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.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: Do not use a 9V battery to power this servo. The high current draw of the MG996R will cause a 9V battery to voltage-drop instantly, leading to "jittering." Use a 6V 2A DC Adapter or a 6V Lead Acid battery for best results.

  • 18650 Cell: Use two 18650 cells in series (7.4V) paired with a Buck Converter set to 6V. This setup provides the high current (Amps) necessary for the servo to reach its maximum 11kg torque.

  • IC & Capacitor Tip: Always place a 470uF to 1000uF Electrolytic Capacitor across the servo's VCC and GND lines. This "decoupling" capacitor prevents the servo's motor noise from interfering with your Arduino’s logic. Pair it with a PCA9685 16-Channel Servo Driver if controlling multiple motors.

  • Related Products: We recommend pairing this with our Aluminum 25T Servo Horns, PCA9685 PWM Driver, and High-Current Jumper Wires.
