Hi. Can someone recommend a power supply to use for my stepper motor? I tried to test it with a 9V battery and I was told that was foolish. I would like to run it off several AA or C batteries, or a rechargeable lithium ion pack.
I am using a NEMA17 Bipolar Stepper Motor, it's rated voltage is 2V-36V, it's rated current is 1.2A My driver is the DRV8834 Low-Voltage Stepper Motor Driver Carrier which operates at 2.5–10.8 V and can deliver up to approximately 1.5 A per phase continuously without a heat sink or forced air flow (up to 2 A peak).
Ultimately I want to power this motor for 12-24+ hours on one charge or set of batteries, but it will only be doing one step every 1-15 minutes, so it won't be running at full speed the whole time. Right now I'd just like to get it running so I can start writing my program and testing it though.
