What does it mean when a generator is motorized?

When a generator is described as motorized, it indicates that the generator is not actively producing electrical power, but it is still connected to a power source and sometimes functioning as a motor. This means that the generator is being driven or energized by an external power source rather than producing electrical energy from mechanical input.

In this state, the generator can be used to perform various tasks without supplying power to the electrical grid or load, such as providing excitation for synchronous generators. This condition is typical when maintenance is performed, or when testing is necessary without outputting energy.

Being "motorized" reflects this unique position where the generator operates without contributing active power to a load, illustrating a different aspect of its functionality.
