i've already been using this Granger motor (DAYTON - DC Gearmotor 12VDC Nameplate RPM 17 Max. Torque 30.0 in.-lb. It also lists it as being only 1.4 full load Amps.) for a while with a LED and circuit board to track the sun for our solar parabolic hot water heater project (http://www.appropedia.org/Parabolic_Solar_Hot_Water_Heater), but since the LEDs were getting confused by stray reflections and we were going to use the Raspi B for temp readings, we decided to try and adapt Jay Dosher's (https://github.com/polyideas/Raspbe...r/Software (File System Root)/usr/lib/cgi-bin) program to Python 3.x. We had a bear of a time, since we're not programmers, but we finally got this phase finished - well except for calibrating the IMU sections of the new program. However we decided to set that aside and begin work on the type of motor we'd need, since we were told that our simple Dayton DC gearmotor would not do with our new setup and an IMU.
So we set about looking for a comparable motor to the Granger - and since we're not engineers - we decided that the most important part of the motor setup would be related to how much torque the motors produced. We saw that the Granger apparently produces about 30 in. lbs. and looked up the nearest Nema which apparently produces about 24. However the Nema requires almost double the amps of the Granger (actually it's a Dayton motor) and so, we're asking for help in this forum to figure out which stepper we really need and if our puny L298N H-Bridge will handle it.
Have a great afternoon!
