Transformer selection

Ok,

I think I wasn't too clear.

I meant 120-120 primary (240) to DC voltage of 120 volts
with enough power to run 4 servos that could draw up to
10 amps each ,probably would never happen though.

The servo amplifiers I have can handle a much higher voltage
than 120 , but the motors can't.

I am thinking I could get away with the transformer I found
and have more power than I would ever need ????

Feed rates and rapids are what is going to control the voltages
that are put to the motors ?? Correct ? So as long as I dont exceed
the speed the motors should never see the higher voltage ??

Or just tell me what kind of transformer I should be looking for :-)
One big one or two smaller.....

Thanks
Tim
