Hi guys,
I'm trying to power 3 nema 23's and my setup is using 3 tb6600 drivers and one of these power supplies:
Can somebody please help me figure out what battery will work with this stuff?
Also, here's the datasheet for the nema 23's:
Thanks a lot guys, any explanation would be helpful, as I have very little idea about how voltage and amps and all that work.
That power supply converts 200 to 240 VAC from the AC mains to 24 VDC, where does the battery come in?
Whoa there, that link describes a 15 ohm bipolar motor? You almost certainly want a much lower impedance motor if you're running from 24V supply. Why such a high impedance stepper?? What's the application?
Normally a NEMA bipolar is about 1 to 2 ohm winding, 2 to 4A current rating, and a stepper driver will
buck-converter down to drive it giving lots of spare voltage for actually spinning the motor (the faster
it spins, the more voltage you require).
Steppers pull lots of power all the time, batteries aren't usually feasible for a stepper motor system.
Also a 15A supply is overkill, thats 120W available per motor.
Yikes. Problem is that I already have two of the steppers. Is it really something I should give up on?
I don't need them to run fast at all, but is their standing voltage itself too much?
Also... I'm guessing that the large power supply is why my motor is getting so hot.
Thanks for all the info.
For slow use they should work, 100 rpm or about that.
Steppers get hot, they run at full dissipation all the time.
Would something like this work then or would I need a 24 volt?
Basically I was put on a robotics project by a professor and bit off more than I could chew is the situation here.
Try it with a bench supply - if 12V is enough, you'll quickly find out!
