BRINGSMART 12V 160rpm DC Worm Gear Motor 10kg.cm Self-Locking Engine Reversed Mini Turbine Geared Motor for DIY Robot Rotating Table Door Lock Curtain Machine (12V 160rpm)

Great buy

I've purchased a few of these gear motors and will continue to do so, they are decent. I bought 3 of the motor speed controllers also, and one arrived dead and the other 2 went up in smoke after just a few minutes of use. I didn't do a post mortem on the dead controllers, but it seems from the extreme heat that the 7805 regulator is what burned up, or maybe the control chip itself shorted and then the regulator went next. With the damaged controllers, the motor still runs and can reverse, but only at full speed. The biggest thing I don't like about these controllers is that the control chip itself is not a standard, servicable part. The little 8-dip IC is actually an 8-bit microcontroller with custom programming, so if (when) it dies, you can't just swap in another. Competitors' products use an op-amp or 555 instead, which are easily replaced parts. Maybe there is some benefit to this custom chip, but it seems like overkill and it makes the thing end-user non-repairable. Sure, $13 is not a lot of money to replace the whole board, but a $0.70 IC is still a lot cheaper.

I used this motor to automate the chute in my snowblower. It works very well

Good product does the job
