MG996R Metal Gear High Torque Digital Servo Motor
High-Speed 180° Rotation Servo for RC Cars, Helicopters, and Arduino Robotics
The MG996R is a hightorque digital servo motor featuring an allmetal gear train that delivers exceptional durability and precision. With a rotation angle of 180°, this servo is ideal for robotics, RC cars, boats, helicopters, and robot arms.
Powerful 11kg/cm Torque - Delivers high torque at 6V for demanding applications
AllMetal Gear Construction Aluminum 6061T6 metal gears for shockproof durability
Operating voltage is 4.8V to 7.2V with recommended 6V supply
Use a separate external power supply capable of 2.5A stall current
Do not power directly from Arduino 5V pin—this servo draws high current

Power Requirements
The MG996R requires substantial power:
- Running current: 500mA to 900mA at 6V
- Stall current: 2.5A at 6V
- Use a separate external power supply for stable operation
For Arduino projects, use a 5V 3A external adapter or battery pack
Add a capacitor (100µF or larger) near the servo to smooth power delivery
Insufficient power may cause servo twitching, stalling, or Arduino resets
Troubleshooting
Servo not moving:
- Check power supply provides at least 2.5A peak current
- Verify PWM signal connection (usually yellow/white wire)
- Avoid using Arduino 5V pin for power
Jittery or erratic movement:
- Add a large capacitor to the power supply lines
- Ensure stable voltage supply
- Check for loose wiring connections
Overheating or stalling:
- Reduce mechanical load on the servo
- Verify operating voltage does not exceed 7.2V
- Allow cooling between heavy usage cycles
