Smoothness and absence of ripple are essential for the printing of elaborate color images on reusable plastic-type material cups servo motor gearbox offered by fast-food chains. The colour image comprises of millions of tiny ink spots of many colours and shades. The complete cup is printed in a single complete (unlike regular color separation where each color is certainly published separately). The gearheads must operate easily enough to synchronize ink blankets, printing plates, and cup rollers without presenting any ripple or inaccuracies that may smudge the image. In this case, the hybrid gearhead decreases motor shaft runout mistake, which reduces roughness.
At times a motor’s capability could be limited to the main point where it requires gearing. As servo manufacturers develop better motors that can muscle applications through more difficult moves and create higher torques and speeds, these motors require gearheads equal to the task.
Interestingly, only about a third of the movement control systems in service use gearing at all. There are, of training course, good reasons to do so. Using a gearhead with a servo motor or using a built-in gearmotor can 
enable the utilization of a smaller motor, thereby reducing the machine size and cost. There are three major advantages of choosing gears, each which can enable the use of smaller motors and drives and therefore lower total system price:
Torque multiplication. The gears and number of tooth on each gear generate a ratio. If a motor can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is attached to its output, the resulting torque will be close to 500 in-lbs.
Whenever a motor is working at 1,000 rpm and a 5:1 ratio gearhead is mounted on it, the quickness at the output will be 200 rpm. This speed decrease can improve system overall performance because many motors usually do not operate effectively at very low rpm. For example, look at a stone-grinding mechanism that will require the motor to perform at 15 rpm. This slow quickness makes turning the grinding wheel tough because the motor will cog. The variable resistance of the rock being floor also hinders its ease of turning. With the addition of a 100:1 gearhead and letting the electric motor run at 1,500 rpm, the motor and gear mind provides smooth rotation as the gearhead output provides a more constant force using its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque in accordance with 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 are trying 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 outcomes in a far more responsive system that’s easier to tune.
