Product Description
AC Current Type Free Energy Solutions Including 2 to 48 Poles Supporting Advanced Power Conversion and Energy Efficiency
Product Overview
The fundamental concept behind a permanent magnet generator is that its rotor is equipped with permanent magnet materials, which create a steady magnetic field. This magnetic field remains constant as opposed to being electromagnetically induced.
When an external power source, such as a wind turbine, water turbine, or engine, causes the rotor to spin, the rotating magnetic field interacts with the stator windings. As the magnetic field moves relative to the stationary conductors in the stator, it effectively cuts through them.
Based on the law of electromagnetic induction, this motion induces an electromotive force within the stator windings. When a load or external circuit is connected to the generator, this induced electromotive force drives an electrical current, thus producing usable electrical energy.
