Frequently Asked Questions (FAQ)

Q1: What are the primary application fields of your Permanent Magnet Generators?

A1: Our generators are highly versatile and widely used in wind power systems, micro-hydropower generation, ocean tidal energy, marine vessels, aviation systems, diesel generator sets, and hand-crank backup systems.

Q2: Can we customize the specifications of the permanent magnet generator?

A2: Yes. Since we operate our own manufacturing facility, we offer full customization options matching your specific requirements for output voltage, rated speed, rated power, and frequency.

Q3: What are the advantages of a direct-drive generator design?

A3: The direct-drive configuration eliminates the need for a gearbox. This enables high-torque output at lower rotor speeds, reduces mechanical failure rates, eliminates gearbox maintenance costs, and maximizes overall energy conversion efficiency.

Q4: What material is used for the magnets and windings?

A4: We use premium NdFeB (Neodymium Iron Boron) rare earth permanent magnets which can withstand temperatures up to 120℃, paired with 100% pure copper windings (class H insulation, max 180℃) for optimal electrical conductivity and lifespan.

Q5: What is the typical life expectancy and maintenance cycle of these generators?

A5: Thanks to features like SKF bearings, a robust cast iron outer shell, and direct-drive transmission, our generators are completely maintenance-free and designed for continuous 24/7 high-speed operation with a lifespan exceeding 20 years.

Q6: What is the protection rating and efficiency level of your generators?

A6: Our permanent magnet generators reach an operational efficiency of over 95%. They feature an IP54 rating, providing outstanding protection against dust entry and water splashes in harsh outdoor environments.
