The Hitec HSR-1425CR Continuous Rotation Servo is a precision-engineered standard servo modified for continuous 360° rotation, making it ideal for robotics applications that require smooth, controlled movement. Unlike standard servos, it has no internal positional feedback, allowing it to operate like a geared DC motor with the convenience of standard servo control signals.
Built with nylon gears and dual ball bearings on the output shaft, the HSR-1425CR offers durability for extended operation. Its compact size, light weight, and robust construction make it a top choice for small wheeled robots, automation projects, and educational robotics kits.
By using a PWM control system with a 1500µs neutral point, speed and direction can be easily adjusted. This servo delivers excellent torque output and steady performance over a wide voltage range (4.8–6.0V).
