A new approach to the prime mover for electric power generation.
Remora™ is Vellox’s patented electromagnetic prime mover, designed to rotate the shaft of an electric power generator.
Hydroelectric systems use moving water, wind systems use wind, and conventional plants use steam or combustion. Remora™ provides that rotation electromagnetically, combining brushless-motor principles with a flywheel that also acts as an induction rotor. Contactless torque and RPM sensors, a dedicated CPU and an integrated Li-ion battery system provide self-start, monitoring and remote control.
Coupled to an electric generator, Remora™ forms SpinG™ — Spinning Generator.
REMORA™ IS NOT A PERPETUAL-MOTION DEVICE.

Remora™ is designed to maintain controlled torque and rotational speed as a remotely controlled prime mover for an electric power generator.

PHASE 04
Because Remora™ RPM is remotely controlled, the rotational speed of the coupled generator shaft can also be controlled. Remora can be programmed to maintain the generator manufacturer’s specified operating RPM or adjust within the permitted operating range in response to electricity demand.

As the Remora™ rotor accelerates, kinetic energy is stored in the flywheel. The architecture is designed to recover a portion of the electrical energy induced by the rotating permanent-magnet flywheel and route it through the power-management system to the onboard battery. A mechanical torque converter on the generator shaft helps manage changing torque and RPM requirements between Remora™ and the generator, with the objective of reducing battery recharge demand.
Net system performance, recharge rate and operating duration remain subject to industrial prototype testing under representative generator loads.
The graph illustrates the designed relationship between increasing rotor speed and battery-charging response during operation. Performance will be quantified during industrial prototype testing.
The relationship between flywheel speed and stored rotational energy is expressed as:
Where I is the flywheel’s moment of inertia and ω is angular velocity. The energy stored in a given flywheel therefore increases with the square of rotational speed, not simply in direct proportion to RPM.
Permanent magnets are integrated into the rotating flywheel, and electromagnetic coils into the stationary stator layer. As the flywheel turns, the magnets pass the coils and induce an electrical output, which is managed by the Remora™ CPU-controlled power architecture.
The graph illustrates the operating transition from high generator-shaft starting torque to progressively lower running torque as RPM increases—the operating region in which flywheel rotational speed and the associated electromagnetic induction also increase.
Remora™ is designed to self-start, establish the required starting torque and maintain controlled rotational speed while driving an electric power generator.
The innovation is focused on the prime-mover side of electricity production. Vellox does not need to reinvent the generator, potentially allowing proven commercial generators to be integrated into remotely controlled SpinG™ power systems.
Vellox’s development of the technology underlying Remora™ dates to its first patent in the Netherlands in 2016. Related flywheel energy-recovery principles were subsequently investigated independently in academic research. A 2022 study by researchers at Sri Ramakrishna Engineering College used MATLAB/Simulink to evaluate a flywheel-based motor-generator architecture, including rotational energy storage, battery charging, energy feedback, and speed/torque behavior. The research was independent of Vellox and did not evaluate Remora™ itself but provides an additional academic reference for several underlying engineering principles incorporated in Vellox’s earlier patented technology.

Remora™ is protected by intellectual property developed and maintained by Vellox, with patent protection originating in the Netherlands and extending through subsequent U.S. patent filings and developments.
Remora™ is the prime mover at the center of the SpinG™ architecture, providing controlled mechanical rotation to a conventional electric power generator.
