Synchronous PM Alternators (permanent magnetism)

A “conventional wisdom” teaches us that a generator when driving non-linear loads should be provided with a geometric overdimension factor of 2 to 8 x the nominal capacity!
Knowing that this “wisdom” is not based on a fixed guideline and is rather a technical consensus, these recommendations often lead to expensive oversizing of the generator in question.
Even if the oversizing is only limited to a factor of 2 for non-linear loads, this leads to unnecessary installation, operational and periodic maintenance costs, not least because the generator runs underload for a long time!
Non-linear and other electronic loads often require a higher degree of stability in voltage and frequency than, for example, linear loads.
Sometimes it is forgotten that a generator is not an equivalent of a mains power source.
With heavy peak loads and dead moments, it is not uncommon for voltage drops of 5% and more to occur for short periods with frequency fluctuations of around 10 to 15 Hz!
Most users no longer question this!
In practice, this phenomenon of overdimensioning continues to be accompanied by far too high operating costs!
Anyone who invests in our PM technology will get rid of these classic problems!
PM technology offers the best solution for your non-linear loads without compromise & limitations!
From now on, you get rid of the old problems, and the electrical performance is greatly increased.
The voltage and frequency are thus stable, accompanied by a perfect active and reactive output power!
As a result, capacitive and inductive loads are no problem at all for these alternators.
Moreover, compared to the classical electromagnetic alternators, the PM alternators have a noticeably higher dynamics.
This makes the PM alternator a “High-tech” super-efficient and energy-saving alternative that guarantees extremely high and unprecedented performance.
With energy savings of up to +50% (similar applications can now also be seen in PM screw compressors, with the same high energy savings).
The PM alternator is constructed around a stator and field winding in the same way as the conventional alternator.
The armature is made of an ALU alloy, equipped with encapsulated high-quality NdFeB magnets, which creates its permanent magnetic field, in contrast to the classic generators where the magnetic field has to be activated.
The housing is compact and uses the same SAE sizes.
A patented motor/alternator connection provides the IP 55, insulation class, which neutralizes the impact of dust and moisture.
Finally, it is important that we are the only ones who have succeeded in applying PM technology to generators without using an inverter, which significantly reduces the price, but also that these alternators are extremely reliable.
Years of intensive research have preceded this technology, resulting in a complete line of PM alternators in 3000 rpm for powers up to 9 KW and 1500 rpm for powers from 13 to 60 KW.
However, the pricing for PM technology is more expensive than conventional alternators, but taking into account the efficiency of the generator increases by a factor of 50%, resulting in savings on fuel, logistics, and maintenance.
Then this additional cost is negligible, certainly where the problem arises as described above with regard to the non-linear load.
