48V 200W Permanent Magnet Generator Three Phase Wind Turbine Efficiency Direct Drive

48 V, 200 W three phase permanent magnet generator designed for reliable low speed direct drive use Key benefits Stable and efficient power: NdFeB rare earth magnets and pure copper windings deliver consistent output with a conversion efficiency of at least 85 percent. Durable construction: Aluminum alloy casing with anti corrosive treatment resists alkali and salt exposure for longer service life. Good thermal control: Specially designed rotor provides low starting torsion and effective cooling to limit temperature rise during operation. Gearless direct drive: Low speed, gearless design reduces mechanical losses and simplifies installation and maintenance. Easy to maintain: Grease lubrication access and robust carbon steel main shaft keep routine service simple. Performance and features Nominal voltage: 48 V Rated power: 200 W Generator type: Three phase rare earth permanent magnet generator Rated speed: 750 rpm Number of magnetic poles: 12 Conversion efficiency: at least 85 percent Working temperature rise: not exceeding 70 C Housing material: aluminum alloy with anti corrosive treatment Magnetic material: NdFeB rare earth magnets Windings: pure copper Main shaft: carbon steel Lubrication mode: add grease Insulation class: H class Gross weight: 3950 g Product size: approximately 15 x 13.5 x 16.5 cm Practical applications and scenarios Small wind turbines: Direct connection to low speed blades in locations with sufficient wind resources. Suitable where average wind speeds are above 3 m per second, effective wind speeds of 3 to 20 m per second occur for roughly 3000 hours per year, and average wind energy density in that range is around 100 W per square meter. Off grid power systems: Use as a compact AC generation source for remote cabins, boats, or small renewable installations that require a 48 V input. Experimental and demonstration setups: Ideal for educational projects, prototype wind or micro hydro rigs that need a reliable three phase permanent magnet generator at low rpm.
