Product Description:
Axial flux ironless core generators are a type of generator that
utilizes an axial flux design and an ironless core structure to
produce electrical power. These generators rely on axial magnetic
flux to generate energy while avoiding the common losses associated
with conventional generators, such as iron core losses and
hysteresis losses.
The structure of these generators typically consists of permanent
magnets, coils, and casing. The permanent magnets generate the
magnetic field, while the coils capture the energy from the
magnetic field and convert it into electrical energy. The casing of
the generator is used to protect the internal structure and provide
support.
The principle of operation for these generators is based on
electromagnetic induction. As the permanent magnet's magnetic field
moves relative to the conductor in a coil, it generates an induced
electromotive force in the conductor. This force can then be
converted into electrical energy to power external devices.

Applications:
Wind power generation:
Axial flux coreless generators have demonstrated significant
potential in wind power generation, particularly in megawatt-class
wind turbines. These generators can increase the output density and
efficiency of wind power generation.
The absence of an iron core greatly reduces iron and hysteresis
losses, which contributes to making the generator more efficient.
Renewable Energy:
Axial flux coreless generators can be used in a wide range of
renewable energy applications, including solar and wind power
generation systems. These generators are highly efficient in energy
conversion and can operate reliably, making these systems ideal for
renewable energy sources.
Other industrial applications:
Axial flux coreless generators are not limited to renewable energy
applications, but can also be used in other industrial settings
where reliable and efficient power supplies are needed. For
instance, they can be used as a backup or auxiliary power source to
provide stable power support to industrial equipment.
Customized applications:
The axial flux coreless generator has a flexible structure, which
makes it possible to customize it based on individual customer
requirements. For example, parameters such as the generator's
power, speed, and output voltage can be adjusted to accommodate
different application scenarios.
