Help with motor and drivers wiring and setup

Thank you Paul,

That is my dilema. I dont know the speed (ppm) where the bipolar series drop above unipolar curve. If I can reach 5000mm/min with an aceptable torque, then maybe bipolar series is the best choice (at 48v). If that drop occurs at 500mm/min then is a problem and half coil is the answer.
Do you know the speed where bipolar series start to fail?

And in the case that use half coil configuration, the power supply can be 48v or I have to use 36v? The amp limit config in the driver, is 3A anyway or has to be lower?

To make things more clear, with your 6 wire motors and bipolar drivers you have only two possibilities. Bipolar series or half-coil.

With bipolar series you get better torque at very low speeds. It could be useful for a 4th rotating axis for example. Since in bipolar series the rated inductance will increase four times you will need a lot more voltage (than you have) for usable torque at higher speeds.

Since you need some decent speed for your 1 m travel, I think the half-coil is the better choice.

With the voltage you could go up to 20-25 times the rated voltage. If you are using unregulated PSU I would not go that close to the max. 50V.
In half-coil you need 3A and in bipolar series 2.1A. I think the rated current is RMS but I'm not sure.

Great Paul, clear like water. I buyed the wrong motors Lol.
Thank you, I will use a regulated power supply and half coil config as you recommend.
I can do the math with that info. I need to know what and why do what im doing.

Good night!
