6 Geckodrives with 2 Rectifier Set Up?

[Sunmixed]

Hello everyone,

I would like to try a 6 axis setup, 2x Nema34 1800 Oz/In Stepper Motors, and 4x Nema34 1200 oz/in stepper motors, all from keling, as well as 6 Geckodrives.

There is not really an application for such set up, just being curious how I should wire it up.

The Rectifiers i'm using is a Bulky Block 35A Rectifier, where i guess it is good enough to supply up to 3 motors per Rectifier. If I use another Rectifier to cater the another 3 motors, is it really recommended?

What i'm concerned about is each rectifier made has its tolerance where the AC to DC conversion may not be as accurate as AC/0.707 = DC, which will result in DIFFERENT MOTOR PERFORMANCE, in terms of Speed (V) and Torque(A).

Does it really matter? or not? Thank you guys.

Charles

You have the formulae backwards, ACx1.414 = DC.
The characteristics of most silicon rectifiers is voltage across the junction will increase with current, from av. of .6v min I to 1.2v at max. rated I.
Don't forget there is two in series in a bridge configuration.
Consult the manufacturers spec for the actual numbers.
