MG996R Digital Metal Gear High Torque Servo Motor (180 Degree Rotation)

Product Description The MG996R is an upgraded version of the famous MG995 servo, featuring a redesigned IC and control system for improved accuracy and holding torque. This high-torque digital servo is built with a rugged all-metal gear train and a double ball-bearing shaft, making it ideal for heavy-duty applications like robotic arms, hexapods, and 1/8 scale RC cars. Unlike analog servos, its digital controller provides a faster response and a tighter dead band, ensuring your project maintains its position even under significant mechanical stress.

Key Features

• High Torque Performance: Delivers up to 11 kg-cm at 6V, providing enough power to lift heavy robotic limbs or steer large RC vehicles.

• Metal Gear Durability: The internal geartrain is entirely made of metal, preventing the "stripped gear" issues common in plastic-gear servos under load.

• Double Ball Bearing: Equipped with dual bearings on the output shaft to reduce friction and improve the precision of the 180-degree sweep.

• Digital Control: Features an advanced digital PCB that offers superior holding power and more precise centering compared to older analog models.

• Universal Compatibility: Works seamlessly with Arduino, Raspberry Pi, and ESP32 using standard PWM libraries and 3-pin headers.

Technical Details

• Coreless Motor: High-speed coreless motor design reduces weight and improves acceleration compared to standard iron-core motors.

• Current Draw: Can pull over 1A under stall; it is highly recommended to use an external power source rather than the Arduino 5V pin.

• Pulse Width: Standard 500µs to 2500µs pulse range for a full 180-degree movement.

• Operating Temperature: Rated for stable operation between 0°C and 55°C, suitable for most indoor and outdoor hobbyist environments.

• Spline Count: Features a standard 25-tooth (25T) output spline, compatible with a wide variety of aluminum and plastic servo horns.

• Connector Pinout: Standard color coding—Brown (GND), Red (VCC), Orange (Signal)—for error-free wiring.

• Case Material: High-strength plastic housing with reinforced mounting points to withstand high vibrations.

• Internal Potentiometer: High-precision internal feedback mechanism for accurate angular positioning.

• Dead Band: Ultra-narrow 1µs dead band ensures the motor responds to even the slightest change in signal.

• Weight-to-Power Ratio: Optimized 55g weight makes it suitable for medium-sized drones and walking robots.

• Control Frequency: Optimized for 50Hz (20ms period) PWM signals, the standard for hobbyist microcontrollers.

• Stall Protection: The digital controller includes minor current-limiting features to prevent immediate burnout during a physical block.

• Mounting Accessories: Includes multiple horn shapes (arm, cross, round) and rubber grommets with brass eyelets for vibration damping.

• Voltage Flexibility: Can be safely powered by a 2S LiPo battery (7.4V) through a BEC or regulator.

• Splash Resistance: The case design provides basic protection against dust and minor moisture, though it is not fully waterproof.
