Summary:...
Geared motors are usually used in positioning control applications. A major example is package or material handling, in which the load needs to be picked up or placed on a designated location. There are those application scenarios that require high-precision manufacturing and distribution.
The application requirements dictate the accuracy level that the geared motor needs to achieve. For example, a low-precision application is a kind of "good enough", for example, a robotic arm places a box on a plate. On the other hand, high-precision positioning may require accuracy to the order of thousands of inches or even micrometers.
In fact, any type of geared motor can be used for positioning control. The real question is how precise the positioning needs to be. In this case, the focus has shifted to the type of geared motor.
And why is gearing so important? The main reason for the inaccurate positioning of the geared motor is the backlash of the gear. Therefore, in the application, if accuracy is a very important variable, then you must ensure that the backlash of the geared motor you choose must be very small. Manufacturers have a variety of methods to reduce gear backlash, including preloading and using gears that reduce or eliminate backlash from the beginning.
