Hi,

I would like to measure the motor force constant (N/Arms) for my motor, what I did is using Beckhoff setup I measured the position and voltage for three phases. From the position I calculated the speed, and from the voltage I calculated the Vrms, then I fitted the speed and Vrms though a first order fit to find Befm Vrms/m/s and to find Bemf peak2peak I multiplied by sqrt(2), and to find the motor force constant I multiplied the Bemf peak2peak by sqrt(3/2). Is my approach correct?

Thank you  in advance
