loking for help with power supply for rutex drives...

i want to build or buy a power supply for rutex drives. i want to
use three of them to power three 3/4 hp micro 100 dc brush servo
motors on my old knee mill.

i'm not sure which drive are best fitted to my motors, but i'm
leaning towards the R90H (200V/40A). there are two other sizes
available that i can use if i can find the right power supply for
them. R990H2 (200V/10A) or R990H (100V/20A)

if i'm to build one,i need help to select the appropriate components,
as i am a machinist, and not an engineer. can anyone reccomend which
components i would need and where to find them? what va rating for
the transformer? what type of rectifier? what kind of capacitor or
filter? any schematics for this?

or can anyone possibly reccomend where i can buy a power supply?...
just got the motors, can't wait to get this up and running!

my motor info is as follows:
Nema 42 Face mount with 5/8" output shaft

> 120 Volt Nominal Terminal Voltage Rating
> Torque constant: 5.75 Lb-In/Amp
> Cont Torque Rating: 34 Lb-In
> Peak Torque: 150 Lb-In
> Weight: 14 lbs
> It is rated for up to 120 Volts, 5.8 amps.
> The motor's back-emf constant is 68.6 Volts/kRPM...so,
> The motor will run 15 RPM for every volt you give it.
> For example, on a 48 volt supply, you could expect 700 RPM for a no-

load
