VQP’s permanent magnet alternator is designed to provide up to 1200W with an AC output in the 12V–14V range, optimized for low RPM operation. The generator is built to work across various platforms such as agricultural vehicles, wind turbines, and other power systems requiring stable charging and lighting. A built-in voltage stabilizer helps maintain a consistent output, protecting connected devices from voltage fluctuations. The combination of PMA technology and stabilization makes this unit versatile for off-grid setups or mobile power applications.
Low RPM PM Generator with 12V Output
This model mirrors the same high-stability performance found in other low-speed PM generators. It uses NdFeB magnets and quality copper windings to achieve efficient energy conversion at reduced wind speeds. The housing is a die-cast aluminum cover, offering robust wind resistance and long service life due to corrosion-resistant treatment. With a direct-drive, gearless configuration, it is straightforward to install and operate, appealing to hobbyists and professional installers alike.
Low RPM PM Generator for 48V Systems
This variant targets mid-to-high voltage needs, compatible with 48V configurations while maintaining low RPM efficiency and robust performance. Its NdFeB-based magnet system and copper windings provide stable efficiency across a range of wind speeds. The die-cast aluminum housing ensures durability in challenging environments, and the corrosion-resistant coating extends lifespan. Gearless, direct-drive operation supports simple maintenance and reliable power output for small-scale off-grid projects and hybrid energy systems.
EODSAD PMA with Built-In Stabilizer
EODSAD’s Permanent Magnet Synchronous Generator combines an excitation silicon rectifier with a permanent magnet constant voltage alternator. The magnetic strip rotor plus a built-in full-wave voltage stabilizer reduces costs while enhancing overall power. The design supports dual-purpose charging and lighting, making it suitable for off-grid farms, remote cabins, or small workshops seeking dependable renewable power with straightforward integration into existing systems.
Buying Guide
- Voltage and voltage range: Choose a unit whose output voltage aligns with your battery bank or load. Many options support 12V, 24V, and 48V systems, while some offer AC outputs with stabilizers for broader use.
- RPM compatibility: Low RPM or gearless PMA designs perform better with light-wind situations and require less maintenance than gear-driven systems.
