80v isn't too much
and how much Amps for all 4?
the one consume 7.5Amps

[jalessi]

The amperage requirement would be 2/3 of the total amp draw of the combined motors.

I would email the manufacture and confirm the suggested optimal power supply voltage.

Higher voltage will enhance the r.p.m. range of the motor.

what about this power supply https://www.omc-stepperonline.com/po...-s-350-60.html
i will use 4 of theme one for eatch stepper
am i right?

That is cutting it very close, I have no idea if durability will become an issue in the long run.
Have a most awesome New Year!

Yes

[habibmgh]

is it safe or not?
explain to me pls

[jalessi]

An ac power source "20~70VAC" is the stated manufacturer's specification 48 VAC is safe.

[jalessi]

Be extremely cautious connecting the power supplies in series since they are switching power supplies, many times they will not play well together.

The capacitors inside the power supplies most likely are not rated anywhere near 70 volts.

The electrolytic capacitors can explode violently if the operating voltage is exceeded!

Also If the commons of the power supplies are at ground potential it will not work.

I would not recommend doing so without a good understanding of such matters.
