Now, I'm slightly confused about whether these two components work together with respect to their polarity (unipolar vs. bipolar?) as well as the power supply (I'm currently powering with 12v 1000mA). At the same time, the stepper motor website recommends me a specific shield for the motor (1067_0B Phidget Stepper Bipolar HC).
Could anybody help me and give me some advice?
Many many thanks!
For that stepper I would recommend the A4988 or DRV8825 drivers. The linked motor driver uses ancient and very inefficient technology. The DRV8825 will handle a bit more current than the A4988 but for your motor, either will do. Be sure to read the page for the driver to see how to set motor current, It is very important that the setting be done properly. The linked motor driver costs about 50 times the cost of a A4988 or DRV8825 and will do no better of a job when used with an Arduino.
Your power supply should be OK as the motor coil current is speced at 670mA.
Thanks so much for your reply! Unfortunately, I already ordered the motor shield and motor already. do you think I will get it running with the setup I mentioned (Even though not super efficient)?
many thanks!
Yes, you probably can get it "working", but you will not have the current control, microsteppeing and other features of the modern drivers. Also, You are operating the motor shield at the edge of its current specification and the L293 driver chip drops over 2.5 volts at 600mA so your motors will see only 9.5V.
My recommendation is to order the better drivers and junk the L293 based shield. The A4988 and DRV8825 drivers are available for less money (than Pololu) on Ebay. I linked the Pololu pages because they have lots of information on the use of the drivers.
Did you look at the stepper basics tutorial that I linked? Did you look at the Pololu page that I linked? That page has information on connecting the driver to a Arduino.
so I'm slightly dependent on short lead times. What do you think about these guys here?
