SG90 PDF Datasheet – Micro Servo Motor – Tower pro

A servo motor is a type of rotary actuator that is widely used in various applications to control the position, speed, and angular displacement of mechanical systems. It’s an essential component in robotics, automation, aerospace, manufacturing, and many other industries. Servo motors are known for their ability to provide precise control and feedback, making them valuable in applications that require accurate positioning and motion control.

SG90 pdf motor


SG90 is 9 g Micro Servo Tiny and lightweight with high output power. Servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds but smaller. You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. It comes with a 3 horns (arms) and hardware.


Key characteristics and features:

1. Control System: Servo motors are typically controlled using closed-loop control systems. This means that they have feedback mechanisms (such as encoders or potentiometers) that provide information about the motor’s actual position, speed, or torque. The control system adjusts the motor’s operation based on this feedback to achieve the desired performance.

2. Position and Speed Control: Servo motors are designed to control the position and speed of the output shaft. By sending specific control signals, usually in the form of PWM (Pulse Width Modulation) signals, the motor’s shaft can be rotated to a precise angle and speed.

3. High Precision: Servo motors are known for their high precision and accuracy. They can achieve very fine increments of movement and maintain the desired position with minimal error.

4. Torque Output: Servo motors can provide varying levels of torque output, depending on their size and design. This torque output allows them to move mechanical loads and overcome resistance.
