When a conventional planetary gearhead is mounted to a motor, the sun gear must be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load can be unevenly distributed over the planetary gears and the drive train operates less smoothly. Also, gear life can be shortened. These alignment modifications require skills that are not normally available 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 gear is usually integral using its shaft, which must be smaller as well, thereby reducing its power and its own torque or load capacity.
Various kinds gear trains, including those with planetary gears, are commonly used to acquire this optimum reduction ratio. Planetary gear trains offer high stiffness and low backlash (necessary for accurate procedure), plus also load distribution (to acquire maximum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify set up and boost acceleration. These hybrid gearheads are described later.
A simple planetary gearhead has a few limitations regarding simple installation, load capacity, and speed, which are related to sunlight gear.
Generally, the designer usually obtains the optimum speed decrease ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia complementing minimizes power loss in the motor, which makes it run more efficiently.
Servo motors deliver precise control of position, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors require a servo drive – this uses the opinions data to exactly control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are designed for sterile manufacturing environments. The product’s smooth surface and curved contour allows for easy cleaning and bacteria-free surfaces, perfect for food processing and pharmaceutical applications. The product is designed and ranked to IP69k offering maximum protection against contaminant ingress along with leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the electric motor size by using a gearbox to lessen speed and enhance torque. Speed reduction allows rapid acceleration and 
deceleration of large loads using a small, less costly motor.
