Do you know the structure and function of permanent magnet generators?

The generator is the core equipment that converts mechanical energy into electrical energy. Permanent magnet direct drive wind turbines use generators, which have the advantages of simple structure, high efficiency, and low maintenance.

The structure of a permanent magnet direct drive generator mainly consists of a stator, rotor, casing, cooling system, etc.

Stator: The stator consists of an iron core, windings, and slots, used to generate induced electromotive force.

Rotor: The rotor consists of permanent magnets, magnetic yokes, and shafts, used to generate a magnetic field.

Chassis: The function of the chassis is to support the stator and rotor, and protect internal components from external environmental influences.

Cooling system: The cooling system is used to dissipate the heat generated by the internal components of the generator, ensuring that the generator maintains a suitable working temperature during long-term operation.
