When a conventional planetary gearhead is mounted to a engine, the sun gear should be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load is certainly unevenly distributed over the planetary gears and the drive teach operates less easily. Also, gear life could be shortened. These alignment changes require skills that aren’t normally obtainable in the field.
Achieving a more substantial speed reduction ratio requires a smaller sun equipment diameter (or an exceedingly large ring gear). This smaller sun equipment is usually integral using its shaft, which should be smaller as well, thereby reducing its power and its torque or load capacity.
Several types of gear trains, including people that have planetary gears, are generally used to acquire this ideal reduction ratio. Planetary gear trains offer high stiffness and low backlash (needed for accurate operation), plus also load distribution (to acquire optimum torque). Some planetary variations combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify installation and boost speed. These hybrid gearheads are described later.
A basic planetary gearhead has a few limitations regarding ease of installation, load capacity, and speed, which are related to the sun gear.
As a rule, the designer 
usually obtains the the best speed reduction ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia matching minimizes power loss in the motor, which makes it run more efficiently.
Servo motors deliver precise control of placement, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors require a servo drive – this uses the feedback data to exactly control the position of the motors direction and rotation distance.
Cone Drive’s stainless steel precision movement gearboxes are made for sterile manufacturing conditions. The product’s smooth surface area and curved contour allows for easy cleaning and bacteria-free surfaces, perfect for food processing and pharmaceutical applications. The merchandise is designed and ranked to IP69k providing maximum safety against contaminant ingress along with leak free operation.
Servomotor selection usually begins with the designer wanting to reduce the engine size by utilizing a gearbox to reduce speed and boost torque. Speed decrease allows rapid acceleration and deceleration of large loads utilizing a small, less costly motor.
