BASICS OF SERVO MOTOR CONTROL
Ever wondered how metal cutting & forming machines provide such accurate motion for milling, lathes, etc.? Or how a robotic vehicle in military application controls bomb detonation with careful precision? Or how do spinning machines in textile factories operate with unfailing accuracy and consistency for repetitive tasks? It’s all thanks to the precise control of servo systems. Let’s start with a fundamental question: What is a servo? Technically, the term ‘servo’ refers to a function and not a specific device, although the term is used as a short form for a servo motor or servo system. DIFFERENCE BETWEEN SERVO MOTORS AND DRIVES? To many, a servo drive and a servo motor can seem like the same thing because they are often used together in tandem. In reality, they play different roles in automation. What is a servo motor ? Servo motors are electrical devices made up of various parts, that move and rotate parts of a machine with efficiency and precision. Servo motor functions ...
