Generator Overview
Our Permanent Magnet Generator (PMG) is specifically engineered for vertical axis wind turbines (VAWT), offering superior performance in low to medium wind speed conditions. With a high-efficiency design and robust construction, this generator ensures reliable energy conversion, minimal maintenance, and long-term durability in both on-grid and off-grid wind power systems.

Internal Components

Designed with high-grade neodymium magnets and low-loss copper windings, achieving up to 92% efficiency at rated RPM, even in turbulent wind flows typical of VAWT operation.

Generator Body Features
  • High-grade Neodymium Iron Boron permanent magnets
  • Each magnet tested for magnetic flux by authorized institutions
  • Engineered for low starting torque requirements
  • High generating efficiency through optimized internal structure
  • Robust construction for long-term reliability

  Operates effectively at low rotational speeds (from 50 RPM), making it ideal for VAWTs which often start generating at lower wind speeds compared to horizontal axis turbines.

  Fully sealed housing with IP54 protection against dust and moisture, suitable for harsh outdoor environments. Precision-balanced rotor for reduced vibration and noise.

  Built-in thermal management with high-temperature resistant insulation (Class H), ensuring stable performance from -30°C to 80°C.

 Compatible with most VAWT designs (Darrieus, Savonius, or hybrid types). Options for direct drive or gearbox coupling, with customizable mounting configurations.

Wheel Hub & Connectors
Precision-engineered steel wheel hub connects blades to generator with durable blade connectors constructed from Q235 plate featuring anti-corrosion surface treatment for extended performance life.
