How to test a servo motor without servo drive?

I am doing a retrofit and I recieved my servo motors but I am still
waiting for drives from Rutex. I would like to test the motors now
and I am wondering if there is an easy way to do that without risk of
damaging the motor?

My guess is that a constant DC level will work but I would imagine
that I would have to limit the current. It seems too simple to use
ohms law and put in a series resistor?


Thanks,

John
