72V 2000W Brushless Permanent Magnet DC Generator Key Specifications Power: 2000W Output voltage options: 36V, 48V, 60V, 72V DC (this listing is for the 72V model) Type: Brushless permanent magnet DC generator Operating speed: up to 4000 rpm; requires more than 1200 rpm to charge Weight: approximately 3 kg / 6.61 lbs Construction: pure copper coil, aluminum shell, cast iron flywheel Package: 1 generator Why this generator Reliable power for engines and equipment: 2000W continuous output supports speed motor operation and stable electrical supply for charging and lighting. Efficient copper windings: pure copper coil lowers resistance and heat, improving conductivity and reducing energy loss for longer motor life. Quiet, lowmaintenance operation: brushless design reduces electrical interference, noise, and wear compared to brushed generators. Durable build: aluminum casing resists corrosion and wear, while a cast iron flywheel provides strength and easy, lowcost repairs if worn. Performance and compatibility Works with single cylinder diesel engines and agricultural tractors; the generator can charge a battery while the diesel engine is idling, provided engine RPM exceeds 1200. Wiring method: connect the battery positive to the generator positive terminal through the live wire controlled by the ignition key; the battery negative can be grounded for charging and lighting. Voltage regulator note: 12V and 24V versions include a builtin voltage regulator. Models at 36V, 48V, 60V, and 72V require a voltage stabilizing charging module for stable charging; a voltage stabilizer is provided for these highervoltage models. Materials and construction details Pure copper coil: lower resistance and heat generation for smoother current, higher efficiency, and extended generator life. Brushless motor design: fewer moving electrical contacts means lower interference and longer service life. Aluminum shell: lightweight and resistant to corrosion and wear for extended field use. Cast iron flywheel: hard, pressure resistant, and simple to if worn. Practical benefits Fast power generation: speed enables quick and stable electricity output, saving time during operation. Portability: compact size and light weight make it easy to carry and install on small equipment. Energy saving: allcopper windings improve conversion efficiency and reduce heat loss. Typical use scenarios 1. Agricultural tractor charging: install on a tractor to charge the battery and power lighting while the engine runs at idle or above 1200 rpm. 2. Single cylinder diesel engine application: pair with small diesel engines for reliable onboard power and lighting in remote or offgrid situations. 3. Workshop or farm equipment: supply stable DC power to speed motors or lighting systems where a robust, lownoise generator is needed. What is included and important notes Included: 1 generator Note on voltage regulation: 12V and 24V units include an internal regulator. 36V, 48V, 60V, and 72V units need a voltage stabilizing charging module for stable charging; a voltage stabilizer is supplied with these models. Operating requirement: generator needs more than 1200 rpm to charge effectively; it can charge while the diesel engine is idling if this rpm threshold is met. This generator is designed for users who need a compact, efficient, and durable DC power source for small diesel engines, tractors, and similar equipment.
