RE: Re: Power supply transformer setup questions...Capacitors

Jan,

That is VDC from the power supply?
Current (I) is the amperage sum of the motors * 2/3rds?

From what I read of the power supply pdf on geckodrives.com, that is what I
inferred.

A fair question. This formula came from Mariss, as I recall, and HE is a
sage. KNOWS his [stuff]. Me, I are a ignernt slob who only guesses "oh,
around
1000 µF per amp", ignoring voltage, except for "working volts" of cap.

But "V" in that formula with 80,000, I, and V is for POWER-SUPPLY volts, NOT

motor-volts. I think.
