The SG90_9G Servo Motor is a type of small, high-torque, direct-drive motor commonly used in robotics and hobbyist projects. The SG90 is a micro servo motor, meaning that it is compact in size and ideal for applications where space is limited.

The servo motor is rated for 1.5 Kg.cm of torque, which means that it can generate a maximum force of 1.5 kilograms at a distance of 1 centimeter from the motor's axis of rotation. This makes the SG90 well-suited for a variety of applications, including controlling robotic arms, pan/tilt mechanisms, and other moving parts in small robots and hobby projects.

The SG90 is controlled by a pulse-width modulation (PWM) signal, which allows the user to accurately position the motor's shaft. The motor can rotate to any position within its range of motion, and can be set to hold that position even after the control signal is removed.

In summary, the SG90_9G Servo Motor is a versatile, compact, and high-torque motor that is well-suited for a wide range of applications in robotics and hobby projects.

The 9g is a tiny and lightweight servo motor with a high power output (1.5Kg.Cm) and is a great all-round servo motor.. A set of plastic motor horn are included to allow you to quickly fasten something to the servo motor without hassle.
