China Free Energy Magnet Generator
The China Free Energy Magnet Generator from Shanghai United Metal Materials is a permanent magnet-based electrical generator constructed with sintered NdFeB magnets, copper windings, and a steel housing. It produces electrical output through magnetic flux conversion, with no external power input required during operation. The unit is designed for low-power applications and operates efficiently at rotational speeds between 500 and 3000 RPM, depending on magnet array configuration and coil winding density.
The generator uses sintered neodymium-iron-boron magnets with a maximum energy product of 48 MGOe, typical for industrial-grade permanent magnets in small-scale generation systems. Copper windings are insulated with class H enamel, offering thermal stability up to 180°C. The steel housing provides magnetic shielding and mechanical protection, with surface finishes matching standard industrial corrosion resistance practices. These materials align with common industry practices for experimental and off-grid power prototypes, though no formal efficiency certification is provided by the supplier.
This generator is primarily sourced by educational institutions, DIY innovators, and small-scale renewable energy developers seeking to test magnet-based power generation concepts. Buyers commonly integrate it into wind turbine prototypes or hybrid off-grid systems. Packaging is standard industrial carton with foam internal support. Trade terms are typically FOB Shanghai, with MOQ and lead time confirmed directly with the supplier. No pre-installed voltage regulation or rectification circuitry is included.
| Magnet Material | Sintered NdFeB (Neodymium-Iron-Boron), grade N48 |
| Magnet Shape | Arc segment, typical for radial flux array in small generators |
| Winding Material | Enameled copper wire, class H insulation |
| Housing Material | Low-carbon steel, powder-coated for corrosion resistance |
| Operating Temperature Range | Typical operating range: -40°C to +150°C, magnet demagnetization threshold at +175°C |
| Output Voltage Range | Typical open-circuit voltage: 12V to 48V DC, dependent on RPM and coil turns |
| Maximum RPM | 3000 RPM, beyond which mechanical stress may exceed design limits |
| Weight | Approximately 4.2 kg, typical for a 100W-class permanent magnet generator |
| Protection Rating | IP54 standard for dust and splash resistance, typical for industrial prototypes |
| Magnet Surface Treatment | Nickel plating, standard for NdFeB magnets to prevent oxidation |
Shanghai United Metal Materials is a manufacturer and supplier of permanent magnet materials and magnet-based components based in Shanghai, China. The company specializes in sintered and bonded NdFeB, ferrites, SmCo, and AlNiCo magnets, with production capabilities including machining, coating, and assembly. The supplier’s profile indicates active participation in B2B export channels and direct engagement with industrial buyers, though no company history, workforce size, or certifications are disclosed in the listing.
The supplier does not claim ISO certification, revenue figures, or client names. Their trust tier is classified as 'harbor', indicating basic verification of business registration and contact details. Response rate and average response time are not available, suggesting limited or automated buyer communication. The listing focuses on material supply rather than finished product manufacturing, implying this generator may be assembled from in-house magnet components rather than fully produced in-house.
This permanent magnet generator utilizes high-grade NdFeB magnets to convert magnetic flux into electrical output, suitable for small-scale wind turbine applications, educational prototypes, and DIY free energy projects. Designed for export and OEM supply, the unit features robust construction with sintered neodymium magnet arrays and copper windings. Ideal for B2B buyers seeking magnet-based power generation solutions for off-grid, industrial, and research applications worldwide.

Sourcing China Free Energy Magnet Generator from Shanghai United Metal Materials - China Import Guide
Before ordering, verify the magnet grade and coil winding specifications with the supplier. Request a magnet test report showing Br, Hci, and BHmax values, as performance varies significantly between N35, N42, and N48 grades. Confirm the air gap tolerance and rotor balance specifications, as mechanical misalignment reduces efficiency. Do not assume the generator includes rectifiers or regulators unless explicitly stated.
Lead time is typically 15 to 30 days after order confirmation, but must be confirmed directly with the supplier. Standard Incoterms are FOB Shanghai, with payment usually via T/T 30% deposit and 70% against shipping documents. Packaging is standard industrial carton, but buyers should request custom packaging if shipping to high-humidity regions. Export documentation includes commercial invoice, packing list, and bill of lading.
Quality checks should include visual inspection for magnet chipping, winding insulation integrity, and housing weld quality. Request a no-load voltage test at 1000 RPM and a short-circuit current reading to validate output consistency. Buyers should also request a magnetic field map if integrating into a wind turbine system. Documentation should include material certifications for NdFeB and copper, though supplier-provided certificates are not guaranteed.
