How Backlash Affects Robot and CNC Positioning Accuracy

SELECTION GUIDE Backlash creates a dead zone when torque reverses, but load-side positioning error also includes elastic twist, structural deflection and control behavior. Quick answer How Backlash Affects Robot and CNC Positioning Accuracy should be evaluated from...

Choosing Gear Ratio for a Servo Motor and Planetary Gearbox

SELECTION GUIDE Gear ratio links motor speed, output speed, torque multiplication and reflected inertia, so it should be chosen as a system variable rather than a single catalogue number. Quick answer Choosing Gear Ratio for a Servo Motor and Planetary Gearbox should...

How to Size a Precision Planetary Gearbox for a Servo Axis

SELECTION GUIDE Start from the load motion profile, then work backward through output torque, speed, ratio, duty and motor matching. Quick answer How to Size a Precision Planetary Gearbox for a Servo Axis should be evaluated from the real load and motion conditions,...
