Smoothness and absence of ripple are crucial for the printing of elaborate color images on reusable plastic cups available at fast-food chains. The color image comprises of an incredible number of tiny ink dots of many colors and shades. The entire glass is printed in a single pass (unlike regular color separation where each color is usually published separately). The gearheads must operate efficiently enough to synchronize ink blankets, printing plates, and glass rollers without introducing any ripple or inaccuracies that may smudge the picture. In cases like this, the hybrid gearhead decreases motor shaft runout mistake, which reduces roughness.
Sometimes a motor’s capability could be limited to the main point where it needs gearing. As servo manufacturers develop better motors that can muscles applications through more complicated moves and generate higher torques and speeds, these motors need gearheads add up to the task.
Interestingly, no more than a third of the movement control systems in service use gearing at all. There are, of program, reasons to do therefore. Utilizing a gearhead with a servo motor or using an integrated gearmotor can servo gear reducer enable the utilization of a smaller motor, therefore reducing the system size and price. There are three primary advantages of choosing gears, each which can enable the use of smaller sized motors and drives and for that reason lower total system cost:
Torque multiplication. The gears and quantity of the teeth on each gear produce a ratio. If a engine can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is mounted on its result, the resulting torque will become near 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 decrease can improve system functionality because many motors usually 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 acceleration makes turning the grinding wheel tough because the motor tends to 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 engine run at 1,500 rpm, the electric motor and gear head provides smooth rotation as the gearhead output offers a more constant drive using its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque relative to frame size because of lightweight components, dense copper windings, and high-energy magnets. The effect is higher inertial mismatches between servo motors and the loads they want to control. The utilization of a gearhead to better match the inertia of the motor to the inertia 
of the strain can enable the utilization of a smaller electric motor and outcomes in a far more responsive system that’s easier to tune.
