Still trying to learn the details of how to choose Motor Controllers depending on the Stepper.
I've got two different Bipolar Stepper Motors:
1: (NEMA 17 / 200 steps/rev)
Current: 1A/phase Phase Resistance:3.5Ω Holding Torque:13 Ncm (18.4oz.in)
2: (NEMA 23 / 200 steps/rev)
Current: 3A/phase Phase Resistance:1.12Ω Holding Torque:190 Ncm (1.9Nm / 269oz.in)
What motor controllers would be most appropriate and why?
for #1, from what I can tell, the following would be fine: - L298N (Oldest / least efficient, but should work) - TB6612FNG (Peferable because it's MOSFET) - A4988 (Takes over the stepping controls from the MCU. Is it MOSFET?)
What would be best options for #2?
I understand the stepper motors deliver better performance at considerably higher voltages than the typical listed on in the spec sheets (approx 3ishV listed for the above). I've seen numbers suggesting 12v, 24v, even higher.
a) Does operating motor controllers at higher voltages raise the amps such that you have to re-consider your choice of motor controller? b) How to determine how high to take the voltage?
