Aug 5, 2014 · Page 2 of 3 - Direct drive motor - posted in ATM, Optics and DIY Forum: I think it would work fine with a powertank, as long as the scope is well balanced and you dont rapid slew everywhere. I worked out the math and 3-5A would work for an 8 or 10 inch scope. When you are tracking at sidereal rate the power draw should be pretty small.

Motor options for a barn door tracker - Mounts - Cloudy Nights
Jun 17, 2013 · As I understand it, the steppers would require the most complex circuit, followed by the servo, and finally the DC motor. I know PWM would be needed to drive both the servo and the DC motor (for adjustable speed), but I am unsure of which would preform better. The required shaft rotation speed is about 0.9 RPM, so the motor speed should be 5-10 ...
