The technology of the Motor Notatus redefines the limits of power density and volumetric efficiency in hydraulic actuators and motive power units. Its patented architecture offers decisive competitive advantages over conventional hydraulics and heat engines.
1. Key Operational Advantages
- High-Efficiency Closed-Loop System (91.6% Reuse): As there is no chemical degradation or combustion, the same batch of hydraulic fluid is reused indefinitely in a closed-loop system, requiring an external supply of just 8.4% per drive cycle.
- Reduction in Pumping Demand (Factor K = 9.16): Internal volumetric amplification makes it possible to use notably more compact and lower-consumption feed pumps to obtain the same hydrostatic thrust on the cylinder head.
- Total Anaerobic Operation: The system operates without an air intake or the expulsion of reactive or exhaust gases, enabling its airtight containment in extreme or oxygen-free environments.
- Assisted Transient Start: Integration of a high-response hydropneumatic accumulator to absorb starting inertia without overloading the primary network or the feed pump.
- Scalability and Modularity: Design adaptable to multiple modules coupled to a common crankshaft, scalable for both micro-generation and large industrial plants.
2. Industrial Application Fields
- Range Extenders for Electric Mobility (REEV / E-Mobility): Continuous high-density auxiliary generation for battery recharging while on the move or stationary with minimal onboard mass.
- Marine and Submarine Propulsion: Anaerobic operation with no gas emission or bubble generation, ideal for submersibles, ROVs and critical sealing environments.
- Stationary Generation and Microgrids: Backup plant and continuous supply in isolated or remote facilities with minimal maintenance and long fluid operating life.
- Aerospace and Confined Space Systems: Reliable mechanical power generation in a closed cycle, independent of the external atmosphere.
