Product Description
Permanent Magnet Generator Featuring Winding Material Y Pole Numbers 2-48 and NdFeB Magnet Type Optimized for Energy Conversion
Product Overview
A permanent magnet generator operates with a rotor equipped with permanent magnet materials that produce a steady magnetic field. As the rotor spins—driven by a prime mover such as a wind turbine, water turbine, or engine—the rotating magnetic field intersects with conductors in the stator windings.
Based on electromagnetic induction principles, this interaction induces an electromotive force (EMF) within the stator windings. When connected to an external circuit, this EMF delivers electrical energy to the external load.
Key Features
- Direct drive design with simple structure, no gearbox required, and brushless operation for enhanced reliability and reduced maintenance
- Exceptional efficiency exceeding 95% with power factor close to 1 for optimal performance and energy savings
- Nd-Fe-B permanent magnets supporting both clockwise and anticlockwise operation for versatile applications
- Capable of generating high voltage and power even at low speeds for efficient operation across diverse conditions
- Designed for durability with over 20-year lifespan and continuous 24/7/365 operation capability
- Customizable voltage, speed, power, and frequency options to meet specific requirements
- 3-year free warranty with lifelong service support for complete peace of mind
