I’m a beginner in electronics and arduino. I shouldn’t propably working on an advanced project at the begining of my journey but I prefer to work on something I’m interested in. Back to my project, I need a stepper motor (high torque = > 20 Kg-cm) to pull a rope (1.5m long) around a pulley. I also want to make it work with a battery and of course control it with arduino. What kind or power motor should I use? Do I need a stepper controller, other than arduino, also? Furthermore, the mechanism should be kept in a low weight. After a short search I came across to:
http://www.futurehouse.gr/index.php?main_page=product_info&cPath=50_67&products_id=342 (57BYG621 NEMA-23 Bipolar 76mm Stepper)
with controller http://www.phidgets.com/products.php?product_id=1063 (1063 - PhidgetStepper Bipolar 1-Motor)
http://www.futurehouse.gr/index.php?main_page=product_info&cPath=50_67&products_id=345 (42BTGHW811-AG5.18 NEMA-17 Bipolar 5.18:1 Planetary Gearbox Stepper)
with the same controller (1063 - PhidgetStepper Bipolar 1-Motor)
What is your suggestion? What kind of parts do I need? Is there any example code close to my project? Is it possible to pull such weight with a battery <= 12V?
Thank you in advance…
