Low RPM NdFeB Rare Earth Permanent Magnet Generator for DIY Projects Models M2500, M2600, M2800, M21000 Overview This permanent magnet generator is designed for low RPM wind and small renewable energy applications. It uses rare earth NdFeB magnets and a specially shaped stator to reduce resistive torque, allowing reliable operation at low start speeds. The unit is gearless, compact, and intended for easy installation and maintenance. Key benefits Low startup torque and low RPM operation: designed to produce power at lower rotor speeds, making it suitable for small wind turbines and lowwind conditions. magnetic flux and efficiency: NdFeB rare earth magnets and an optimized stator reduce resistance torque and improve conversion efficiency. Simple installation and maintenance: humancentered mechanical design and included installation hardware reduce assembly time and simplify repairs. Robust construction for outdoor use: aluminium alloy shell and IP55 protection grade provide basic protection against dust and water spray. Flexible voltage and power options: available in multiple wattages and voltage outputs to match different battery systems and small offgrid setups. Technical highlights Models: M2500, M2600, M2800, M21000 Wattage options: 500W, 600W, 800W, 1000W Voltage options: 12V, 24V, 48V Rated speed: 500 rpm Permanent magnet material: Rare Earth NdFeB Generator shell material: Aluminium alloy Shaft material: iron or stainless steel depending on model Protection grade: IP55 Type: gearless permanent magnet wind generator Color: white, without base What is included 1 PC generator 1 set installation screws Performance and design details Gearless design eliminates gearbox maintenance and reduces mechanical losses. Ringstyle power output device minimizes issues related to traditional cable winding. The rotor uses alternatorstyle construction paired with a special stator to lower generation resistance torque and improve matching between turbine and generator. Intended to run reliably in smallscale systems and to improve overall conversion rates compared to basic generators. Suitable applications Small wind turbine builds for offgrid battery charging at 12V, 24V, or 48V systems. Hybrid micro generation systems combined with solar panels for cabins, workshops, or remote lighting. DIY and educational projects where low RPM performance, clear installation, and straightforward maintenance are needed. Compatibility and installation notes Choose model and voltage to match your battery bank and charge controller requirements. The product is supplied without a mounting base; a compatible base or hub must be arranged separately. Installation hardware is included for initial assembly; follow safe mechanical and electrical practices when connecting to battery systems or controllers. This generator is intended for DIY and small renewable installations requiring a gearless, low RPM permanent magnet machine with NdFeB magnets, multiple power and voltage options, and straightforward maintenance.
