Product Specification
| High Light | coreless permanent magnet generator for wind power ，rare earth permanent magnet generator ，low start torque wind generator | ||
The GREEF NEW ENERGY GDG series disc-type permanent magnet generator features a unique spindle and rotor arrangement in a disc shape configuration. The stator is fixed at the center while rotors rotate on both sides, with the spindle containing only windings and no iron core.
Both stator and rotor are constructed in flat disc form utilizing axial air gap magnetic flux, alternately positioned along the axial direction. This compact design combines short axial dimensions with large diameter, easily accommodating multi-pole structures.
Key advantages include high power-to-mass ratio, low speed rating, low wind speed starting capability, small size, low energy consumption, lightweight construction, compact structure, and high efficiency. Ideal for direct-drive vertical axis wind turbines where low rotor wind resistance is essential.
Available in two variants: outer rotor (stationary shaft, non-rotating casing, center cable exit) and inner rotor (rotating shaft, stationary casing, external cable routing).
Greef offers customized Coreless Permanent Magnet Generators model GDG, manufactured in Qingdao. Our inner-rotor generator design ensures high power density and efficiency for various applications.
