If you hooked up 24vdc I doubt if it would spin if it was brushless, unless you have a BLDC driver amp. If it was straight DC then it was most certainly brushed, two ways of determining voltage required is to estimate the maxium rpm, for a brushed motor, it rarely goes over 3000 unless a specialty.
so you can either apply a voltage and measure the rpm, it will be directly related to speed, so if 24vdc gives you 1000 rpm then it is roughly a 75vdc motor.
Or you can spin it a known rpm and measure the generated DC, and do the same math.
If you need any other specs, I think I have a previous post on finding them emirically.
