Whenever 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 is usually unevenly distributed over the planetary gears and the drive teach operates less efficiently. Also, gear life can be shortened. These alignment adjustments require skills that aren’t normally available in the field.
Achieving a larger speed reduction ratio requires a smaller sun gear diameter (or an exceedingly large ring gear). This smaller sun gear is usually integral with its shaft, which must be smaller aswell, thereby reducing its power and its own torque or load capacity.

Various kinds gear trains, including those with planetary gears, are commonly used to obtain this the best reduction ratio. Planetary gear trains provide high stiffness and low backlash (needed for accurate procedure), plus even load distribution (to obtain optimum torque). Some planetary variations combine external-tooth pinion-and-gear models with planetary gear sections to simplify installation and boost speed. These hybrid gearheads are described later.
A basic planetary gearhead has several limitations regarding ease of installation, load capacity, and speed, all of which are related to the sun gear.

As a rule, 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 servo reducer 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 need a servo drive – this uses the opinions data to precisely control the position of the motors path and rotation distance.
Cone Drive’s stainless precision movement gearboxes are made for sterile manufacturing conditions. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, perfect for meals processing and pharmaceutical applications. The product is designed and rated to IP69k offering maximum security against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the engine size by using a gearbox to lessen speed and boost torque. Speed decrease allows rapid acceleration and deceleration of huge loads utilizing a small, less expensive motor.
