You should be able to do that by turning the motor shaft by hand and measuring the back EMF. (Eagletree is sufficient to do this...)
And you need to check only one phase.
Count the number of zero crossings per one rotation and than the inverse of that will give you the minimum rpm. (1/# of zero crossings)
