Hi Henrique Pinto,
有名,著名 and 闻名 are synonyms and they all describes the fame. But there is still a little difference.
◎ 有名, yǒu míng, well-known
有名 emphasizes on the name is known to everybody, sometimes 有名=出名.
For example:
He is very famous in this area.
他在这一带很有名。
◎ 著名, zhù míng, famous
著名 emphasizes on prominent and outstanding people. Sometimes it is used to describe a person, a city or a war. etc
For example:
He is a notable person.
他是一位著名人士。
◎ 闻名,wén míng,renowned
闻名 emphasizes on widely known by people. It can be used to describe people or things. 闻名 is often used together with 举世 to constitute a set phrase “举世闻名”。
For example:
The Great Wall is the world-famous historic building.
长城是举世闻名的古建筑。
I hope these answers can be helpful for you to understand these phrase.
