Information needed on Faulhaber Motor- low Rpm

I need a Brushless DC motor with a RPM as low as about 120 RPM and torque as 80 mNm.

I tried to explore the Faulhaber motors. I didn't get any motor meeting my requirements. I got a Faulhaber Motor which, if operated at 3 V, will meet the requirements I have but the problem is that its nominal voltage is mentioned as 48 V.

My question is: Is it appropriate to use a motor with nominal voltage as 48 V, at the voltage value of 3 V, continuously for hours. In the manual for that motor, they clearly didn't mention any lower limit anywhere. They gave a limit only on the maximum value.
