Smoothness and absence of ripple are essential for the printing of elaborate color images on reusable plastic cups offered by fast-food chains. The colour image comprises of an incredible number of tiny ink dots of many colours and shades. The complete glass is printed in one complete (unlike regular color separation where each 
color is definitely published separately). The gearheads must work smoothly enough to synchronize ink blankets, printing plates, and glass rollers without introducing any ripple or inaccuracies that may smudge the picture. In this instance, the hybrid gearhead reduces motor shaft runout mistake, which reduces roughness.
Sometimes a motor’s capability may be limited to the main point where it needs gearing. As servo manufacturers develop more powerful motors that can muscles applications through more complicated moves and create higher torques and speeds, these motors need gearheads equal to the task.
Interestingly, only about a third of the movement control systems in service use gearing at all. There are, of program, good reasons to do so. Utilizing a gearhead with a servo electric motor or using a built-in gearmotor can enable the use of a smaller motor, therefore reducing the machine size and cost. There are three major advantages of going with gears, each of which can enable the use of smaller motors and drives and for that reason lower total system price:
Torque multiplication. The gears and quantity of tooth on each gear create a ratio. If a electric motor can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is attached to its output, the resulting torque will become near to 500 in-lbs.
Whenever a motor is running at 1,000 rpm and a 5:1 ratio gearhead is attached to it, the speed at the output will be 200 rpm. This speed reduction can improve system performance because many motors usually do not operate efficiently at very low rpm. For example, consider a stone-grinding mechanism that will require the motor to perform at 15 rpm. This slow velocity makes turning the grinding wheel difficult because the motor tends to cog. The variable level of resistance of the stone being ground also hinders its simple turning. With the addition of a 100:1 gearhead and letting the motor run at 1,500 rpm, the electric motor and gear head provides smooth rotation while the gearhead output provides a more constant pressure with its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque relative to frame size thanks to lightweight components, dense copper windings, and high-energy magnets. The effect is higher inertial mismatches between servo motors and the loads they want to control. The usage of a gearhead to better match the inertia of the electric motor to the inertia of the load can enable the use of a smaller motor and results in a more responsive system that is easier to tune.
