Smoothness and lack of ripple are essential for the printing of elaborate color images on reusable plastic cups available at fast-food chains. The colour image comprises of an incredible number of tiny ink dots of many colours and shades. The complete glass is printed in one pass (unlike regular color separation where each color is certainly imprinted separately). The gearheads must function efficiently enough to synchronize ink blankets, printing plates, and cup rollers without presenting any ripple or inaccuracies that may smudge the picture. In this case, the hybrid gearhead decreases motor shaft runout mistake, which reduces roughness.
At times a motor’s capability may be limited to the main point where it requires gearing. As servo producers develop better motors that can muscle applications through more complicated moves and create higher torques and speeds, these motors require gearheads equal to the task.

Interestingly, no more than a third of the motion control systems operating use gearing at all. There are, of course, good reasons to do so. Using a gearhead with a servo engine or using a built-in gearmotor can enable the use of a smaller motor, therefore 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 for that reason lower total system cost:

Torque servo motor gearbox multiplication. The gears and amount of the teeth on each gear generate a ratio. If a engine can generate 100 in-pounds of torque, and a 5:1 ratio gear head is mounted on its output, the resulting torque will become close to 500 in-lbs.
When a motor is operating at 1,000 rpm and a 5:1 ratio gearhead is attached to it, the velocity at the output will be 200 rpm. This speed reduction can improve system efficiency because many motors do not operate efficiently at suprisingly low rpm. For example, consider a stone-grinding mechanism that requires the motor to run at 15 rpm. This slow swiftness makes turning the grinding wheel hard because the motor will cog. The variable level of resistance of the stone being ground also hinders its simple turning. By adding a 100:1 gearhead and letting the motor run at 1,500 rpm, the engine and gear mind provides smooth rotation while the gearhead output provides a more constant force with its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque in accordance with frame size because of 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 better match the inertia of the electric motor to the inertia of the load can enable the utilization of a smaller motor and outcomes in a far more responsive system that is easier to tune.
