In the ever-evolving world of robotics and automation, precise control over movement is crucial. Whether you're designing a robotic arm, a small drone, or building a home automation system, the choice of motor can significantly affect the overall performance of your project. Among the various options available, the SG90 Servo Motor 360 stands out as a popular, reliable, and cost-effective solution for both hobbyists and professionals.
What is an SG90 Servo Motor 360?
The SG90 Servo Motor 360 is a small yet powerful motor known for its versatility and ease of use. It belongs to the category of servo motors, which are designed to rotate to a specific angle and hold that position until instructed to move again. Unlike traditional DC motors, servo motors offer precise control over both speed and angle. The "360" in its name refers to the fact that this servo motor can rotate continuously in either direction, making it distinct from standard servos that typically have a range of 0 to 180 degrees.
The SG90 Servo Motor 360 is built with a small footprint, typically measuring around 22.5mm x 11.5mm x 22mm and weighing only about 9 grams. Despite its size, it delivers high torque, making it ideal for small-scale robotics and automation projects. It operates on a voltage range of 4.8V to 6V, and its 360-degree rotation allows it to be used in continuous motion applications, unlike other servos that have limited movement.

Common Applications of SG90 Servo Motor 360
The SG90 Servo Motor 360 is widely used in robotics. Its precise control and ability to perform continuous rotations make it a popular choice for driving wheels, robotic arms, and other moving parts. For example, in robot chassis designs, it can serve as a key component for driving the wheels or even a rotating turret. Its small size makes it perfect for building compact robots for educational purposes or hobby projects.
Many enthusiasts and DIYers choose the SG90 Servo Motor 360 for building everything from small robotic vehicles to interactive art installations. Its ability to be easily controlled via an Arduino or similar microcontroller makes it accessible to beginners, yet it also offers the precision and control that more advanced users require. Whether you're constructing a servo-powered camera pan-and-tilt system or a rotating display stand, the SG90 motor provides a reliable and cost-effective solution.
In the world of drone and RC vehicle enthusiasts, the SG90 Servo Motor 360 is often used for controlling the steering mechanisms of cars or for adjusting the angle of the camera on drones. Its continuous rotation feature is ideal for applications where steering or movement needs to be constantly controlled.
The SG90 Servo Motor 360 is also a favorite among educators and students. Its simplicity and affordability make it an excellent choice for teaching students about robotics and automation. By using this servo motor, students can easily learn about motor control, circuits, and mechanical design, offering hands-on experience with real-world technology.
How Does the SG90 Servo Motor 360 Work?
Understanding the working principle of a servo motor is essential for effectively utilizing it in your projects. A servo motor consists of three main components: the motor itself, a feedback system (usually a potentiometer), and a control circuit.
The control circuit receives a PWM signal from a microcontroller (like an Arduino) that determines the desired position of the motor. For standard servos, this signal defines the position between 0 and 180 degrees. However, for the SG90 Servo Motor 360, the motor is designed for continuous rotation, so the PWM signal controls the speed and direction of rotation instead of a fixed position.
The feedback mechanism ensures that the servo motor maintains its desired position or speed. In the case of continuous rotation, this feedback allows the motor to adjust its speed and direction in response to the PWM signals sent from the controller, resulting in smooth, controlled motion.
Controlling the SG90 Servo Motor 360 with Arduino
One of the easiest ways to control the SG90 Servo Motor 360 is by using an Arduino board. Arduino is an open-source electronics platform that makes it simple to interface with sensors, motors, and other hardware components. Here’s a step-by-step guide to controlling the SG90 motor with an Arduino:
Arduino board (e.g., Arduino Uno)
Wiring the SG90 Servo Motor 360:
Connect the Servo to the Arduino:
The servo has three wires: red (VCC), brown (GND), and yellow (PWM signal).
Connect the red wire to the 5V pin on the Arduino.
Connect the brown wire to one of the GND pins on the Arduino.
Connect the yellow wire to a PWM-capable pin (e.g., pin 9) on the Arduino.
Open the Arduino IDE, write the following simple code to rotate the SG90 Servo Motor 360:
myServo.attach(9); // Attach the servo to pin 9
myServo.write(0); // Rotate the motor to one direction
myServo.write(180); // Rotate the motor to the other direction
After uploading the code, the servo should rotate back and forth. You can adjust the speed by modifying the delay times and experiment with different PWM signals to control the motor's direction.
Motor Not Moving: Check if the wiring is correct and the power supply is sufficient. If using a battery, make sure it's fully charged.
Motor Jittering or Sticking: This could be due to insufficient power or interference from other components. Use a separate power supply for the motor if needed.
Slow Response or Inconsistent Motion: Ensure that the PWM signals are properly calibrated and that the Arduino code is running correctly.
