TowerPro MG959 Full CNC Alloy Case High Torque Servo Motor
The TowerPro MG959 is a professional-grade digital servo motor featuring a full CNC machined alloy case, delivering exceptional torque output of 15 kg/cm at 6V with rapid response times ideal for precision robotics and automation applications. Roboticists, drone engineers, and industrial automation technicians rely on this servo for demanding projects requiring high holding torque and minimal backlash in compact form factors. This servo solves the critical challenge of achieving sustained high-torque performance in weight-sensitive applications without compromising durability or control accuracy.
Product Overview
The TowerPro MG959 employs a coreless motor design paired with a sophisticated control circuit that enables smooth, jitter-free operation across its full 180-degree rotation range. The full CNC aluminum alloy case provides superior heat dissipation compared to plastic-housed alternatives, allowing the servo to maintain consistent performance during extended operational cycles. The integrated metal gears and reinforced servo horn mounting points ensure mechanical reliability even under sustained load conditions, making this servo suitable for continuous-duty applications in robotics, gimbal systems, and precision machinery.
What distinguishes the MG959 is its dual-bearing design that minimizes shaft wobble and backlash to approximately 1 degree, critical for applications requiring repeatable positioning accuracy. The servo accepts standard PWM control signals between 1000-2000 microseconds, integrating seamlessly with Arduino, Raspberry Pi, and professional servo controllers. The metal case construction not only enhances durability but also provides electromagnetic shielding, reducing interference susceptibility in multi-servo installations typical of robotic arms and hexacopter platforms.

How to Use
Begin by connecting the servo to your control system using three wires: red to positive voltage supply (4.8-6V), black to ground, and yellow/white to your PWM signal pin on your microcontroller. Ensure your power supply can deliver at least 1-2 amps during stall conditions to prevent voltage sag that affects servo response. Configure your PWM signal frequency to 50 Hz with pulse widths between 1000-2000 microseconds, where 1500 microseconds represents the center position. Most Arduino servo libraries handle this automatically when you specify the servo pin and desired angle in degrees.
Mount the servo using the four mounting holes on the case, ensuring the servo horn aligns with your mechanical linkage to avoid binding. When operating multiple servos simultaneously, use a dedicated servo power supply rather than microcontroller power to prevent voltage fluctuations that cause jitter and erratic behavior. Perform a calibration routine by commanding the servo to 90 degrees and mechanically adjusting your linkage so the output shaft centers precisely, then test the full 0-180 degree range to verify smooth operation. Monitor servo temperature during extended operation; if the case becomes too hot to touch, reduce duty cycle or add thermal management to prevent internal component degradation.
Frequently Asked Questions
What is the difference between the MG959 and standard plastic servo motors?
The MG959 features a full CNC machined aluminum alloy case instead of plastic housing, providing superior heat dissipation, electromagnetic shielding, and mechanical durability. The metal construction enables sustained high-torque operation without thermal throttling, while dual ball bearings reduce backlash to approximately 1 degree compared to 3-5 degrees typical in budget plastic servos. This makes the MG959 suitable for professional robotics and industrial applications where reliability and precision are non-negotiable.
Can the MG959 operate continuously at maximum torque without damage?
The MG959 can sustain continuous operation at rated torque (15 kg/cm at 6V) provided adequate power supply and thermal management are maintained. Monitor the servo case temperature during extended operation; the aluminum alloy housing dissipates heat effectively, but continuous stall conditions will generate significant heat. If the case becomes too hot to touch, reduce load or implement duty cycling. The metal gears and bearings are designed for continuous-duty applications, unlike plastic-geared servos which overheat and fail under similar conditions.
How do I integrate the MG959 with Arduino and what PWM frequency should I use?
Connect the servo to an Arduino PWM-capable pin (3, 5, 6, 9, 10, or 11 on Uno) using the Servo library. The standard Arduino Servo library automatically configures 50 Hz PWM frequency, which is ideal for the MG959. Use code like Servo myservo; myservo.attach(9); myservo.write(90); where write() accepts 0-180 degrees. The library internally converts degrees to the required 1000-2000 microsecond pulse range. For multiple servos, use separate pins and ensure your power supply can deliver sufficient current to all servos simultaneously.
What is backlash and why does the MG959 specification of 1 degree matter?
Backlash is the amount of free play or dead zone in the servo output shaft before mechanical movement begins. The MG959 exhibits approximately 1 degree of backlash due to its dual ball bearing design and precision metal gears, meaning when you command a direction change, the shaft moves 1 degree before load pickup occurs. This is critical for robotic arms where backlash accumulates across multiple joints, degrading end-effector positioning accuracy. Lower backlash servos like the MG959 are essential for precision tasks; budget servos with 3-5 degree backlash are unsuitable for demanding applications.
