V/RPM to V/(rad/s) in electrical radians conversion
V/RPM to V/(rad/s) in electrical radians conversion
(OP)
If Ke = V/RPM, converting to mechanical radians would be: 60s/(2*pi radians) =9.55V/(rad/s).
Converting to electrical radians: we would multiply the above by (pole pairs * radians mech) / (radians elec).
Thus converting V/RPM directly to electrical radians would be: : (pole pairs * 60s)/(2*pi radians)=57.2V/(rad/s). Is this correct?

RE: V/RPM to V/(rad/s) in electrical radians conversion
forget pole count - has no meaning here. have u ever heard of a motor Kb rated in v/krpm per pole pair? nope. it is v/1000rpm -- where the r in rpm is a rev of the motor shaft. so pole count has nothing to do with it.
so yes, v/rpm is indeed simply convert minute into seconds & convert a motor revolution into 2pi radians.
dont forget that most Kb ratings are in v/Krpm so take that 1000 into account too.
