Product overview
The Zhuhai SV Tech Co., Ltd. AXR 7308plus MG-D is a micro servo for lightweight fixed-wing control surfaces and compact mechanisms. Its construction combines a coreless motor, metal gears and two bearings in a body measuring 23.5 × 8 × 16.6 mm and weighing 10.2 g. Cable length is 185 mm. It accepts PWM control at 333 Hz and operates from 3.8–8.4 V. Integration requires checking the supply, signal pulse widths, mounting-hole positions and servo-arm connection against the intended installation.
At 8.4 V, stall torque is 6.5 kg·cm, no-load speed is 0.06 s/60° and rated torque is 1.4 kg·cm. Stall torque cannot serve as a continuous-load rating; sustained operation requires consideration of rated torque and duty cycle. The 1520 µs reference pulse and 1500 µs position midpoint require confirmation of neutral and usable travel with the controller and delivered version. Drawing dimensions may use different reference points, so mounting-part fabrication requires the final installation drawing and interface version.
