Smoothness and lack of ripple are crucial for the printing of elaborate color pictures on reusable plastic-type cups available at 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 pass (unlike regular color separation where each color is usually published separately). The gearheads must run smoothly enough to synchronize ink blankets, printing plates, and cup rollers without presenting any ripple or inaccuracies that may smudge the picture. In this instance, the hybrid gearhead decreases motor shaft runout error, which reduces roughness.
At times a motor’s capability could be limited to the main point where it requires gearing. As servo producers develop better motors that can muscle tissue applications through more difficult moves and generate higher torques and speeds, these motors need 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 training course, good reasons to do therefore. Using a gearhead with a servo servo motor gearbox electric motor or using an integrated gearmotor can enable the use of a smaller motor, thereby reducing the system size and cost. There are three major advantages of going with gears, each which can enable the utilization of smaller sized motors and drives and for that reason lower total system price:

Torque multiplication. The gears and amount of teeth on each gear generate a ratio. If a engine can generate 100 in-pounds of torque, and a 5:1 ratio equipment head is mounted on its output, 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 mounted on it, the rate at the output will be 200 rpm. This speed reduction can improve system performance because many motors do not operate efficiently at very 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 will cog. The variable resistance of the stone being ground 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 electric motor and gear head provides smooth rotation while the gearhead output provides a more constant push with its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque relative to frame size thanks to lightweight components, dense copper windings, and high-energy magnets. The result 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 strain can enable the use of a smaller electric motor and results in a far more responsive system that is easier to tune.
