Today, July 10th, marks 170 years since the birth of Nikola Tesla (1856–2026 anniversary).

At Matris, we've spent the past 21 years rewinding stators, refurbishing industrial electric motors, and working daily with the physics he gave us: rotating magnetic fields, AC induction, and the coil and magnet principles that still define every electric motor in factories and on the road today.

His forward-thinking inspired us to develop axial-flux motors for industrial applications, which we now produce in-house.

Every winding pattern we lay down, every rotor we balance, every drive unit we bring back to spec traces back to work he did over a century ago. It's easy to take AC motor theory for granted when it's your daily craft — days like this are a good reminder not to.

Happy birthday, Nikola Tesla.

Summer is in full swing 🌞 — here's something to read for anyone curious about axial flux motors and what we discovered about their industrial potential at this year's Hannover Messe.

"Thanks for your support. For the last 5 years, we struggled a lot to repair this head. Because of your support, we finally did this. Please convey my regards to the whole Matris team!"

That message came from Macro Precision Components (macroprecision.com), a precision CNC machining and fabrication company supplying aerospace and defence organisations in India — and it's the kind of feedback that stays with you.

The story behind it: our partners at Spinex Kft. (spinex.eu) from Hungary, specialists in CNC spindle repair, approached us with a problem nobody had been able to solve. Their client had a critical CNC machine with failed torque motors — and no viable repair solution for their needs.

We took it on from scratch. Two torque motors, built entirely in-house: technical analysis, stator winding, magnet assembly, rotor construction, and epoxy potting. Finally, we did in-house testing to ensure performance will meet Macro Precision's requirements. No shortcuts, no compromises on a machine that operates in aerospace tolerances.

This kind of work is only possible because of what we've built at Matris in Slovenia over the last 20 years — the engineering knowledge, the in-house capabilities.

We're confident the motors will serve them well. 💜

Our work was on display at Tesla Takeover Europe this weekend in Flachau, Salzburg — Europe's biggest Tesla owners event.

Our customer ST-Performance from Salzburg was exhibiting their solutions to the Tesla community, including our LDU stator rewinding service.

As OEM replacement parts become harder to source, solutions like this matter more and more. A properly rewound stator isn't a compromise — it's a better-protected unit than the original, built to last.

Compatible with Tesla Model S (2012–2020), Tesla Model X (2016–2021) and Mercedes-Benz B-Class Electric Drive (B250e).

Thank you ST-Performance for the trust and the great representation. 🤝

Industrial gearboxes rarely fail suddenly. It usually starts with something small — a faint noise, a slight oil leak, a temperature that's just a little higher than normal. By the time it becomes a production stop, the damage has often been building for months.
At Matris, we specialise in repair and overhaul of industrial gearboxes — units paired with servo motors, AC drives, and other industrial drives, across all manufacturers and applications.
Beyond standard overhauls, we regularly handle cases where original spare parts are no longer available. When a machine has been discontinued and components can't be sourced anywhere, we measure the worn parts, create a 3D model and machine new ones in-house on our 5-axis CNC milling centre.

Standard overhaul: within 1 week.
Custom part manufacturing: 5–6 weeks.
12-month warranty on all work.

Shipping worldwide from Slovenia.

If you have a gearbox that needs attention, send us a message.

Woodworking spindle motors run in some of the toughest conditions imaginable — fine dust, resin buildup, moisture, and constant vibration, all while spinning at up to 24,000 RPM.

When a spindle starts to show signs of trouble — unusual noise, vibration, inconsistent surface quality — it's usually been degrading for a while already. The longer it runs in that state, the more damage builds up inside.

Proper spindle servicing isn't just a bearing swap. It means precise tolerance measurements, correct bearing preload, rotor balancing before and after assembly, winding impregnation to protect against the woodworking environment, and a controlled bearing run-in before the motor goes back into production.

Done right, a serviced spindle motor performs like new and stays that way. Done wrong, it's back in the workshop within months.
If your woodworking spindle is due for a service — or already showing signs of wear — get in touch. We'll take it from there.

Iščemo sodelavca v previjalnem oddelku.
Ne zaposlenega. Sodelavca.
Razlika ni majhna.
V Matrisu smo majhen kolektiv, kjer vsak ve, da je od njega odvisno ali bo stranka pravočasno dobila motor nazaj v pogon. Kjer se zjutraj pozdravimo po imenu. Kjer napake priznavamo odkrito in se iz njih skupaj učimo.
Iščemo nekoga, ki: — razume, da je kakovost odnos, ne samo tehnični standard — se ne boji vprašati, ko ne ve — pride po vsem tem še vedno rad v službo
Predznanje v previjalništvu je prednost. Volja do učenja je obvezna.
Kar ponujamo ni le plača. Je ekipa, ki te obravnava kot človeka. Je podjetje, ki v regiji velja za referenčno ime, in ki se vse bolj uveljavlja tudi na svetovnem trgu.
Če te to nagovori — zapiši v komentar ali nam pošlji sporočilo direktno.

P.S: Slika kot referenca, me je AI res navdušil. :)

The EV repair industry is growing fast — and the problems workshops are facing are getting more specific.

A customer from the UK needed a coolant delete solution for their Tesla LDU application, tailored to their exact requirements. So we did what we do — got on a call, understood the problem, and machined it ourselves.

50 custom aluminium parts. First batch. Entirely designed and produced in-house.

This is where our stator rewinding expertise pays off beyond the winding room. Because we rewind Tesla LDU motors for a living, we understand them from the inside out. That knowledge feeds directly into how we design and manufacture supporting components.

The EV aftermarket is still young. But the demand for real, engineered repair solutions is already here.

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.
