Re: Higher voltage servo motors with low volt drivers

Thank you for all who tried to answer my thread you've been more than
helpful.
As I understood from Jon Elson's reply, I will not loose any torque if I go
with Gecko320, and the only thing I will be sacrificing is speed, which is
not crucial in this stage for me.
So any suggestions for the DC power supply if I go with Gecko320???
