Product overview
The AXR 8830 MG-D from Zhuhai SV Tech Co., Ltd. is a standard servo for RC steering, control surfaces and mechanisms. Its configuration combines an iron-core motor, stainless steel gears and two bearings in a 40 × 20 × 36.6 mm package weighing 64 g. A 300 mm lead provides connection reach within the installation. Mechanical integration requires checking the mounting pattern and arm connection, with the final mounting drawing and interface version established before machining mating parts because dimension datums may differ.
The servo accepts 4.8–8.4 V and uses PWM control at 333 Hz. At 8.4 V, stall torque is 40 kg·cm, no-load speed is 0.147 s/60° and stall current is 6.1 A; rated torque is 13 kg·cm at 7.4 V. Stall torque cannot serve as a continuous load rating. Controller setup must resolve the 1520 µs reference pulse against the 1500 µs position centre and establish usable travel. Commissioning calls for an initially removed or limited load, gradual load validation and provision for transient current.

| Pulse width and angle | 500 / 1500 / 2500 µs → -90 / 0 / 90° |
| Torque limitation | Stall torque is not a continuous load rating; mechanism sizing must account for rated torque and duty cycle. |
| Neutral and travel qualification | The 1520 µs reference pulse differs from the 1500 µs position centre; neutral setting and usable travel require confirmation for the controller and delivered version. |
| Mounting qualification | Drawing and tabulated dimensions may use different datums; mating parts require the final mounting drawing and interface version. |
| Electrical and mechanical integration limits | Integration must accommodate transient current and prevent voltage drop, reversed connections and sustained contact with mechanical stops. |
