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. This means lower operating costs, faster return on investment, and a sustainable advantage that conventional motor designs simply cannot match.

The operating principle of NIMEC’s rotary motor is rooted in the very nature of magnetic interaction. Magnets exhibit two fundamental forces — attraction and repulsion. The strength of attraction depends on the distance between poles and the intensity of their fields, and practice consistently shows that attraction significantly outweighs repulsion. To fully harness this potential, we employ an axial configuration: magnets are arranged on an aluminium disk with alternating poles. This prevents the field from short-circuiting into the magnetic material and weakening it, while ensuring that the electromagnetic field closes only through the iron cores, delivering a concentrated and controllable effect.

By applying high-permeability materials such as Permidur for the cores, we capture the maximum efficiency of both permanent and electromagnetic attraction. Positioning the magnets at a calculated distance from the edge of the disk further amplifies torque through the leverage effect transferred to the shaft. When the polarity of the electromagnet is switched, repulsion occurs. Yet, neighbouring magnets simultaneously seek attraction to the core, which could otherwise hinder rotation. To neutralise this effect, one side of the core is shielded, allowing the system to reach a state of dynamic equilibrium where continuous motion is sustained by the combined fields of the next permanent magnet and the electromagnet.

What drives the process is not mysticism or speculation, but pure physics: precise calculation, rational geometry, and the right choice of materials. In this way, NIMEC transforms natural laws into mechanical power.

At NIMEC, every motor is custom-built — we do not produce standard, off-the-shelf solutions, but design and manufacture units tailored precisely to the specific requirements and tasks of each client. This approach allows the system to be adapted to the characteristics of the mechanism, operational conditions, and desired power output, creating unique solutions unavailable from mass-market manufacturers. Our motors can drive shafts of various industrial mechanisms, hydraulic pumps, and fluid systems of any type — from water to specialised technical fluids — providing stable rotation and maximum efficiency.

The cost of each unit is determined by a variety of factors: power, geometry, materials, durability requirements, and specific operational conditions. Pricing is calculated individually to ensure an optimal balance between efficiency, reliability, and economic feasibility. This approach allows our clients to accurately plan their investments, achieve high returns from technology implementation, and have confidence that the motor perfectly meets their production and technical needs.

Every NIMEC solution is not merely a motor, but a tool for enhancing productivity and economic performance, where engineering precision and innovative magnetic technologies combine to transform the potential of magnetic fields into tangible advantages for your business.
