Smoothness and lack of ripple are crucial for the printing of elaborate color pictures on reusable plastic-type material cups offered by 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 a single pass (unlike regular color separation where each color is definitely imprinted separately). The gearheads must operate smoothly enough to synchronize ink blankets, printing plates, and glass rollers without presenting any ripple or inaccuracies that may smudge the image. In this instance, the hybrid gearhead reduces motor shaft runout mistake, which reduces roughness.
Sometimes a motor’s capability could be limited to the stage where it needs gearing. As servo manufacturers develop better motors that can muscle tissue applications through more complicated moves and create higher torques and speeds, these motors need gearheads add up to the task.

Interestingly, only about a third of the movement control systems in service use gearing at all. There are, of training course, reasons to do so. Utilizing a gearhead with a servo electric motor or using an integrated gearmotor can enable the use of a smaller motor, therefore reducing the system size and cost. There are three principal advantages of going with gears, each which can enable the use of smaller motors and drives and for that reason lower total system price:

Torque multiplication. The gears and quantity of teeth on each gear make a ratio. If a electric motor can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is mounted on its result, the resulting torque will be close to 500 in-lbs.
Whenever a motor is running 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 efficiency 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 swiftness makes turning the grinding wheel hard because the motor will cog. The variable resistance of the stone 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 motor and gear head provides smooth rotation while the gearhead output provides a more constant drive using 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 are trying to control. The use of a gearhead to better match the inertia of the engine to the inertia of the load can enable the use of a smaller engine and results in a more responsive system that’s easier to tune.
