Product Description
Rare Earth NdFeB Multi-Pole Coreless Permanent Magnet Generator 3KW 5KW 10KW
Advanced Rare Earth Permanent Magnet Technology
The coreless permanent magnet generator utilizes premium NdFeB rare earth permanent magnets in a multi-pole rotor configuration. Combined with a small air gap design, this generator delivers exceptional power density and large output power for demanding renewable energy applications.
Key Technology Features
- Rare Earth NdFeB Permanent Magnet: High-grade neodymium magnets (N38SH-N45H) provide superior magnetic field strength and long-term stability
- Multi-Pole Rotor Design: Increased pole count enables higher frequency output at low rotational speeds
- Small Air Gap Construction: Precision-engineered air gap minimizes magnetic flux leakage for maximum energy conversion
- High Power Density: Compact design achieving industry-leading power-to-volume and power-to-weight ratios
- Low Start Torque <0.1N.M: No hysteresis and gear notches effect enables ultra-easy startup in light wind conditions
Coreless Design Advantages
- No iron core eliminates cogging torque and mechanical resistance energy loss
- "Precise Coil" technology ensures optimal electromagnetic performance
- High efficiency above 85% across the operating range
- Gearless direct drive eliminates transmission losses and reduces maintenance
- Brush-less construction with no wearing parts for extended service life
Applications
- Vertical Axis Wind Turbines (VAWT)
- Horizontal Axis Wind Turbines (HAWT)
- Hydro power generation systems
- Off-grid and hybrid renewable energy systems
Quality Assurance: CE and ISO 9001:2015 certified. Backed by 3 years warranty.
