50kW Direct Drive Permanent Magnet Generator NdFeB 20 Year Lifespan 380V
50kW Direct Drive Permanent Magnet Generator NdFeB 20 Year Lifespan 380V
This 50kW direct drive permanent magnet generator is built around NdFeB neodymium magnets and a 20-year design lifespan. With no gearbox and no excitation system, this permanent magnetic generator removes the two most failure-prone parts of a renewable drivetrain, delivering 380V at a quiet 250rpm for decades of service.
Key Features
- Direct drive gearless design eliminates gearbox loss, noise and maintenance
- NdFeB neodymium magnets rated for 20-year demagnetization resistance
- 380V three phase output for standard industrial and inverter loads
- 250rpm low speed matches hydro runners and wind rotors directly
- 96% efficiency with natural cooling for silent continuous operation
