Frequently Asked Questions (FAQ)

What are the main application areas for your permanent magnet generators?
Our permanent magnet generators are widely used in wind power generation, hydropower, ocean energy systems, marine vessels/ships, diesel generators, aviation and military setups, as well as portable hand-crank generators.
Why are permanent magnet generators ideal for wind turbines?
They are exceptionally suited for direct-drive turbines since they eliminate the need for a complex gearbox. They can work reliably at low rotor speeds while maintaining high torque efficiency, which is perfect for small, medium-sized, offshore, and off-grid wind power systems.
What customization options do you provide?
We custom-engineer generators from our own factory. We can tailor the specifications to meet your exact needs for parameters such as Rated Power (ranging from 0.5KW to 5500KW), Rated Speed, Voltage (from 48Vac up to 1140Vac), and Frequency.
What is the lifespan and maintenance requirement of these generators?
Our generators use rare earth Nd-Fe-B (Neodymium Iron Boron) permanent magnets and high-grade SKF bearings, giving them a long service life of over 20 years. They are completely maintenance-free and designed to run continuously (24/7) at high speeds in all environments.
What are the thermal limits and insulation class specifications?
The permanent magnet temperature level is rated up to a maximum of 120℃, while the winding temperature level is designed to handle up to 180℃. The system features Class H insulation to guarantee safety and stability during long-term operations.
What are the construction materials and protection ratings?
The generator shell is constructed from durable Cast Iron with a steel shaft, a cold-rolled silicon steel sheet iron core, and 100% copper windings. It carries an IP54 protection rating and achieves an efficiency rating greater than 95%.
