BMT Micro Servo 9G SG90 180 1.6kg Torque 3.5-6V

The BMT Micro Servo 9G SG90 is a compact and lightweight servo motor designed for robotics, remote-controlled models, Arduino projects and other small electromechanical applications. Its small size and low weight make it particularly suitable for applications where space and weight are limited.

The servo provides approximately 180 of rotational movement, allowing approximately 90 of movement in each direction from the centre position. With a stated no-load operating speed of 0.12 seconds per 60 at 4.8V, it provides responsive movement for small robotic mechanisms and model-control applications.

The servo operates from approximately 3.5-6V, making it suitable for a wide range of low-voltage electronics projects. At 6V, the supplied specifications state a stall torque of approximately 1.6kg, while approximately 1.2kg is specified at 4.8V.

180 Rotation

The BMT Micro Servo provides approximately 180 of total rotational movement, making it suitable for mechanisms that require controlled angular positioning.

The approximate movement range is:

• 90 in one direction
• Centre position
• 90 in the opposite direction

This makes the servo suitable for steering mechanisms, robotic joints, sensor positioning and other projects requiring controlled angular movement.

Torque and Speed

The servo provides a balance between compact size, movement speed and available torque.

At 4.8V, the stated no-load speed is approximately 0.12 seconds per 60 , while the stall torque is approximately 1.2kg.

At 6V, the stated stall torque increases to approximately 1.6kg.

Actual performance will depend on the supply voltage, mechanical load, operating conditions and servo installation.

Compact 9g Design

The lightweight 9g construction makes this servo particularly useful for applications where larger servos would add unnecessary weight or take up too much space.

Its approximately 23 x 12.2 x 29mm dimensions allow it to be incorporated into compact robotic mechanisms, model aircraft, boats and other small projects.

Applications

The BMT 9G Micro Servo is suitable for a wide range of applications, including:

• Arduino projects
• Robotics
• Robot arms
• Robotic joints
• RC helicopters
• RC boats
• Model vehicles
• Steering mechanisms
• Camera or sensor positioning
• Small automated mechanisms
• DIY electronics
• Educational robotics
• STEM projects
• Microcontroller-controlled mechanisms

Easy Microcontroller Integration

The JR-compatible servo interface makes the unit suitable for use with compatible servo-control outputs from microcontrollers and development boards.

It can be controlled by suitable Arduino-compatible boards and other microcontrollers capable of generating the required servo control signal.

When connecting the servo to a development board, ensure that the servo's power requirements are supported. For projects using multiple servos or applications involving higher mechanical loads, an appropriately rated external power supply may be required.

Note: Servo accessories such as mounting screws, servo horns and other hardware are not specified as included and may vary by supplied version.
