power supply

Hi, everyone,
I'm building a 1m X 1m gantry for laser cutting, I'm using linear
guides from SBC for the y axis and fully suported round rails and
bearins for the X axis.
Transmition comes from 1" X 1" per turn ballscrews and a 4 to 1
drive belt system,encoders 400ppr(I've got most of it for free)top
speed should be about 350"/min.
Servo drives are on the way from Rutex.
I've got two engel servo motors rated at 52V,2.2 amps,3000 rpm and I
belive it's 17 amps max. I'll need a P.S to drive them, couls
someone enlight me on how many amps d I need on the P.S?
or the voltage and amps on the transformer?
or do any coments on how the P.S should be built.
Any help is welcome.

Thank's
Fogassa.
