NX Technologies R300 Motor Controller – Plug-and-Play for Beyond AXM3
Couldn't load pickup availability
The NX Technologies R300 is an 800 V-class motor controller from NX Technologies in San Sebastián, Spain, and it's the controller Beyond Motors pairs with the Beyond Motors AXM3 axial flux motor. We sell it as Beyond's plug-and-play package: Beyond calibrates the R300's settings to the AXM3 and supplies it with its wiring, so the motor and controller arrive set up to run together.
The calibration is usually the slowest part of a conversion. A controller paired with a third-party motor has to be characterized and its position sensor aligned before it can make full power. With the plug-and-play package, Beyond has already done that for the motor you're buying.
What's included
- NX R300 controller with settings calibrated to the AXM3 (400 V winding, RM44SI encoder)
- Wiring for the controller and motor, as supplied by Beyond Motors
