TMS320F28027F: Identify Motor Parameter

Part Number: TMS320F28027F

Dear Champs,

Q1: InstaSpin provide a good way of identifying motor parameter, I would like to use this for compressor(air conditional system). In most cases, the compressor is assembled in system already, that means the compressor is not light load, and sometime it is in a full load in worst cases. Does the identifying feature still be work with load?

Q2: I found the back-emf constant provide in some of motor spec are Vrms/krpm, but instaspin require VpeaK/krpm, if I just use equation, Vpeak = Vrms*sqrt(2), is it correct?
