Smoothness and absence of ripple are crucial for the printing of elaborate color images on reusable plastic-type cups available at fast-food chains. The color image comprises of millions of tiny ink spots of many colours and shades. The complete glass is printed in one complete (unlike regular color separation where each color is published separately). The gearheads must work smoothly enough to synchronize ink blankets, printing plates, and cup rollers without presenting any ripple or inaccuracies that may smudge the image. In cases like this, the hybrid gearhead reduces motor shaft runout mistake, which reduces roughness.
At times a motor’s capability may be limited to the point where it needs gearing. As servo manufacturers develop more powerful motors that can muscle mass applications through more complicated moves and generate higher torques and speeds, these motors need gearheads add up to the task.
Interestingly, only about a third of the movement control systems operating use gearing at all. There are, of training course, good reasons to do therefore. 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 system size and price. There are three main advantages of going with gears, each of which can enable the use of smaller motors and drives and therefore lower total system price:
Torque multiplication. The gears and quantity of teeth on each gear generate a ratio. If a electric motor can generate 100 in-pounds of torque, and a 5:1 ratio gear head is mounted on its result, the resulting torque will become near to 500 in-lbs.
When a motor is working at 1,000 rpm and a 5:1 ratio gearhead is attached to it, the acceleration at the output will be 200 rpm. This speed reduction can improve system overall performance because many motors do not operate effectively at very low rpm. For example, look at a stone-grinding mechanism that requires the motor to perform at 15 rpm. This slow swiftness makes turning the grinding wheel challenging because the motor will cog. The variable resistance of the stone being floor also hinders its simple turning. With the addition of a 100:1 gearhead and letting the motor run at 1,500 rpm, the motor and gear mind provides smooth rotation as the gearhead output provides a more servo motor gearbox constant push using its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque relative to frame size because of lightweight materials, dense copper windings, and high-energy magnets. The result is higher inertial mismatches between servo motors and the loads they are trying 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.
