How-To: Calculating Servo Motor Inertia Ratio for High-Speed Indexing
When an industrial automation engineer sizes a servo motor for a high-speed indexing application, simply matching the torque and speed requirements is a recipe for disaster. If the inertia of the driven load vastly exceeds the inertia of the motor rotor, the servo system will struggle to control the load dynamically. This mismatch results in […]
