Hi all!

I want to drive 4 motors for a project.

3 are this nema23 ( www.oyostepper.com/goods-65-Nema-23-Step...res.html23HS16-0884S ):

1 is this nema34 ( www.oyostepper.com/goods-101-Dual-Shaft-...4mm.html34HS46-5004D ) :

The 3 drivers for nema23 ( www.oyostepper.com/goods-117-Nema-23-Ste...step-M542T.htmlM542T ):


and the driver for the nema34 is this (DM556):

My question is: wich power supply do i need for the four drivers?
Current in my country is 220V

Thanks in advance!

Any 24VDC @ 10A should do.

The specifications specify 5 volt and 6.6 volt. The largest current is 5 amp. A power supply of the standard value of 6 volt and 6 amp or more will do. 24 volt is incorrect

Stepper motors can run on a lower voltage. They have then less power. Much more then rated is not recommended. Just read the specification.

...but your not powering the steppers directly, you are powering the driver boards, which are both 24VDC input! 10a gives a little head room.

So 24V is correct.

The driver card can control stepper motors within this range:

Driving Voltage(V) 24 - 50
Output Current(A) 1.5 - 4.5


How does this match with a stepper motor with the specification 6.6 volt 5 amp?

Both boards will work with a "standard" 24VDC INPUT VOLTAGE, so a 24VDC power supply is one part of the equation. The next is how much total power (P=VI) is required for the steppers, so I just added up each power rating plus a bit and got to 10 amps (this is only for the steppers mentioned, and would not allow the drivers to be used in parallel to their maximum rated load which would be approximately 458W).

One of the drivers is rated to 4.5a and the other to 5.6a maximum output (but as I said, the steppers don't need anywhere near that amount individually).

It is probably cheaper to get a 24VDC @ 15A than 10A, there seems to be a lot more choice. (If you want to push the drivers to their max rated load you will need approximately 24V@20A supply)

So 24VDC @ 10A should do as required, but 24VDC@20A will allow the drivers to run at 100% rated load.

If the motors are rated for 5 volt or 6.6 volt 5amp what will happen if you supply them with 24 volt?

Okay looks like you can apply a higher voltage since the current will rise delayed due to the inductivity of the coil. Then 24 volt will work.
