eBay eBay DIY Disc Generator Coreless Generator Permanent Magnet Low Speed High Efficiency Wind Power Hydraulic The disc-type core-less generator is composed of two parts, the rotor and the stator. It is a double-rotor structure, and the stator armature is placed in the middle of the double-grasping rotor to form a double-air gap structure with the stator.As long as the stator design is reasonable and the manufacturing is accurate, the magnetic tension of the rotor on both sides of the rotor can be balanced with each other during operation, so that the bearing is not subject to axial force and the service life of the motor can be extended. The magnetic steel is directly bonded to the rotor.The windings of the motor have no groove and no core structure, which can reduce the electromagnetic torque ripple caused by the tooth groove effect and bring many disadvantages caused by the core.Moreover, because the armature winding has no iron core, the magnetic circuit does not exist the saturation problem, the calorific value reduces, causes the motor mass to reduce, the loss is low, the efficiency increases.Because there is no magnetoresistance problem without iron core, it has the advantages of low start resistance torque, high power density and smooth operation at low speed. Its dynamic performance is very superior, which is very suitable for direct drive wind power generation with low wind speed, and it can realize light wind starting and light wind power generation.It is also well suited to areas where free energy requires high efficiency. Size: 185 x185 Generator shaft: 20mm /12mm Generator rotor: 12 pairs of magnetic stages, 150mm Generator coil: 9 coils, wire diameter 1.18mm Generator power: 1000w Generator speed: 120-1500 Generator voltage: 1-100v Generator current: 1-35a Torque: 7 Nm Generator shell is divided into two kinds, acrylic and steel plate, acrylic crystal clear, good-looking appearance, relatively high strength of the steel plate, according to their choice. From June 1, the generator has replaced the transparent coil coil with a white coil coil instead of a 12mm shaft and 20mm diameter.
This generator is a game-changer for DIY wind power projects! The coreless design and double-rotor structure deliver impressive efficiency even at low speeds. I was amazed by how smoothly it performs—perfect for small-scale renewable energy setups. The build quality feels solid, and it's surprisingly easy to install. If you're into sustainable energy, this is a fantastic investment that actually delivers on its promises. Highly recommend for hobbyists and eco-conscious users!
