Question
Answer and Explanation
Servo ratings are specifications that define a servo motor’s performance capabilities. Understanding these ratings is crucial for selecting the right servo for a specific application. Common servo ratings include torque, speed, voltage, current, and positional accuracy.
Torque is the rotational force a servo can exert, usually measured in oz-in, kg-cm, or N-m. Speed refers to how fast the servo can rotate, often given in RPM or degrees per second. Voltage specifies the operating voltage range, and current indicates the amount of electrical current the servo requires. Positional accuracy describes how precisely the servo can reach a given position. Other important ratings can include gear ratio, which affects torque and speed, and the servo’s physical size and weight.
These ratings determine the servo's suitability for different uses, from simple RC applications to complex industrial automation. Carefully reviewing and comparing servo ratings is essential to ensure optimal performance and avoid damage due to overloading or insufficient capabilities.
