Frequently Asked Questions

What customization options do you offer for your permanent magnet generators?

We can customize key technical specifications based on your specific requirements, including rated voltage (from 48V to 1140Vac), rated speed (20 to 3000 rpm), rated power (0.5KW to 5500KW), frequency (50Hz/60Hz), and mechanical installation configurations.

Why are direct-drive permanent magnet generators better for wind power?

Direct-drive permanent magnet generators eliminate the need for a gearbox. This allows them to run reliably at low rotor speeds and high torque, reducing mechanical wear, increasing total system efficiency, and lowering long-term maintenance costs.

What kind of materials are used in your generators?

We construct our generators using high-grade materials, including rare earth NdFeB (Neodymium Iron Boron) permanent magnets, 100% pure copper windings, a strong cast iron shell, a high-quality steel shaft, and cold-rolled silicon steel sheets for the iron core. Premium SKF bearings are also used to ensure long life.

Are these generators maintenance-free?

Yes, our permanent magnet generators are designed to be maintenance-free. With their simplified structure, high-grade components, and absence of gearboxes or brushes, they are capable of running continuously (24/7) in harsh and remote environments without regular maintenance.

What is the expected lifetime and efficiency of your generators?

Our permanent magnet generators boast a design lifetime of more than 20 years. They offer outstanding energy conversion performance, achieving working efficiencies exceeding 95% with a power factor close to 1.
