Smoothness and lack of ripple are essential for the printing of elaborate color images on reusable plastic-type material cups offered by fast-food chains. The color image is made up of millions of tiny ink spots of many shades and shades. The complete glass is printed in a single complete (unlike regular color separation where each color can be published separately). The gearheads must operate efficiently enough to synchronize ink blankets, printing plates, and glass rollers without presenting any ripple or inaccuracies that may smudge the picture. In cases like this, the hybrid gearhead decreases motor shaft runout error, which reduces roughness.
Sometimes a motor’s capability may be limited to the point where it needs gearing. As servo producers develop more powerful motors that can muscles applications through more difficult moves and generate higher torques and speeds, these motors require gearheads add up to the task.

Interestingly, no more than a third of the motion control systems operating use gearing at all. There are, of program, good reasons to do therefore. Utilizing a gearhead with a servo electric motor or using a gearmotor can enable the use of a smaller motor, thereby reducing the machine size and price. There are three principal advantages of going with gears, each of which can enable the use of smaller sized motors and drives and therefore lower total system cost:

Torque multiplication. The gears and number of tooth 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 output, the resulting torque will end up being 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 functionality because many motors usually 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 rate makes servo motor gearbox turning the grinding wheel difficult because the motor will cog. The variable resistance of the rock being surface also hinders its simple turning. With the addition of a 100:1 gearhead and letting the motor run at 1,500 rpm, the engine and gear head provides smooth rotation as the gearhead output offers a more constant power using its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque in accordance with frame size because of lightweight components, dense copper windings, and high-energy magnets. The result is better inertial mismatches between servo motors and the loads they want to control. The utilization 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 electric motor and results in a far more responsive system that is easier to tune.
