Smoothness and lack of ripple are crucial for the printing of elaborate color pictures on reusable plastic cups offered by fast-food chains. The colour image comprises of millions of tiny ink spots of many colors and shades. The entire glass is printed in one move (unlike regular color separation where each color is definitely imprinted 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 reduces motor shaft runout mistake, which reduces roughness.
At times a motor’s capability may be limited to the point where it requires gearing. As servo producers develop better motors that can muscle mass applications through more complicated moves and produce 
higher torques and speeds, these motors need gearheads add up to the task.
Interestingly, no more than a third of the motion control systems in service use gearing at all. There are, of program, reasons to do therefore. Using a gearhead with a servo motor or using an integrated gearmotor can enable the usage of a smaller motor, thereby reducing the machine size and price. There are three principal advantages of choosing gears, each of which can enable the use of smaller motors and drives and servo motor gearbox therefore lower total system cost:
Torque multiplication. The gears and amount of teeth on each gear create a ratio. If a electric motor can generate 100 in-lbs of torque, and a 5:1 ratio gear head is mounted on its output, the resulting torque will become near to 500 in-lbs.
Whenever a motor is operating at 1,000 rpm and a 5:1 ratio gearhead is mounted on it, the speed at the output will be 200 rpm. This speed reduction can improve system efficiency because many motors usually do not operate efficiently at suprisingly low rpm. For example, look at a stone-grinding mechanism that will require the motor to run at 15 rpm. This slow rate makes turning the grinding wheel tough because the motor tends to cog. The variable level of 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 mind provides smooth rotation as the gearhead output provides a more constant push 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 higher inertial mismatches between servo motors and the loads they want to control. The use of a gearhead to raised match the inertia of the electric motor to the inertia of the load can enable the usage of a smaller motor and outcomes in a far more responsive system that’s easier to tune.
