Permanent Magnet Generator: An Overview of Its Functionality and Applications
Permanent Magnet Generator: How It Works and Where It's Used
This article will show you how these generators work and where we use them. As a leading NdFeB Magnets Factory, we can tell you that making magnets for generators is one of our specialties.

What is a Permanent Magnet Generator?
A permanent magnet generator is like a motor that makes power. It uses magnets and wires to do this. The magnets are permanent, which means they always have power.
How it Works:
- A part called the rotor spins around. It has magnets on it.
- Another part called the stator has wires. It does not move.
- When the rotor spins, the magnets make power in the wires. This is called electromagnetic induction.
Two main kids
- Axial flux generator: The magnetic part goes side-to-side.
- Radial flux design: The magnetic part goes out from the middle.
Why are our magnets so good? Because we are an NdFeB Magnets Factory we have NdFeB magnets. These magnets are very strong. They make lots of magnetic flux density. [^1] This makes the generator work better.
Good Things About PMGs
- Efficiency: They do not lose much power. Eddy current losses are low.
- Durablity: They do not have brushes. So, they do not need much care.
- Small: We put our strong, Customized Neodymium Magnets in high power PMG‘s!
We are a NdFeB magnet manufacturer. We make magnets in all shapes. Do you need special magnets for your very own tiny PMG? Check out our catalog!
Where Do We Use PMGs?
- Wind Turbines: We use them with no gearbox. This is good for wind power.
- Electric Vehicles: They help get power back when you slow down.
- Boats and Planes: They do not weigh much.
Backup power: they even help to keep the power on when the main power has a fault.
Big wind power companies trust our magnets. We are a NdFeB magnet manufacturer. Our magnets work in wind turbines and electric cars.
How NdFeB Magnets Make PMGs Better
The main magnet
- Strong: They make lots of power (Up to N52 and higher!).
- Stay strong in heat: They work up to 200°C.
- Any shape: We make them in any shape you need.
True Story: One company used our magnets. They made their PMG 25% lighter!

Things to Think About When Making PMGs
- Rotor and Stator:
- Make the magnetic part good.
- Keep a good space between the rotor and stator, in an area called the Air gap.
Thermal Mangament:
- Heat: Stop the magnets from losing power with things like a good Cooling.
- Save Money: Using our very best Magnet Grade will pay for itself in the long run.
We help people make PMGs. We pick the best, cheap magnets.
Picking the Right NdFeB Magnets
Important Things:
- Grade: N35 to N52.
- Coating: Use nickel, epoxy , or PPS in tough places. Looking for a special Magnet Coating? Request information now!
