Product overview
Zhuhai SV Tech Co., Ltd.’s AXR 6801 TG is a standard servo for model steering, control-surface movement and mechanical actuation. Its physical configuration combines an iron-core motor, nylon gears and one bearing in a 40 × 20 × 36.3 mm body weighing 40.2 g. A 250 mm cable provides the connection reach for installation. Integration requires matching the supply, PWM pulse settings, mounting holes and servo-arm connection. Mounting fabrication also requires the final installation drawing and interface version because dimensional reference points can differ.
The servo accepts 4.8–8.4 V power and specifies a 333 Hz operating frequency. At 7.4 V, it delivers 7.3 kg·cm stall torque with a no-load speed of 0.114 s/60°, while rated torque is 2.5 kg·cm. Stall torque is unsuitable as a continuous-load rating; sustained operation requires consideration of rated torque and duty cycle. Control settings also need attention: the reference pulse is 1520 µs, while the angle mapping places zero degrees at 1500 µs. Neutral and usable travel depend on the controller and delivered version.
