Smoothness and absence of ripple are essential for the printing of elaborate color images on reusable plastic material cups offered by fast-food chains. The color image is made up of an incredible number of tiny ink spots of many colours and shades. The complete glass is printed in one move (unlike regular color separation where each color is usually published separately). The gearheads must operate efficiently 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 reduces motor shaft runout mistake, which reduces roughness.
At times a motor’s capability could be limited to the main point where it needs gearing. As servo producers develop more powerful motors that can muscle mass applications through more difficult moves and generate higher torques and speeds, these motors need gearheads equal to the task.
Interestingly, only about a third of the movement control systems operating use gearing at 
all. There are, of program, good reasons to do therefore. Using a gearhead with a servo motor or using a built-in gearmotor can enable the utilization of a smaller motor, therefore reducing the system size and price. There are three primary advantages of choosing gears, each which can enable the use of smaller motors and drives and for that reason lower total system cost:
Torque multiplication. The gears and amount of teeth on each gear make a ratio. If a engine can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is mounted on its output, the resulting torque will end up being near to 500 in-lbs.
When a motor is running at 1,000 rpm and a 5:1 ratio gearhead is mounted on it, the quickness at the servo gear reducer output will be 200 rpm. This speed decrease can improve system efficiency because many motors do not operate efficiently at suprisingly low rpm. For example, consider a stone-grinding mechanism that will require the motor to run at 15 rpm. This slow acceleration makes turning the grinding wheel tough because the motor tends to cog. The variable level of resistance of the rock being surface also hinders its ease of turning. By adding a 100:1 gearhead and letting the engine run at 1,500 rpm, the motor and gear head provides smooth rotation as the gearhead output provides a more constant power 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 use of a gearhead to raised match the inertia of the motor to the inertia of the load can enable the use of a smaller electric motor and outcomes in a more responsive system that is easier to tune.
