Excit3D Max Motors

Rev 2 in stock!

Rev 2 upgrades the wiring from PVC to FEP-insulated wires and leaves the cable ends bare.

Note: Datasheet is still for rev1. Updated one will be added soon. Only change between rev1 and rev2 is the cable type and colors.

The Story Behind Max Motors

About a year ago, one of the mods in our server came to us with a graph and a wild proposition: he had found the best NEMA 17 motors on the market. According to Stanciu's simulations, these motors had better top speed than LDO 2504s and better torque than LDO 2804s — and the comparison to high-tier options like Krakens and Classifieds was even more striking. We had to test the hypothesis.

Stanciu installed them on his 2WD Trident and pulled travel speeds of 1500@50k. Then Goat tracked down more samples from the manufacturer, and Shoey rigged them up on his Boombox extruder. The Max Motors outperformed anything he had used before. It was clear that these NEMA 17s were elite — a cut above the rest.

But there was a problem: the motors were only available with short shafts, and that just wouldn't work for us (we support our shafts here at Excit3D).

We reached out to Shenyang and commissioned the custom long-shaft motors you see here. We also added some extra goodies: Class H high-temperature insulation, aviation-grade grease, and upgraded bearings. We dialed these motors up to the Max.

If you want to get maximum performance from your printer, there's only one way to do it: get yourself some Max Motors.

TMC5160 stepper drivers are recommended to take full advantage of these motors.
