Review: Motorized Blinds - I’ve seen others who have been interested in motorizing their Coolaroo Roller Shades. Well, I wanted that to so I figured out a ‘fairly’ easy way to do it. I’ve included a picture of the configuration and a video of the movement. The parts are: 12v 80rpm Reversing Motor B07F8S57JT , 8mm Flange Coupling B0822425TT , Motor Mounting Bracket B073NZ81M9 , 12V Momentary Rocker Switch (DPDT) Reverse Polarity B0885W19KL , and a 12v ~10amp Power Supply. It will take some playing around to get it all put together, but getting the right pieces was the hardest part. I didn’t play around with trying to get a controller that would have stopping points. Just one more thing to break. So, with this it’s manual stopping points controlled by removing your finger from the switch. I mounted my configuration to a backing board. This allowed me to get it all setup before mounting it. The motor end has to be elevated a little bit to get the roller parallel to the backing board. The non-motor end is just the clip-in end that comes with the Coolaroo blind. Instructions: Take the black plastic end off of the blind that will be attached to the motor end. Attach the flange coupling to that end. I had to make some modifications to the interior of the tube to make room for the small nuts and screw ends I used to attach the coupling. Figure out where the motor needs to be mounted. Once the motor is mounted you can slide on the coupling end on to the motor, lock it in place and snap the other end into the clip-in Coolaroo end. Search for “reverse polarity wiring diagram” in order to see how to wire the switch. For my testing and video I used a weak (1.5 amp) power supply. Using a 5-10amp supply should provide a little more umph. I experimented with a 6’ wide blind. I don’t believe the motor I used would handle anything bigger. It just wouldn’t have enough torque. Mine will be hung on the outside of the window. I’ll need to get wires into the house and figure out where I want the switch. I’m thinking of just embedding it in the molding on the inside of the window. __________ Up for 2 years and working well.
Review: Strong Motor and Gearing - Great mini motor has plenty of torque for what I needed it for and the self-locking in place works very well.

## Questions & Answers

**Q: Will it work with ac adapter 12v 3.0 a?**
A: This is a DC motor. So the input voltage must be DC voltage. AC volatge can not work. This motor needs DC 12V volatge to work normally.

**Q: Is this motor strong enough for an electric wheelchair?**
A: strong enough yes but i don't think it would last very long. plus it is very slow, 12 revolutions per minute . i would want my wheelchair to be a lot faster than that.

**Q: Will these work for combat robot**
A: I'm not sure. It has lots of torque. At 16rpm, I'm not sure if it is fast enough for the combat you have in mind. Also, I have not used it enough to determine how reliable or durable it is. The same manufacturer has 32rpm and higher versions. I would buy one of each and test them. I'm pleased with it so far. I've purchased 4 of them.

**Q: el motor reductor de 12 volt y 80 rpm, cual es el torque real?**
A: The torque of 12V 80rpm is about 15kg.cm. Torque means that when the radius of the contact area between the motor shaft and the load is 1cm, the maximum weight that the motor can load is 15kg. When the radius of the contact area is 2cm, the maximum weight that the motor can load is 7.5kg. And so on.
