Low RPM Axial flux coreless permanent magnet generator
50W-20kW
They have two types: Outer Rotor and Inner rotor
Outer rotor: The shell will rotate to produce electricity, the shaft is fixed.
Inner rotor: The shaft 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. Magnetic Generator Overview
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
- Original Structure: use disc coreless motor to take place traditional motor makes it less volume and weight.
- Higher Utilization: use special coreless motor technology to eliminate the use bottlenecks of lower speed wind energy.
- Higher Reliability: special structure make it bigger ratio of power to volume, power to weight and have long life of 8 times longer than traditional motor.
- Gearless, direct drive, low RPM generator.
- High standard, quality components for use in harsh and extreme environments for wind turbines
- High efficiency and Low mechanical resistance energy loss.
- Excellent heat dissipation due to the Aluminum alloy outer frame and special internal structure.
