JAVAC Nanomag alternator – powerful and efficient PM technology

The Nanomag alternator from JAVAC is a synchronous PM alternator (Permanent Magnet) that represents a revolution in energy efficiency and reliability.
Where conventional alternators often need to be heavily oversized for non-linear loads, the Nanomag alternator offers a much more compact, more stable and more energy-efficient solution.

Efficiency without oversizing

Traditionally, it is assumed that generators for non-linear loads need to be oversized by as much as 2 to 8 times.
This “rule of thumb” often leads to unnecessarily high installation, maintenance and fuel costs.
The Nanomag alternator breaks with this outdated practice: thanks to PM technology, it delivers perfectly stable voltage and frequency, even under heavy or sudden loads.

Voltage drops and frequency fluctuations—often up to 15 Hz with conventional generators—are now a thing of the past.
The Nanomag alternator guarantees stable voltage, active and reactive power and eliminates the need for costly overcapacity.

High-tech performance with permanent magnetism

The PM technology in the Nanomag alternator delivers energy savings of up to 50%.
Voltage and frequency remain constant, even with capacitive or inductive loads.
The alternator is built from an aluminum alloy with high-quality NdFeB magnets, which create a permanent magnetic field.
As a result, no excitation is required as with conventional electromagnetic alternators.

This innovative design results in a compact housing, featuring IP55 protection and insulation class H, so dust and moisture have no impact on operation.

Reliable without an inverter

What makes the Nanomag alternator unique is that JAVAC is the only manufacturer to have applied PM technology without using an inverter.
This not only reduces the cost price, but also significantly increases reliability.
After years of research, this has resulted in a complete range of PM alternators:

3000 rpm models with power outputs up to 9 kW
1500 rpm models with power outputs between 13 and 60 kW

Although the purchase price is slightly higher than that of conventional alternators, the 50% higher efficiency delivers substantial savings on fuel, maintenance and operating costs.

A sustainable investment

The Nanomag alternator is the ideal choice for those looking for an energy-efficient, highly reliable and low-maintenance alternative to conventional generators.
With low energy consumption, high stability and a long service life, this is the future of reliable power generation—both in industrial and mobile applications.
