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.
