20KW 60RPM 400v DC three Phase PMG permanent magnet alternator coreless maglev Low RPM Low Torque generator motor
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 Maglev generator, depending on the model, is up to 98%.
Small dimension and weight
The Maglev generator is uniquely light weight and compact, construction is simple. The generators use much less metal in their construction, while also being highly durable and having a long life.
The generator's small weight and dimensions make it possible to reduce the size and price of the whole wind turbines.
The high specific capacity (output capacity per unit weight) significantly outperforms those from competing producers. This means that with similar dimensions and weight
Small maintenance costs
Direct drive, no gearbox, oil-free system, low temperature rise
The highest energy efficiency at low speeds in the industry means that the generators can support any type of wind turbine with the widest range of wind speed.
The use of air-cooling reduces maintenance costs and also significantly strengthens the autonomy of power units
Low starting torque
Maglev generators have no cogging torque and torque ripple, so the starting torque is very low, for small wind turbine , the starting wind speed is less 1m/s.
Superior reliability
low noise, less vibration, no mechanical belt, gear or lubrication unit, long life
Environmentally friendly
The 100% environmentally clean technology and materials used in production during its long service life and the future recycling are absolutely harmless for the environment.
Applications
- Vertical axis wind generators
- Small electrical generators driven by gasoline or diesel engines
- Electric vehicle drive machines, as motor and generator.
- Hydro Power
