Electrical Motor Shaft

It depends upon the original equipment manufacturer's [OEM] selection. Contact the OEM directly.

Carefull you will wear your fingers out typing so much.

more information please

You can make an electric motor shaft out of anything that can be formed into a cylinder. Steel, aluminum, copper, glass, wood, silicon, compressed grass clippings, butter, frozen concentrated orange juice, etc. etc. The issue is, only one of those is going to make sense if you want to do any useful work with said motor. The details beyond that are going to take a lot more investigation into the specifics of what you want to do, where you want to do it and how long you want it to last.

Now, any guess as to which one?

Most commonly used shaft material is EN8.In special cases where shaft is subjected to extra loading like Large fly wheel mounted or belt pull arrangement EN24 is used.These are most common.Of course there will be special applications which require special steel to be selected.Trust this answers your query.
