Re: [CAD_CAM_EDM_DRO] Servos, Drivers etc.

Hello,

While gecko's will not run them at their max revs, they will be able to
produce their max torque. These are very powerful motors, just take into
account the max revs you will get with around 80v when you are deciding on
your reduction.

Its really a matter of how fast you want to go.

Rutex do offer a 200v version, but remember the requirements for your
powersupply change going to the extra 40v.

Just a note, I can supply these motors for US$150ea + shipping, which is
from Australia so its probably cheaper to buy them on your end.

Regards,

Jason Cox.
