GreeF company supply modified kinds of Coreless Disk Permanent Magnet Generator. The main models are as follow:
Outer Rotor Model:
The shell will rotate to produce electricity, the shaft is fixed.
Inner Rotor Model:
The shaft(axis) will rotate to produce electricity, the shell is fixed.
The magnetic generators are always being used in vertical axis wind turbine generator, hydroelectric generator(water-power generator) and other generator system which requests very low start torque and low RPM.
The coreless disk permanent magenetic generator is made of high-stability Nd-Fe-B materials.
The specific outer rotor magnetic circuit is designed in a special way. The magnetic generator
has following features:
Low starting torque, Low start wind speed, Low weight,small size ,High generating efficiency
Torque Patent Technology: use newest “Precise Coil” technology. No hysteresis and gear notches effect make the start torque very low <1N.M
