For the development of a new motor which delivers 100-kW peak for a weight of 8 kg (185mm diameter axial flux motor), we are considering different choices for voltage / rpm.

As you know, voltage relates to rpm and this motor will deliver 100-kW peak (50-kW nominal) at 12.000 rpm. For the voltage we have choices (no of turns in the windings). What is the battery voltage you would expect at 6000 rpm and at 12000 rpm?

I presume their is a difference for the DIY or professional market.

Thanks in advance!
