Product Description
Frequency 50/60Hz Coreless Wire Coil Equipment
Providing Higher Reliability and Enhanced Durability in Harsh Environments
Product Overview
The GDG series disc type permanent magnet generator by GREEF New Energy features an innovative coreless design where the spindle and rotor are arranged in a disc shape. The stator is fixed centrally while the rotor rotates on both sides, utilizing axial air gap magnetic flux technology.
This unique design results in a high power-to-mass ratio, low rated speed, and efficient startup at low wind speeds. The compact size, light weight, and reduced energy consumption contribute to its overall high efficiency, making it ideal for direct-drive vertical axis wind turbines.
Key Features
-
Low Start Torque TechnologyEliminates hysteresis and gear notch effects with starting torque less than 0.1 N*m for smoother startup performance.
