Smoothness and lack of ripple are crucial for the printing of elaborate color pictures on reusable plastic-type material cups available at fast-food chains. The color image comprises of an incredible number of tiny ink spots of many colors and shades. The entire glass is printed in a single complete (unlike regular color separation where each color is definitely published separately). The gearheads must operate easily enough to synchronize ink blankets, printing plates, and cup rollers without introducing any ripple or inaccuracies that may smudge the image. In this instance, the hybrid gearhead servo gear reducer reduces motor shaft runout error, which reduces roughness.
At times a motor’s capability may be limited to the main point where it requires gearing. As servo manufacturers develop better motors that can muscle mass applications through more complicated moves and produce higher torques and speeds, these motors need gearheads equal to the task.

Interestingly, no more than a third of the movement control systems in service use gearing at all. There are, of course, good reasons to do therefore. Utilizing a gearhead with a servo motor or using a gearmotor can enable the use of a smaller motor, thereby reducing the machine size and cost. There are three primary advantages of choosing gears, each of which can enable the usage of smaller motors and drives and therefore lower total system price:

Torque multiplication. The gears and amount of teeth on each gear create a ratio. If a engine can generate 100 in-lbs of torque, and a 5:1 ratio gear head is attached to its output, the resulting torque will become close to 500 in-lbs.
Whenever a motor is working at 1,000 rpm and a 5:1 ratio gearhead is attached to it, the rate at the output will be 200 rpm. This speed reduction can improve system efficiency because many motors do not operate effectively at suprisingly low rpm. For example, look at a stone-grinding mechanism that requires the motor to run at 15 rpm. This slow swiftness makes turning the grinding wheel tough because the motor will cog. The variable resistance of the stone being ground also hinders its ease of turning. By adding a 100:1 gearhead and letting the electric motor run at 1,500 rpm, the motor and gear head provides smooth rotation as the gearhead output provides a more constant force with its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque relative to frame size thanks to lightweight materials, dense copper windings, and high-energy magnets. The effect is greater inertial mismatches between servo motors and the loads they want to control. The utilization of a gearhead to better match the inertia of the motor to the inertia of the load can enable the use of a smaller motor and results in a far more responsive system that is easier to tune.
