Advantageous Features
High efficiency at low speed

No mechanical drive losses, no rotor copper losses due to the permanent magnet excitation and no stator eddy current losses in the ironless (coreless) stator

The efficiency of AFPMG, depending on the model, is up to 90%.

Small dimension and weight

AFPMG is uniquely lightweight and compact and construction is simple. The generators use much less metal in their construction.

The generator's small weight and dimension make it possible to reduce the size and price of the whole wind turbines.

Very Small Maintenance Costs
The highest energy efficiency at low speeds in the industry means that the generators can support any type of wind turbines with the widest range of wind speed.

The use of air-cooling reduces maintenance costs and also significantly strengthens the autonomy of power units

Very Low Starting Torque
AFPMG has no cogging torque and torque ripple, so the starting torque is very low. For direct-drive small wind turbine (SWT), the starting wind speed is less 1m/s.

Superior Reliability
Very low noise, less vibration, no mechanical belt, gear or lubrication unit, long life

Environmentally Friendly
The 100% environmentally clean technologies and materials are used in production during the long service life and the future recycling is absolutely harmless for the environment.

Main Applications
1. Small wind generators (SWT)

2. Small electrical generators driven by gasoline or diesel engines

3. Electric vehicle drive machines, as motor and generator.

4. Hydro Power
