Beyond Motors AXM3 Axial Flux Motor

The Beyond Motors AXM3 is a water-cooled axial flux motor that makes 260 kW (349 hp) peak and 545 Nm (402 lb-ft) peak torque, in a flat package 340 mm across and about 155 mm long that weighs 28.6 kg (63 lb).

What sets it apart is its continuous rating: 155 kW and 350 Nm, well over half of peak. It keeps making that power on long climbs, track sessions and in heavy vehicles, where many motors have to back off after a short burst. Beyond's patent-pending water-cooling system takes the heat straight out of the stator, so it runs on your vehicle's ordinary glycol coolant loop.

We sell it in one configuration, chosen for 400 V-class EV conversions: • Single stack with the low-voltage winding (400 V DC) • 1×UVW phase configuration with Amphenol EMC IP67 straight phase connectors • Angled cooling pipes • Standard output shaft • RM44SI encoder for rotor position • IP56 protection

It's a motor only. It runs on the NX Technologies R300 controller, which Beyond calibrates to the motor and supplies with its wiring as a plug-and-play package. We sell the controller separately, and both come together in the Current EDU and the Flux Drive System.

The motor bolts directly to the rear of the Behemoth Helix gearboxes, so it fits the same independent-suspension and inline layouts as the other motors in our catalog.

What you'll also need: the NX R300 controller, a gearbox, a coolant loop for the motor and controller, DC cables from your battery, a precharge circuit, and a VCU or other controller to command it.

Notes from the Current EV team

Why we added it: the AXM3 holds its power. Its 155 kW continuous rating is close to the peak rating of many motors we put in cars, so it suits heavier vehicles and builds that will be driven hard for long stretches, not just in short bursts.

Buy it with its controller: Beyond calibrates the NX R300 controller to the motor and supplies the wiring, so the motor and controller arrive set up for each other. You don't need to characterize the motor or align the encoder yourself before the first spin.

Cooling: run the motor and the controller in a water/glycol loop. Plumb the angled cooling pipes before you set the motor's final position, because they sit close to the housing.

Picking a gearbox: the motor bolts straight to the Behemoth Helix IS (E30 or E40) or Helix IL. Tell us your vehicle, tire size and target top speed and we'll recommend a gearbox and ratio.

Lead time and shipping: Beyond Motors builds each motor to order in Slovenia. Shipping is not charged at checkout: after you order, someone from our team will contact you to confirm the lead time and to arrange and quote freight.
