Frequently Asked Questions (FAQ)

Can these permanent magnet generators be customized?
Yes. We offer fully customized solutions matching specific requirement metrics. You can request customizations for Rated Voltage, Rotate Speed, Rated Power, Frequency, mounting options, and shaft dimensions.
What makes them highly suited for wind turbines?
They are direct-drive generators, which means they do not require an integrated gearbox. This system allows for higher efficiency, reliable low rotor speed outputs, and excellent torque handling capacity suitable for off-grid, medium, and offshore wind power setups.
What kind of magnet material is used?
We use high-grade NdFeB (Neodymium Iron Boron) rare earth permanent magnets, which enable high efficiency, stable voltage, and a lifespan exceeding 20 years under heavy operation.
Do these generators require high maintenance?
No, they are practically maintenance-free. Because there are no mechanical gears or excitation windings, common wear-and-tear points are eliminated. The IP54 rating makes them highly resistant to environmental contaminants.
What is the typical operating temperature limits?
Our permanent magnets are rated to withstand temperatures up to a maximum of 120℃, while the high-quality copper windings are rated up to a maximum temperature level of 180℃.
