MG995 Servo Motor Tower Pro Continuous Rotation (Full Metal with Brass Gear)
The MG995 Servo Motor by Tower Pro is a high-torque, full-metal gear servo designed for robust and reliable performance in a wide range of robotics and automation applications. Featuring a continuous rotation modification, this version of the MG995 operates more like a geared motor with positional feedback removed, allowing it to spin continuously in either direction based on PWM (Pulse Width Modulation) signals. This makes it ideal for use in mobile robot wheels, conveyor belts, and other projects where continuous rotational motion is required rather than angular positioning.
At the heart of the MG995 is a powerful motor coupled with brass and steel metal gears, providing both strength and durability under heavy loads. The torque output is impressive, rated at up to 11 kg·cm at 6V, making it capable of handling tasks that require substantial force. The motor operates on a voltage range of 4.8V to 7.2V, and it is typically controlled using standard PWM signals, making it compatible with most microcontrollers such as Arduino, Raspberry Pi, and other embedded systems.
A key feature of this servo is its full metal gear construction, which ensures long-lasting performance and resistance to wear compared to plastic gear models. It also includes dual ball bearings for smoother rotation and increased efficiency. With its relatively fast speed of 0.17 seconds/60 degrees at 6V (before conversion to continuous mode), it delivers responsive and stable movement.
In continuous rotation mode, the MG995 no longer centers on a fixed angle. Instead, sending a 1.5 ms PWM signal stops the motor, while shorter or longer pulses rotate it in clockwise or counterclockwise directions respectively. This versatility allows the servo to serve as a compact drive motor for small robotic platforms.
Overall, the MG995 continuous rotation servo is a cost-effective, durable solution for hobbyists and developers needing high-torque rotary motion in their projects.
