Selection Basics
Why Motor Power Alone Is Not Enough to Select a Planetary Gearbox?
Motors with the same power may have different speeds, Inertia & Peak Capability, Select the gearbox based on output torque, Gear Ratio, Determine inertia and interface requirements together.

Gear Ratio
5:1 and 10:1 What Is the Practical Selection Difference?
Increasing the gear ratio reduces output speed, Theoretical output torque increases, It also changes reflected inertia and dynamic response.

Parameters
Rated Torque or Peak Torque?
Use rated torque for continuous operation, Starting, Check peak torque and its allowable duration for braking and brief shock loads.

Dynamic Operating Conditions
How Frequent Starts and Stops Affect Gearbox Life?
Frequent acceleration and deceleration create repeated peak loads, Increase gear loading, Thermal and mechanical loads on bearings and lubrication systems.

Accuracy
Why Low Backlash Does Not Guarantee High Positioning Accuracy?
Positioning accuracy also depends on structural rigidity, Coupling, Encoder, Lead screws and control settings also affect accuracy.

Installation
Which Motor Interface Dimensions Must Be Checked?
Pay particular attention to shaft diameter, Shaft Length/Keyway, Pilot Diameter & Hole Spacing, Confirm flange thickness and thread specifications when necessary.

Troubleshooting
Does High Gearbox Temperature Always Indicate a Quality Problem?
Check the load factor first, Lubrication, Concentricity & Acceleration/Deceleration Time, Then investigate possible internal faults.
