HSR-2648CR Servo


This continuous rotation servo is based around the popular Hitec HSR-2645CRH, but with a 25 tooth output spline in order to conform with the majority of the hobby servo market. The servo also boasts an M3 x 0.5mm socket head servo screw for additional holding power and ease of use. Similar to the HSR-2645CRH, this servo rotates at a specific speed based on the signal received from the servo controller. Its speed is fully proportional meaning that the further the signal deviates from the center (1500µsec), the faster the servo will rotate. It can be difficult to control the speed of regular servos that have been modified to continuous rotation. However, the HSR-2648CR circuit was designed from the factory to drive the servo smoothly and with fine-control over the speed. Since the HSR-2648CR servo is digital, it's able to be tuned using a Hitec servo programmer. The programmable parameters allow you to tailor the servo to best fit your application. Excellent for compact sliders, winch mechanisms, small panning devices and wheel-drives on robots.
