Running a 12V motor at 8.4V?

Hello,

I’ve been using the Lynxmotion 7.2V gearhead motors with encoders with a lot of success running off an 8.4V NiMH battery pack. Now I need a second set of motors for another robot but I see that only 12V versions of the motor (with encoders) are available–for example, the GHM-15:

My question is: can I run a 12V motor like the GHM-15 off an 8.4V battery pack? In other words, will it simply not run, or will it run at a reduced top speed and torque?

Thanks!

Reduced speed and tourque.

Great–thanks for the reply!
