... just looking at the reference link:
https://en.m.wikipedia.org/wiki/Motor_constants
where the constant Kv is described, it looks like the basic problem is to obtain an accurate voltage measurement directly at the stator coils, as the motor is operated at the maximum no-load RPM. ... A scope measurement might be appropriate here.
... maybe include the units that are required for your measurement.
