The 9g servo motor

Hobby servo motors usually work within a voltage range of 4.8V to 6.5V, with 5V being the standard choice in most cases. While higher voltage can provide increased torque output, the commonly preferred voltage for many applications is 5V.

Typically, hobby servo motors have a limited range of motion, usually spanning from 0° to 180° due to their gear configuration. If your project necessitates a full 360° rotation, you can either select a specialized 0° to 360° motor or modify the existing motor to enable continuous rotation.

It’s important to take into account that the gears inside these motors are susceptible to wear and tear over time. If your application demands sturdier and longer-lasting motors, you have the option to choose servo motors equipped with metal gears instead of plastic ones. This upgrade significantly enhances the motor’s durability and overall lifespan, making it more suitable for demanding tasks.

Here are the specifications for your reference:

• Operating Voltage: Typically +5V
• Torque: 2.5kg/cm
• Operating Speed: 0.1s/60°
• Gear Type: Plastic
• Rotation Range: 0° to 180°
• Motor Weight: 9 grams
• Package Includes: Gear horns and screws

More about the 9g servo motor

1. Size and Weight: As the name suggests, the 9g servo motor typically weighs around 9 grams. Its compact size and lightweight nature make it suitable for applications where space and weight considerations are important.
2. Operating Voltage: These servo motors are designed to operate within a voltage range of approximately 4.8V to 6V, with 5V being the standard voltage used in most applications. This voltage range ensures the motor’s proper functioning and reliable performance.
3. Torque: The torque of a the motor is typically around 1 to 2.5 kg/cm (kilogram per centimeter). Torque is a measure of the motor’s rotational force, and this specification indicates its ability to move or hold objects, making it suitable for small to medium-sized tasks.
4. Speed: The operating speed is usually around 0.1 seconds per 60 degrees of rotation. This speed specification indicates how quickly the motor can move from one position to another.
5. Range of Motion: These motors typically have a limited range of motion, typically from 0 degrees to 180 degrees. This range makes them suitable for applications that require precise angular positioning within this span.
6. Gear Type: Many 9g servo motors come with plastic gears. While plastic gears are lightweight and cost-effective, they may not be as durable as metal gears. For more demanding applications, you can find servo motors with metal gears, which offer increased durability and resistance to wear and tear.
7. Applications: 9g servo motors are commonly used in various hobbyist projects, including radio-controlled cars, airplanes, drones, robotic arms, model trains, and other small-scale applications that require precise control of movement. Their small size and lightweight design make them ideal for these types of projects.
8. Package Contents: When you purchase a 9g servo motor, it often comes with additional components such as gear horns and screws, which are essential for attaching the motor to your project.
9. Ease of Integration: 9g servo motors are relatively straightforward to integrate into projects. They typically come with three wires for power, ground, and control signal, simplifying their connection to microcontrollers or other control systems.
10. Modifications: Some hobbyists modify these motors to enable continuous rotation, effectively turning them into small gearmotors for continuous motion applications. This modification broadens their utility enabling some to use them as makeshift stepper motors or motors.
