When a conventional planetary gearhead is mounted to a electric 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 easily. Also, gear life can be shortened. These alignment modifications require skills that are not normally available in the field.
Achieving a larger speed reduction ratio takes a smaller sun gear diameter (or an exceptionally large ring gear). This smaller sun gear is usually integral using its shaft, which should be smaller aswell, thereby reducing its power and its torque or load capacity.

Several types of 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 (needed for accurate procedure), plus also load distribution (to obtain maximum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify set up and boost rate. These hybrid gearheads are described later.
A simple planetary gearhead has several limitations regarding simple servo reducer installation, load capacity, and speed, all of which are related to sunlight gear.

Generally, the designer usually obtains the ideal speed reduction ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia matching minimizes power loss in the motor, making 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 precisely control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are made for sterile manufacturing environments. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, ideal for meals processing and pharmaceutical applications. The product is designed and rated to IP69k offering maximum protection against contaminant ingress as well as leak free operation.
Servomotor selection usually starts with the designer wanting to reduce the engine size by utilizing a gearbox to lessen speed and increase torque. Speed reduction allows speedy acceleration and deceleration of large loads utilizing a small, less expensive motor.
