What Is A Permanent Magnet Generator?

As the old saying goes, “A picture is worth a thousand words.” When it comes to permanent magnet generators (PMGs), this couldn’t be more true. PMGs are highly efficient and powerful machines that generate electricity from magnets alone – no fossil fuels required! These innovative machines have become increasingly popular among both homeowners and businesses looking for sustainable energy sources.

So just how do these amazing devices work? Well, at their most basic level, PMGs rely on electromagnetism to create current flow. This is done by using magnets with opposite poles facing each other within the generator’s coils. As they spin in relation to one another, an electrical charge is created which then passes through the coils producing the desired output of electricity. It really is remarkable technology!

With so many advantages over traditional forms of power generation, such as reduced emissions and cost savings, it’s easy to see why PMGs have grown in popularity worldwide. Now let’s take a closer look at some of the different types available…

Types Of Permanent Magnet Generator

Let’s talk about PMGs! There are two main types of PMGs, Axial flux and Radial flux. Axial flux PMGs use magnets that are placed in a line between the rotor and stator, while Radial flux PMGs have magnets placed around the circumference of the rotor. I’m an expert on PMGs and I’m available to answer any questions you have about the differences between these two types.
