While the "all-electric" transition is the long-term goal, the immediate reality for many CTOs in the automotive and nautical sectors is the demand for high-performance hybridization. Combining an Internal Combustion Engine (ICE) with the right electric machine is a delicate balancing act of weight, packaging, and power density.
At Beyond Motors, we are seeing a massive shift in hybrid architecture design. The traditional radial motor is often too bulky to fit into a hybrid transmission without significant vehicle redesign. The axial flux motor, however, is the "missing link" that allows for a seamless, high-torque hybrid integration without the massive footprint.
In a P2 hybrid configuration—where the electric motor is placed between the ICE and the transmission—space is at a premium. Every millimeter added to the powertrain’s length requires adjustments to the chassis, suspension, or cabin volume.
The disc-like, "pancake" geometry of an axial flux machine is the perfect solution for this bottleneck. By utilizing the Beyond Motors AXM series, engineers can integrate a high-output motor into a space that would be physically impossible for a radial machine.
The primary engineering goal of hybridization is often "torque filling"—using the electric motor to provide instant torque during the ICE's turbo-lag or gear-shift intervals.
Because an axial flux motor offers 30-40% higher torque density than radial designs, it provides the necessary "punch" to significantly improve vehicle dynamics. The high torque density of our AXM4, for instance, provides up to 950 Nm of peak torque, allowing a smaller, more efficient ICE to perform like a much larger displacement engine. This isn't just about speed; it's about optimizing the engine’s operating map for better fuel economy and lower emissions.
Hybrid powertrains are notoriously difficult to cool. Heat from the ICE can soak into the electric motor, and the confined packaging of a hybrid module limits airflow.
We have addressed this with our patent-pending water cooling system. Unlike air-cooled units that suffer from thermal derating in cramped engine bays, our high-performance e-motors utilize a direct-to-winding cooling path. This ensures that the motor can handle sustained regenerative braking or heavy-load boost cycles without losing efficiency. This thermal stability is a core reason why our technology is considered the leading solution for electric and hybrid mobility.
Whether you are designing a 48V mild-hybrid for a luxury SUV or a 800V high-performance system for a racing vessel, the motor must be adaptable.
The Beyond Motors AXM series is designed with modularity in mind. Our stackable architecture allows engineers to scale the electric portion of the hybrid powertrain by "stacking" rotors to meet specific torque targets. This flexibility allows for:
The era of choosing between a bulky hybrid or a low-power one is over. By pairing a modern ICE with axial flux technology, you achieve a powertrain that is lighter, more responsive, and easier to package. For a CTO, this translates to reduced R&D costs and a faster time-to-market for electrified platforms.
