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 is usually unevenly distributed over the planetary gears and the drive train operates less easily. Also, gear life could be shortened. These alignment changes require skills that aren’t normally obtainable in the field.
Achieving a larger speed reduction ratio takes a smaller sun equipment diameter (or an exceptionally large ring equipment). This smaller sun equipment is usually integral using its shaft, which should be smaller aswell, thereby reducing its power and its torque or load capability.

Several types of gear trains, including those with planetary gears, are commonly used to obtain this the best possible reduction ratio. Planetary gear trains offer high stiffness and low backlash (necessary for accurate procedure), plus also load distribution (to obtain optimum torque). Some planetary variations combine external-tooth pinion-and-gear sets with planetary gear sections to simplify set up and boost quickness. These hybrid gearheads are described later.
A simple planetary gearhead has some limitations regarding simple 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 reduction in the motor, making it run more efficiently.

Servo motors deliver precise control of placement, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors need a servo drive – this uses the opinions data to exactly control the position of the motors direction and rotation distance.
Cone Drive’s stainless precision motion gearboxes are designed 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 ranked to IP69k providing maximum safety against contaminant ingress in addition to leak free operation.
Servomotor selection usually begins with the designer wanting to reduce the electric motor size by utilizing a gearbox to reduce speed and boost torque. Speed reduction allows rapid acceleration and deceleration of huge loads using a small, less costly motor.
