First of all, when we meet someone new,we usually introduce ourself. We say ‘My name is …’
This time I write self-introduction. It’s a very easy-to-understand expression.
1. My name is TOM.

W a -ta- shi -no- na -ma-e-ha-tom- desu
More slowly…
*Meaning
My ( wa -ta- shi -no) = My
Name ( na -ma-e) = name
Is … (Ha ~ de- su ) = is
TOM = TOM
Or it may just be a simple saying your name.
2. I’m TOM.

W a -ta- shi -ha-TOM-de- su
More slowly…
*Meaning
I ( wa -ta- shi ) = I
Is (ha ~ de- su ) = am
TOM = TOM
If any question, please leave your comment.
Let’s try.
