Many customers came to us, looking for gear motor solution with POLOLU motor. 

POLOLU motor is one of the famous online shops for robotics parts, including gear motors. As an online shop, their parts are much more expensive than the manufacturers. So, as far as I know, their customers are mainly amateur, and DIY something for a hobby, or some engineers, who source their samples only for prototype, and will come to us when mass production.

Different from these online shops, we don‘t sell the stock, all of our motors are custom-made especially for your application, like the voltage, the speed, and the torque. We pay attention to full details involved in your application , such as the noise , the current consumption, the work enviroment . No doubt we could offer you an ideal gearbox motor solution to match your product.

We ever tested some motors from some online shops, which the customers sent to us for our evaluation. We find that  DC motors are of too high speed. With the gearbox, usually, we don‘t advise high speed more than 9000 RPM for big DC motors, like 385 motors, 395 motors, 555 motor, 545 motor, and 755 motors.  Otherwise, too high-speed DC motors would cause broken gears, most importantly, it would make bigger noise, and shorten its lifetime. Meantime, for a micro DC motor, if its speed is too low, it would be easy to deposit carbon, and do harm to motors.

Of course, if it is for a personal hobby, there will be no problem, but if you need carry mass production, you‘d better do a full test, and optimize the motor, to make your product more competitive on the market.
