3kW Low RPM Axial flux coreless permanent magnet generator for vertical wind turbine

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.
Magnetic Generator Product DescriptionMagnetic Generator Overview
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 turbinesHigh efficiency and Low mechanical resistance energy loss.Excellent heat dissipation due to the Aluminum alloy outer frame and special internal structure.

FAQ
1. Q: Does installation Easy ?
A: Very easy, every customer can doing by themselves, we will supply all the components for installation and very detailed installation manual.
2. Q: Does our wnd is enough for a wind generator ?
A: As our wind generator can start running at low wind speed 3m/s. so your average annual wind speed is more than 5m/s then you can use it .
3. Q: Which model wind generator is suitable for me?
A: Plese contact our sales with following points :
1. What appliance do you want to running by the system? How many watts are they and their working time .
2. Your annual wind speed .
3. What kinds of system do you want ? On-grid or off-grid
4. Q:Can I only buy parts not whole system?
A: Yes,for example you can manufacture tower in local , we can suplly you tower drawing .
Any other questions ,please feel free to contact us .
