Modular Clean Power Systems Meticulously engineered meeting the efficiency demands of today’s energy economy
HaloDrive is OE’s patented axial flux motor-generator-pump (MPG) that combines unmatched efficiency with industry transforming pricing, performance and configurability.
HaloDrive utilizes a breakthrough modular, tunable permanent-magnet machine architecture to deliver MGPs that are slimmer, lighter, more cost-effective, and delivers up to 30–40% higher power density than conventional motor-generator-pump systems.
The platform offers unmatched configurability—powering BEV and PHEV passenger vehicles, commercial fleets andd eTRUs, marine systems, and aerospace platforms—while also significantly improving efficiency in stationary industrial applications such as data centers and mining operations.
HaloDrive is an advanced motor-generator-pump designed to power anything that moves or to move anything that needs power.
Applications:
High-torque drive motor: compact and powerful for passenger EVs or in-wheel commercial vehicle propulsion.
Regenerative generator: mounted on truck axles or trailers to harvest kinetic energy or power refrigeration systems.
Precision impeller pump: integrated into thermal management systems in data centers.
Superior Torque Density and Power
Designed for environments where space and thermal efficiency are at a premium, HaloDrive delivers remarkable torque and power within an ultra-compact envelope — unlocking new possibilities for integration across mobile, stationary, and industrial platforms.
Industry-Leading Efficiency
With peak operational efficiencies reaching up to ~97%, HaloDrive is engineered to minimize conversion losses and substantially reduce electricity waste across a broad range of applications — from mobility systems to grid-connected and industrial solutions.
Modular Versatility
Featuring a compact, modular, and highly adaptable architecture, HaloDrive can be configured for seamless integration across diverse mechanical, electrical, and thermal systems — typically without requiring major structural changes, enabling rapid deployment and flexible scaling.
System Level Cost Advantage
By streamlining integration and improving overall performance, HaloDrive delivers measurable reductions in total system costs — in some deployments approaching 35% compared with traditional electrical architectures.
Strengthening Resource Security and Supply-Chain Resilience
By designing a high-performance motor that requires no rare-earth elements, HaloDrive dramatically reduces exposure to volatile supply chains and strengthens industrial resilience — enabling electrification at scale without geopolitical compromise.
“The US depended on China for 70% of its rare-earth imports from 2020-2023. Even more telling – current estimates suggest 95% of the world’s neodymium is processed in China.”
