Beyond Motors vs. YASA: A Detailed Comparison of Performance, Reliability, and Cost

In the world of high-performance electrification, the debate is no longer between radial and axial flux—it’s about which axial flux architecture wins on the factory floor and in the field. For CTOs and lead engineers, two names often dominate the conversation: YASA and Beyond Motors.

While YASA has built a reputation in the high-end supercar segment (powering the likes of Ferrari and Lamborghini), Beyond Motors is redefining the landscape with a focus on industrial scalability, continuous power, and cost-efficient integration for the automotive, nautical, and UAV sectors.

Here is a technical breakdown of how Beyond Motors stacks up against YASA across the three pillars of powertrain procurement.

‍

1. Performance: Peak Power vs. Continuous Duty

YASA is synonymous with extreme peak power density. Their "Yokeless and Segmented Armature" topology is designed for the explosive bursts of speed required by hypercars. Recently, YASA achieved staggering peak power densities, but this often comes with high complexity in cooling and manufacturing.

At Beyond Motors, our focus is on sustained performance.

• Continuous Power Density: While competitors focus on 10-second peak bursts, our high-performance e-motors are engineered for high continuous loads. Our AXM4 series delivers 230kW of continuous power from a 48kg unit, a feat made possible by our patent-pending water-cooling system.
• Stackability: One of the core differences is modularity. As we detailed in our Axial Flux Motor Performance and Efficiency Showdown, Beyond Motors utilizes a stackable design. Need more torque? You don’t need a new motor; you stack a second or third AXM unit. This allows for a power range reaching up to 1.2MW of peak power.

2. Reliability and Redundancy

In the nautical and aerospace industries, a single point of failure is unacceptable.

• Cooling Philosophy: YASA typically employs direct oil-cooling. While effective, it increases system complexity and the risk of leaks in sensitive environments. Beyond Motors uses a specialized water-glycol cooling jacket that is easier to integrate into existing vehicle cooling loops.
• Winding Redundancy: A key reliability feature of the Beyond Motors AXM series is the Double Winding (2 x UVW) option. This creates two separate electromagnetic halves within a single motor. In the event of a controller or winding failure, the motor continues to operate at half power. This level of "limp-home" redundancy is a critical requirement for CTOs in the marine and UAV sectors, where mid-operation failure is not an option.

3. Cost and Mass-Market Scalability

The "YASA vs. Beyond Motors" debate often comes down to the balance sheet.

• Manufacturing Complexity: YASA’s segmented armature requires high-precision assembly that, until recently, was difficult to scale outside of low-volume supercars.
• Cost-Efficiency: Beyond Motors was founded with the goal of bringing axial flux technology to the mass market. By optimizing our Axial Motor technology for electric mobility, we have reduced the bill of materials (BOM) and simplified the manufacturing process.
• Customization vs. Off-the-Shelf: YASA’s integration often requires deep partnership with Tier-1 OEMs. In contrast, Beyond Motors offers a "plug-and-play" custom solution. Whether you need a customized shaft, specific windings, or a tailored cooling interface, our turnaround time for first motors is typically under two months.

The Verdict for Your Next Project

If you are building a million-dollar hypercar where peak power is the only KPI, YASA remains a formidable choice. However, if your project demands high continuous torque, mission-critical redundancy, and a cost-effective path to mass production, Beyond Motors provides the superior ROI.
