Hi so I posted in here the other week about motor gear ratios etc.

I thought I had done all the calculations from the data sheet provided however I just got an email from a tutor stating that I will need to characterise the motor and get the volts per amp of the motor.

This is confusing me, Is there anything missing from the calculations I made or from the data sheet,

The original thread is here by the way, I made a new one as people might want to search for motor characterisation and miss out on this thread.

Thanks for any help.
