The axial flux ironless core generator is a type of generator that utilizes an axial flux design and an ironless core structure. It differs from conventional generators in that it avoids iron core losses and hysteresis losses. Instead, it generates electricity by utilizing axial magnetic flux.
The structure of an axial flux ironless core generator typically consists of permanent magnets, coils, and casing. The permanent magnets generate the magnetic field, while the coils capture the energy in the magnetic field and convert it into electrical energy. The casing is used to protect the internal structure of the generator and provide it with sturdy support.
The principle of operation for an axial flux coreless generator is based on the principle of electromagnetic induction. When the magnetic field generated by a permanent magnet moves relative to a conductor in a coil, an induced electromotive force is generated in the conductor. This electromotive force can then be converted into electrical energy, providing power to external devices.
Wind power generation has great potential with the use of axial flux coreless generators. These generators are particularly effective in megawatt-class wind turbines, as they can significantly increase output density and enhance the efficiency of wind power generation. Due to the absence of an iron core, these generators demonstrate reduced iron losses and hysteresis losses, ultimately making them more efficient.
Axial flux coreless generators have a wide range of applications in renewable energy, including solar and wind power generation systems. These generators are highly efficient in energy conversion and reliable in operation, making them ideal for renewable energy generation systems.
The axial flux coreless generator is also suitable for use in other industrial applications that require an efficient, lightweight and reliable power supply. As an example, it can be employed as a backup or auxiliary power source to offer stable power support for industrial equipment.
The flexibility of the axial flux ironless core generator means that it can be customized based on customers’ specific needs. It allows for the adjustment of various parameters, such as generator power, speed, and output voltage to meet the requirements of various application scenarios.
The GDG Coreless Permanent Magnet Generator comes with multi-poles ranging from 16-20 and voltage range of 12-450V. The protection grade is IP 54 and it has a speed range of 100-500RPM. You can choose between an outer-rotor or inner-rotor structure to suit your requirements.
