DS3240 40kg Metal Gear Digital Servo Motor

DS3240 40kg Metal Gear Digital Servo Motor – Professional High-Torque Servo

The DS3240 40kg Metal Gear Digital Servo Motor is a professional-grade, ultra-high torque servo engineered for robotics, industrial automation, and large-scale RC applications. Delivering up to 40kg·cm at 7.4V with full metal gears and digital control circuitry, this servo combines raw power with precise angle positioning for demanding projects.

Key Features and Benefits

• Massive Torque Output: Up to 40kg·cm at 7.4V (35kg·cm at 6.0V) for heavy loads and high-force tasks.
• All-Metal Gear Train: Hardened metal gears resist wear under stress for extended service life.
• Digital Control Technology: Fast response, low deadband, and accurate position holding for repeatable motion control.
• Wide Operating Voltage: 4.8V to 8.4V compatibility lets you use standard RC battery packs or regulated power supplies.
• Dual Ball Bearings: Reduces friction for smoother rotation and improved longevity under continuous use.
• Heat and Overload Resistant: Designed to maintain performance in prolonged or high-load conditions.
• Standard Size Compatibility: Fits common servo mounts for robotics, RC crawlers, boats, and automation systems.

Applications

Ideal uses include:

• Robotic arms and grippers needing high torque and precise positioning
• RC crawlers, trucks, and boats requiring durable steering or winch servos
• Industrial automation where reliable, repeatable motion under load is required
• Prototyping and AI-driven mechanical systems that demand long-life actuation

Power and Wiring Recommendations

• Use a stable power supply rated for the servo’s current draw, especially under stall conditions. For bursts of high torque, a 7.4V LiPo (2S) setup provides peak performance.
• Decouple the power rails with capacitors and ensure common ground between controller and servo.
• Use appropriate gauge wiring for longer runs to avoid voltage drop.

Mounting and Integration Tips

• Check servo dimensions and mounting hole pattern before installation to ensure compatibility.
• Limit end stops in your controller if using near-stall positions to reduce heat buildup and extend gear life.
• For continuous heavy-duty use, allow for ventilation or intermittent duty cycles to manage temperature.
