covers only the winding heads)
→ Pre-dispatch testing with Schleich MTC-2 to GΩ insulation standard — vs. Tesla's OEM minimum of 4 MΩ
The result:
✔ 3–5% increase in motor capacity
✔ 3% increase in phase conductor cross-section
✔ Significantly improved heat dissipation
✔ Reduced stator overheating
✔ GΩ-level insulation durability — virtually indestructible

How it works: send us the stator and rotor. We inspect, assess, and send you a quote. Once approved, we rewind and return a unit that outperforms the original. Every job comes with a 2-year warranty.
If you run an EV workshop or deal with Tesla and Mercedes-Benz EV drivetrains — let's talk.
