20KW Air-cooled Or Water-cooled Permanent Magnet Generator PMG with 50Hz/60Hz Rated Frequency

The fundamental concept behind a permanent magnet generator revolves around the rotor containing permanent magnet materials that produce a steady magnetic field. This magnetic field remains constant as a result of the properties of the permanent magnets embedded within the rotor.

When a prime mover, which could be a wind turbine, water turbine, or engine, drives the rotor to spin, the magnetic field created by the rotor begins to rotate. This rotating magnetic field intersects with the conductors located in the stator windings surrounding the rotor.

Following the law of electromagnetic induction, the movement of the magnetic field through the stator conductors induces an electromotive force within the stator windings. When these windings are connected to an external electrical circuit, this induced electromotive force enables the generator to deliver electrical energy to the circuit.
