Frequently Asked Questions

What are the primary applications of these permanent magnet generators?

They are highly versatile and widely used in wind power systems, small to medium-sized hydropower stations, ocean energy harvesting, marine ship power, diesel generator backups, hand-crank emergency units, and aviation/military systems.

Why are direct-drive generators beneficial for wind power generation?

By using a direct-drive setup, these generators eliminate the need for a mechanical gearbox. This allows them to operate reliably at low rotor speeds with high torque output, greatly reducing power loss, noise, and ongoing maintenance.

What specifications and parameters can be customized?

We support tailored designs matching your specific application. Customizations include voltage outputs (from 48V to 1140Vac), rotation speeds (20 to 3000 rpm), power capacities (0.5 to 5500KW), frequency options (50Hz or 60Hz), and installation dimensions.

What materials are used to ensure the generator's long service life?

Our generators feature rare earth NdFeB permanent magnets rated up to 120°C, 100% pure copper windings with high-grade H insulation (rated up to 180°C), premium SKF bearings, a high-durability steel shaft, and a robust cast iron shell.

What protection level and efficiency can be expected?

The generators have an IP54 protection level, making them suitable for use in varied outdoor and marine environments. Under standard operating conditions, they maintain a highly efficient output exceeding 95% with a power factor close to 1.
