Rotational and Linear Dynamics Driven by Field Interaction.
All electric motors operate using magnetic fields created by the interaction of
magnets — whether permanent or electromagnetic. In the world of electric drives,
nearly all conventional solutions follow the same logic: power is generated by
electromagnets, while permanent magnets serve only a supporting role. This
approach has long become an industry standard — but it comes at a significant
cost: high energy consumption, complex cooling systems, bulky power supplies, and
ultimately, greater operational expenses and lower overall efficiency. Most
manufacturers never question how much electricity your motor will consume. Their
goal is simply to achieve rotation — at any cost.
NIMEC takes a different path. We build our rotary systems on a force freely
available in nature — the field of permanent magnets. Instead of spending
kilowatts to generate torque, we use powerful magnets as the primary source of
motion, and employ electromagnets purely as a control mechanism — pulsing
briefly to initiate and stabilise the cycle.
This approach radically changes the balance between output and energy
consumption. We don’t chase massive currents — we work with the field itself.
And therein lies a fundamental advantage: high power, with record-low energy
usage. When every watt counts, a NIMEC solution becomes not just technically
sound — but economically essential.
NIMEC generation modules are engineered for long-term autonomous operation and
high operational reliability. At the core of the system are 60 cylindrical
permanent magnets, each measuring 100 mm in diameter and 100 mm in height,
manufactured from high-energy NdFeB material, grade N52M. The magnets are
mounted on the end face of two heavy-duty rims, precisely aligned to ensure
maximum stability in magnetic interaction.
Opposite the permanent magnets are electromagnets featuring U-shaped cores made
from high-performance Permendur alloy, with coils wound from 100% copper. The
system is controlled via a controller based on the Arduino Mega 2560, equipped
with a touchscreen LCD display for parameter monitoring and manual input.
Power is supplied by four ultracapacitor modules BMOD0500 P016 B02, rated at
16 V, 500 F, and up to 100 A each. Power switching is handled by solid-state
relays (SSRs) from leading global manufacturers, ensuring precise and reliable
actuation.
The entire assembly is enclosed in an impact-resistant casing made from
non-magnetic material, offering electromagnetic noise suppression and robust
protection from external conditions. Compact, modular, and reliable, NIMEC
systems are ideal for industrial deployment — including in remote or unstable
power environments.
Rotary motors from NIMEC easily handle the drive of powerful industrial
compressors and hydraulic pumps used in the most demanding sectors of industry.
Our solutions successfully integrate with compressors from leading global
manufacturers such as Atlas Copco, Ingersoll Rand, Bauer, and Gardner Denver,
ensuring stable operation at pressures up to 500 bar and flow rates up to 22,000
m³/h.
In hydraulic systems, NIMEC effectively drives pumps from Bosch Rexroth, Parker
Hannifin, and Eaton, which in turn power heavy hydraulic motors like
Sauer-Danfoss, Rexroth A4VSO, and Parker P-Series. This setup allows for high
power output and precise torque control, which is especially important for
complex technological processes and mobile equipment.
Tailoring the system to the specific needs of the customer guarantees an optimal
balance of power, efficiency, and reliability, minimising energy consumption
and maintenance costs. Using NIMEC’s magnetic rotary modules in the drives of
hydraulic pumps and compressors opens new opportunities to enhance efficiency
and reduce operational expenses across a wide range of industries.
NIMEC linear modules are based on controlled interaction between electromagnets
and a powerful permanent magnet, where magnetic energy is efficiently
transformed into linear motion. The basic configuration includes two
electromagnets positioned at the ends of the active zone, with a cylindrical
permanent magnet placed between them. The system operates by applying brief
impulses that reverse the polarity of the electromagnets, forcing the permanent
magnet to move directionally along a predefined axis.
During this linear motion, a portion of the permanent magnet’s magnetic energy
is converted into mechanical work. In each cycle, at least 25% of the full
magnetic field potential is effectively utilised — a substantial value given
the physical nature of magnetic interaction. This principle enables high energy
efficiency with minimal electrical consumption, as the power of the
electromagnets does not directly influence the system’s output. Instead, the
electromagnets serve only to control the direction of the permanent magnet’s
movement.
NIMEC linear modules operate fully within the bounds of physical law, offering
consistent performance, long service life, and exceptional controllability.
The modules can be built to be extremely compact and virtually silent, making
them an ideal solution for precision positioning systems, robotics, automated
transport applications, and next-generation energy systems.
The NIMEC linear drive system is designed as a modular architecture based on
compact energy cells, within which controlled magnetic interaction is
implemented. Each cell includes two electromagnets with 100% copper windings
and cores made from high-performance Permendur alloy, known for its exceptional
magnetic permeability. Positioned between the electromagnets is a cylindrical
permanent magnet made of NdFeB, class N52M — one of the most powerful
commercially available magnetic materials today.
Standard industrial energy cells are produced in both cylindrical (600 mm
height, 300 mm diameter) and rectangular (300 mm height, 300 mm width, 600 mm
length) formats. These dimensions are optimised for efficient energy output and
seamless integration into existing industrial systems. For use in drones,
robotics, and mobile platforms, cells are custom-designed to meet strict
spatial and weight constraints.
Each cell functions as a self-contained module with an integrated control unit
and ultracapacitors, delivering precise impulses to the electromagnets. In
multi-cell configurations, control electronics and power modules can be grouped
externally to maximise compactness and streamline system architecture.
Every cell is securely housed in a casing made from non-magnetic,
impact-resistant composite material, providing robust protection against
external influences and vibration. The structure also incorporates a passive
noise suppression system, enabling near-silent operation even during
high-frequency cycling. This feature is especially valuable in applications
requiring a low acoustic signature — from laboratory settings to sound-sensitive
industrial environments.
Modern materials make it possible to create flexible cylinders capable of
deforming in response to external forces. When the pistons of such cylinders
are fitted with powerful permanent magnets, the NIMEC linear module can be
adapted to control their movement. This solution is suitable for fluid
circulation systems — including biomedical applications — as well as for
simulating muscle contractions in robotic and exoskeletal systems, where
smooth, natural motion is essential.
In aquatic environments, NIMEC linear impulse modules can be applied in
next-generation jet propulsion systems — without blades or rotating components.
This approach enables the creation of directed flows with high speed and
precision, significantly enhancing the performance of both underwater and
surface vehicles. The technology holds particular promise for high-speed
platforms such as marine scooters.
For aerial systems, NIMEC’s linear solutions signal the beginning of a new era.
With ultra-low energy consumption, high reliability, and no moving mechanical
parts subject to wear, these modules enable drones and autonomous flying
platforms to achieve extended flight times, reduced weight, and stable
operation even under demanding conditions.
