Should you design custom axial flux motors yourself? Explore the R&D risks and learn how Beyond Motors' AXM series offers faster, lower-risk customization.
For many CTOs and lead engineers, the allure of "in-house" development is strong. The promise of full IP control and a motor perfectly tailored to a specific chassis or airframe can be tempting. However, when dealing with the extreme physics of axial flux motor architecture, the "Do It Yourself" (DIY) path often collides with significant R&D bottlenecks, thermal management hurdles, and manufacturing complexities.
At Beyond Motors, we’ve moved the goalposts. We offer a middle ground: a collaborative engineering partnership that gives you the customization of an in-house build with the proven, record-breaking performance of our existing AXM platform.
Designing an axial flux motor isn't just about changing the dimensions of a radial machine. Because the magnetic flux travels parallel to the axis, the mechanical stresses on the rotor and stator are fundamentally different.
In an axial flux motor, the attraction forces between the rotor and stator are immense. Maintaining a consistent, sub-millimeter air gap across a large diameter—especially under the high centrifugal forces of electric propulsion—requires specialized bearing selections and housing stiffness.
One of the most common pitfalls in DIY design is underestimating the thermal load during continuous operation. As we analyzed in our Axial Flux Motor Performance and Efficiency Showdown, improper cooling paths can lead to rapid demagnetization. Beyond Motors solves this with a patent-pending water-cooling system already integrated into our base models, saving your team months of CFD (Computational Fluid Dynamics) validation.
In the past, engineers had to choose between a standard off-the-shelf motor or a multi-year custom development cycle. We have introduced a third option: Parametric Modular Customization.
By using a fully parametric model build-up, we can take your specific constraints—voltage limits, peak current, and space envelope—and adapt our AXM architecture to fit. This approach allows you to achieve the 30-40% higher torque density inherent to axial flux without the risk of an unproven design.
When you attempt to design a motor yourself, the prototype phase is where budgets go to die. Every iteration requires new tooling and testing.
At Beyond Motors, we leverage advanced FEM (Finite Element Method) simulations and electromagnetic analysis to refine your custom motor before a single piece of metal is cut. This is why we can move from a customized motor request to the delivery of the first prototype in less than two months.
By choosing our platform, you are building on a foundation that is already a game-changer for high-performance electric vehicles.
For a technical founder, the decision to "build" must be justified by more than just curiosity; it must provide a superior ROI.
Integrating a proven Axial Motor solution for electric mobility reduces your time-to-market and ensures your engineering team can focus on what they do best: the vehicle-level integration.
The era of "building the motor yourself" is being replaced by the era of precision integration. If your project demands custom specs, sizing, or specific project requirements, let our team provide the electromagnetic backbone so you can focus on the mission.
