MG995 Servo Motor Tower Pro Continuous Rotation (Full Metal Gear)
The MG995 Tower Pro Continuous Rotation Servo Motor is a high-performance, durable servo designed for applications that require full 360-degree continuous motion. Unlike standard servo motors that rotate to a specific angle (e.g., 0° to 180°), this version of the MG995 is modified to provide continuous rotation, making it ideal for wheeled robots, conveyor systems, mobile platforms, and other projects requiring bidirectional speed control.
Equipped with full metal gears, including strong brass and steel components, the MG995 is built to handle mechanical stress and heavy loads without gear wear or failure. Its robust internal structure allows for higher torque output — up to 12 kg·cm at 6V — which is particularly beneficial for mobile robotics or lifting mechanisms. The inclusion of dual ball bearings enhances smooth motion and longevity, even under frequent or high-load usage.
This servo is controlled using a PWM (Pulse Width Modulation) signal, but instead of controlling position, the pulse length controls the speed and direction of rotation. A 1.5 ms pulse stops the motor, pulses shorter than 1.5 ms make it spin in one direction, and pulses longer than 1.5 ms make it spin in the opposite direction. The further the pulse deviates from 1.5 ms, the faster the motor spins.
The MG995 continuous rotation servo operates at a voltage range of 4.8V to 7.2V, with a typical operating speed of around 0.14–0.20 sec/60° equivalent, depending on voltage. Its standard 3-wire interface (orange for signal, red for VCC, and brown for GND) makes it easily compatible with Arduino, Raspberry Pi, and RC controllers.
In summary, the MG995 Continuous Rotation Servo Motor is a powerful, reliable, and affordable solution for motion control in DIY robotics, smart automation, and RC-based projects.
Features:
- Full 360° Continuous Rotation: Moves freely in either direction — ideal for wheels, conveyor belts, or rotating platforms.
- Speed and Direction Control via PWM: Easily control how fast and in which direction it spins using simple pulse signals.
- Strong and Durable Metal Gears: Built with full metal gears that last longer and handle more stress than plastic ones.
- Powerful Torque for Heavy Loads: Can move or drive heavier objects with ease — great for mobile robots or lifting systems.
- Stable and Smooth Operation: Dual ball bearings reduce noise and friction, giving a smooth and reliable motion.
- Plug-and-Play with Arduino & RC: Connects easily to common platforms like Arduino, Raspberry Pi, or RC controllers — no complicated setup.
- Stays in Motion Until You Tell It to Stop: Unlike regular servos, it keeps spinning as long as you send the right signal.
- Compact and Fits Anywhere: Small enough to fit in tight spaces while still offering strong output.
- Affordable and Beginner-Friendly: Offers high performance for a low cost, making it ideal for students, hobbyists, and prototype projects.
- Great for DIY Robotics and Smart Projects: Perfect for smart cars, automatic doors, animatronics, and other creative builds.
