Silent Electricity – Low‑RPM Permanent‑Magnet Dynamo Generator 20 kW + 500w DC motor

Abundant autonomy step one; Capture the hum of hidden power with this Low‑Noise, Low‑RPM Permanent‑Magnet Generator, available in 20 kW. Designed for mobility & efficiency at a volume far quieter than conventional generators, it is ideal for off‑grid lighting, electrification, water pumping, or general discreet backup power—anywhere you need dependable current without the roar of engines.

This machine stands on the shoulders of giants. From Faraday’s spinning magnets to Tesla’s vision of resonance, permanent‑magnet generators have matured into instruments of compassionate energy. Here, a slow-moving rotor infused with rare‑earth magnets aligns with precision-engineered stators to convert motion into a steady 50 Hz three-phase supply—all with minimal mechanical noise and vibration.

Imagine an aid worker in a remote village installing it alongside a windmill or mini hydro setup and when water or wind is not available the DC motor steps in to generate the output. Conventionally with such generators water turns the shaft and homes light up, refrigerators hum, and well pumps revive—without a single engine cough. That’s the calibre of silent perseverance this generator brings.

Customers say it best:

“Seems to power much more than it should.” — Rural Off‑Grid User
"Way better than an inverter, i think it's indestructible." — Van Dweller

With optimised efficiency and rugged build, this PMG endures damp and dust (IP54 rating), making it suitable even for outdoor mounting. Available in 110 V and 220 V options for battery-charging, or for mains integration, it adapts to your setup. The brushless design assures low maintenance, while a service life measured in decades promises continuity that matters.

Every component tells a story of quiet revolution—SKF-grade bearings, precision copper windings, cooled moulded-case housing—each part purposeful. The result? A generator that doesn’t dominate your soundscape but cultivates it, letting your home, cabin, or workshop resonate with calm pure silent sine-wave energy. No dirty noise in the power lines here! Just gentle oscillation of smooth energy.

Installation is intuitive: connect your power source, wire the output to your needs, and feel progress turn. No fuel required. No engine fumes. Just the pure physics of spin and magnetism, channelled into everyday use.

This is more than a generator—it is resonance incarnate. A pathfinder for communities, innovators, and dreamers who value electricity as much as strength. Harness its murmur, and step into a future where energy serves, responsibly, and always at your command.

The DC motor is 24V 500w 20A
The torque of a 500W 20A at 3000RPM is 15.9 Nm
Power output of generator is 150A-180A @ 50Hz
Tested running load 0.25w - 7Kw

Yes, the batteries can be connected to solar panels while the unit is in operation.
Yes, you can connect a 24V battery charger to a single-phase AC out put to propagate an extended battery charge, loads will need to be balanced with the other lines to increase efficiency.

The full 3-phase output can be connected straight to 3-phase machinery or to suitable high/low cost equipment; such as a 3-phase high capacity/voltage rectifier or controller, depending upon your application.

Schematics for converting the 3-phase supply into three separate single phase outputs is available post purchase at an additional cost.

Please also note that due to cost variance high-capacity voltage rectifiers and controllers are NOT included, but are not necessary to utilise and benefit from this machine.
