1kW 12V PMA Permanent Magnet Alternator Brushless Low-RPM Generator
1200W 12V PMA Permanent Magnet Alternator — Synchronous Generator
Powerful, compact 12V charging and lighting alternator designed for low-RPM use. Built-in rectifier and stabilizer simplify wiring and provide steady DC output. ⚡🔋
Key Features
- Permanent magnet synchronous design: Built for stable low-RPM AC generation and DC output.
- Integrated silicon rectifier & stabilizer: Internal full-wave rectification reduces external parts needed.
- Pure copper windings: Improved conductivity and heat resistance.
- Dual-purpose: Charging and lighting at 12V (peak ≈ 14V).
- Compact aluminum shell: Lightweight body with straightforward mounting dimensions for easy installation.
This PMA alternator pairs a magnetic-strip rotor with an internal full-wave silicon rectifier and a voltage stabilizer to deliver reliable low-RPM charging and lighting. Installation is simple: connect battery positive to the generator’s “+” terminal via a switched live wire and ground the negative to the chassis. Built-in rectification and stabilization help simplify wiring. 😊🔧
