What is the purpose of servo motors in FANUC systems?

Servo motors play a crucial role in FANUC systems by controlling precise movement of components. They are designed to provide high accuracy and responsiveness in positional control. This capability is essential in applications such as machining, robotics, and automation, where exact positioning and velocity control are critical for operational efficiency and product quality.

The precision offered by servo motors allows machines to execute complex tasks with minimal deviation from desired paths or angles. This is achieved through closed-loop control systems, where feedback from the motor's position is continuously monitored and adjusted, ensuring that the motion corresponds exactly to the programmed commands.

In contrast, while auxiliary equipment may benefit from power provided by motors, its primary function is not their intended purpose. Reducing machine noise is not typically associated with servo motors, as their design features aim more for performance efficacy than noise reduction. Similarly, increased tool durability relates more to the choice of materials used in the tools themselves, rather than the role of servo motors. Hence, the primary objective of servo motors in FANUC systems is their ability to facilitate precise movement.
