Summary

[edit]

Paraphrased article description:

A separately excited DC generator with bipolar field magnets. Separately excited generators like this are commonly used for large-scale power transmission plants. The smaller generator can be either a magneto with permanent field magnets or another self-excited generator.

From illustration caption:

Separately excited dynamo. Current for field excitation is supplied by a second and smaller generator.
