Coupling to the shaft of an electric motor (different size shafts)

You may find it easier to avoid the gear. Short splined shafts are stock items and can be purchased from PTO shaft and drive-line suppliers.

"Taper Lock" bushes are available for any diameter shaft. Google "Taper Lock".
There are several taper lock systems in different sizes available. Select a system that is bigger than either shaft to be joined. Then get two different bushes to fit the shafts.

There are also taper lock flexible couplings of different types.
Look at the taper lock HRC Couplings.

And there are bigger, more tolerant systems.

Hi. Could you help me with some advise on an electric shaft driven motor, the casing/shaft rods are too wide, can I get shorter ones to fit a 60v brushless motor? I’m a complete novice

Hi and welcome to PF. We need a lot more information about this before making any recommendations. A photo might help, showing the motor and were it's supposed to go. Some actual dimensions are needed.
