DS3225 25kg Metal Gear Digital Servo Motor

Overview

The DS3225 25kg Metal Gear Digital Servo Motor is a high-torque, rugged servo engineered for demanding RC and robotics applications. Combining metal gears, a digital control system, and heat-resistant construction, the DS3225 delivers reliable performance for steering systems, robotic arms, crawlers, and large scale models that require precise positioning and sustained torque.

Key Features

• High torque output: Up to 25kg·cm at 6.8V (22kg·cm at 6.0V) for heavy-duty loads.
• Metal gear construction: Steel gears for improved durability and long service life under load.
• Digital control system: Precise angle positioning, faster response and stable holding performance.
• Wide operating voltage: 4.8V to 7.4V compatibility for use with standard and high-voltage setups.
• Dual ball bearings: Smooth rotation, lower friction and improved efficiency.
• Standard servo size: Fits most RC cars, boats, planes, drones and robotics kits.
• PWM control compatible: Easy interface with Arduino, Raspberry Pi and other microcontrollers.
• Heat resistant design: Built to withstand long operational hours without overheating.

Technical Specifications

• Torque: 22kg·cm @ 6.0V / 25kg·cm @ 6.8V
• Operating Voltage: 4.8V – 7.4V
• Rotation: 180° (±10°)
• Dimensions: Standard 40 × 20 × 40.5 mm (approx.)

Compatibility and Common Applications

The DS3225 is ideal for projects where high torque and precise control are required. Typical uses include:

• RC cars, trucks and crawlers where strong steering torque is needed
• RC boats and planes requiring reliable control surfaces
• Robotic arms, grippers and pan/tilt mechanisms in automation projects
• Custom hobby builds and automation systems that use PWM control

Installation and Control Tips

• Control interface: Standard PWM signals (compatible with most receivers and microcontrollers).
• Powering: Use an appropriate BEC or regulator when running at higher voltages (6.0V to 7.4V) to ensure stable current delivery.
• Cooling and endurance: Although heat resistant, provide ventilation for continuous heavy-load operation to maximize lifespan.
• Mounting: Standard servo mounting holes allow drop-in replacement in many RC and robotics frames.
