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
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.
