synchronous generator

A synchronous generator is a machine that converts mechanical energy into electricity. It operates by maintaining a constant magnetic field and an armature that receives or delivers alternating current in sync with the machine's motion. These generators are crucial for power networks, producing alternating current with a fixed frequency, typically 50 or 60 cycles per second.12

The mechanical power is usually supplied by a rotating shaft, driven by sources like hydraulic turbines, wind turbines, steam turbines, or engines. Inside the generator, a rotating magnetic field, produced by conductors on the rotor, induces a voltage in the stator coils. This induced voltage follows a sine wave pattern, which is ideal for power transmission and distribution due to its compatibility with transformers. Synchronous generators are designed to produce this precise waveform, ensuring efficient and stable electricity supply.2
