HiTec HS-82MG Standard Metal Gear Micro Servo
The HiTec HS-82MG is a compact metal gear micro servo designed for precision motion control in robotics, RC aircraft, and embedded systems requiring high torque output in a lightweight package. Professional engineers and hobbyists rely on this servo for applications demanding reliable angular positioning with minimal backlash and exceptional durability. This servo solves the critical challenge of achieving smooth, accurate mechanical actuation in space-constrained environments where standard servos are too large or heavy.
Product Overview
The HiTec HS-82MG operates on the principle of closed-loop servo control, utilizing an internal potentiometer feedback mechanism to maintain precise shaft position based on input PWM signals. The servo's metal gear train construction provides superior load-bearing capacity compared to plastic gear alternatives, enabling continuous operation under sustained mechanical stress without gear stripping or performance degradation. The internal circuitry processes control signals at standard RC servo frequencies (50Hz), translating voltage inputs into proportional angular movements with repeatability better than 1 degree across the full 60-degree operational range.
What distinguishes the HS-82MG is its optimized power-to-weight ratio and rapid response characteristics, making it ideal for applications requiring quick positional changes without overshooting. The servo features a standard 3-pin connector interface compatible with most microcontroller boards, RC receivers, and servo controllers. The metal gear construction ensures minimal wear over extended operational cycles, providing consistent torque delivery and positioning accuracy throughout the servo's operational lifespan, making it a cost-effective solution for long-term automation projects.

How to Use
To integrate the HiTec HS-82MG into your project, first connect the servo's three-pin connector to your control source: the red wire to positive power supply (4.8-6.0V DC), the black wire to ground, and the yellow/white wire to your PWM signal source (Arduino pin, RC receiver, or servo controller). Ensure your power supply can deliver at least 500mA peak current to prevent voltage sag during rapid movements. Before connecting to your microcontroller, verify the servo's neutral position by sending a 1.5 millisecond PWM pulse at 50Hz frequency, which corresponds to the 90-degree center position.
For Arduino integration, use the standard Servo library with analogWrite() or servo.write() functions, specifying angles from 0 to 180 degrees. When implementing multiple servos, distribute power connections using a servo power distribution board to prevent current spikes from affecting signal integrity. Always include a 100-microfarad capacitor across the power pins near the servo to smooth voltage transients. Test the servo's full range of motion (typically 0-180 degrees) without mechanical load first, then gradually introduce load while monitoring for stalling current. If the servo stalls for more than 2-3 seconds, reduce the load or check for mechanical binding, as continuous stalling generates excessive heat and reduces servo lifespan.
Frequently Asked Questions
What is the maximum continuous torque output of the HS-82MG servo?
The HiTec HS-82MG delivers 2.2 kg-cm of stall torque at 4.8V and 2.6 kg-cm at 6.0V. This represents the maximum holding force when the servo is commanded to a specific position against external load. For continuous applications, operate at 60-70% of stall torque to ensure thermal stability and extended servo lifespan. The servo can sustain these torque levels indefinitely at standard operating temperatures (0-60 degrees Celsius) provided adequate power supply current is available.
Can the HS-82MG servo be controlled directly from an Arduino microcontroller?
Yes, the HS-82MG is fully compatible with Arduino boards. Connect the yellow/white signal wire to any PWM-capable digital pin (pins 3, 5, 6, 9, 10, or 11 on Arduino Uno), then use the standard Servo library included in the Arduino IDE. The servo accepts PWM signals between 1.0 and 2.0 milliseconds at 50Hz frequency, with 1.5 milliseconds corresponding to the neutral 90-degree position. No external servo controller is required for basic applications, though servo shields are recommended when controlling multiple servos to manage power distribution efficiently.
What is the operational temperature range for the HS-82MG?
The HiTec HS-82MG operates reliably between 0 and 60 degrees Celsius. Performance characteristics remain consistent throughout this range, though response time may be slightly slower at lower temperatures due to lubricant viscosity changes. Extended operation above 50 degrees Celsius reduces servo lifespan, so ensure adequate heat dissipation in high-ambient-temperature environments. Do not operate below 0 degrees Celsius or above 70 degrees Celsius, as extreme temperatures can damage internal potentiometer and circuit components.
How much power does the HS-82MG servo consume during operation?
The servo draws approximately 100-150 milliamps during normal operation at idle position, increasing to 300-500 milliamps during active movement under load. Peak current consumption can reach 800 milliamps to 1 ampere during rapid acceleration or stall conditions. Ensure your power supply can deliver at least 1 ampere per servo to prevent voltage sag that degrades control accuracy. When operating multiple servos simultaneously, use a dedicated servo power distribution board rated for the combined current draw to maintain signal integrity.
Is the HS-82MG servo suitable for continuous rotation applications?
No, the HS-82MG is a standard positional servo limited to approximately 180 degrees of rotation (60 degrees in either direction from center). It is not designed for continuous 360-degree rotation. For continuous rotation requirements, consider HiTec's continuous rotation servo models. The HS-82MG is optimized for discrete positional control, making it ideal for applications requiring precise angle maintenance rather than continuous spinning motion.
