Our Advantage
An axial flux generator is a type of electric generator that uses a geometry where the magnetic flux between the rotor and stator is aligned parallel to the axis of rotation, rather than radially as in conventional generators.
Some of the advantages of axial flux generators are:
• They have a compact structure, especially short axial sizes, which can reduce the weight and size of the generator.
• They have a high torque density and high power density, which means they can produce more torque and power per unit volume than conventional generators.
• They have a small end-winding, which reduces the copper losses and improves the efficiency of the generator.
• They have an excellent cooling performance, because the air gap between the rotor and stator is large and allows for better heat dissipation.
• They can be easily integrated with other components, such as printed circuit boards, and use rectangular copper strips for the windings, which simplifies the manufacturing process.
• They can operate at low speeds and generate useful voltages, which makes them suitable for applications such as wind turbines and tidal current power generation.
