Generator vs. Dynamo: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 20, 2023
A generator is a machine that converts mechanical energy into electrical energy, while a dynamo is a specific type of generator that produces direct current.

Key Differences

A generator is a broad term for devices that convert mechanical energy to electrical energy. It encompasses various types, including alternators and dynamos. A dynamo, specifically, is an early type of generator that produces direct current (DC) using a commutator.

Generators work on the principle of electromagnetic induction, where a varying magnetic field induces an electric current in a conductor. Dynamos, being a subset of generators, operate on the same principle but are designed for producing DC power through the use of a commutator.

The term dynamo has historical significance, being one of the first electrical generators used for power generation and distribution. Generators, as a broader category, have evolved to include more efficient and diverse types, like alternators, which produce alternating current (AC).
