Smoothness and absence of ripple are essential for the printing of elaborate color images on reusable plastic material cups available at fast-food chains. The color image is made up of an incredible number of tiny ink dots of many colors and shades. The complete cup is printed in one pass (unlike regular color separation where each color can be printed separately). The gearheads must work easily enough to synchronize ink blankets, printing plates, and glass rollers without introducing any ripple or inaccuracies that may smudge the picture. In this instance, the hybrid gearhead reduces motor shaft runout mistake, which reduces roughness.
Sometimes a motor’s capability may be limited to the stage where it requires gearing. As servo manufacturers develop better motors that can muscles applications through more complicated moves and generate higher torques and speeds, these motors require 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 course, reasons to do so. Using a gearhead with a servo electric motor or using an integrated gearmotor can enable the use of a smaller motor, thereby reducing the system size and price. There are three principal advantages of going with gears, each which can enable the use of smaller sized motors and drives and for that reason lower total system price:

Torque multiplication. The gears and amount of tooth on each gear make a ratio. If a motor can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is mounted on its output, the resulting torque will become 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 velocity at the output will be 200 rpm. This speed decrease can improve system overall performance because many motors do not operate efficiently at very low rpm. For example, look at a stone-grinding mechanism that requires the motor to perform at 15 rpm. This slow rate makes turning the grinding wheel tough because the motor will cog. The variable level of resistance of the stone being surface also hinders its simple turning. By adding a 100:1 gearhead and letting the electric motor run at 1,500 rpm, the electric motor and gear mind provides smooth rotation as the gearhead output provides a more constant force using its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque in accordance with frame size thanks to lightweight materials, dense copper windings, and high-energy magnets. The result is higher inertial mismatches between servo motors and the loads they are trying to control. The use of a gearhead to raised match the inertia of the engine to the inertia of the strain can enable the utilization of a smaller electric motor and outcomes in a more responsive system that’s easier to tune.
