Product overview
The AXR 9497 MG-D from Zhuhai SV Tech Co., Ltd. is a miniature servo for fixed-wing control surfaces and mechanisms with limited installation space. Its coreless motor, stainless steel gears and two bearings fit within a 23 × 12 × 26.8 mm body weighing 19.2 g, with a 250 mm cable. Integration requires checking output-shaft position, mounting-hole spacing and connector clearance. Servo-arm length also affects linkage selection: a longer arm reduces available output force. Confirm the final mounting drawing and interface version before fabricating installation parts, since dimensional references may differ.
The servo operates at 4.8–8.4 V with PWM control and a 333 Hz operating frequency. At 8.4 V, stall torque is 13.2 kg·cm, no-load speed is 0.066 s/60° and stall current is 2.5 A; rated torque is 4 kg·cm. Continuous-duty selection must consider rated torque and duty cycle rather than treating stall torque as a sustained load. The 1520 µs reference pulse differs from the 1500 µs position midpoint, so neutral and usable travel require confirmation for the controller and delivered version. Initial setup requires removed or limited load, with supply headroom for transient current.

| Neutral position and usable travel | The reference pulse is 1520 µs and the position midpoint is 1500 µs. Confirm neutral position and usable travel for the controller and delivered version.Controller and delivered servo version. |
| Continuous-load limitation | Stall torque cannot serve as a continuous-load rating; continuous-duty selection must consider rated torque and duty cycle. |
| Supply-range qualification | The operating voltage range defines permitted supply voltage. |
| Installation space and linkage | Check output-shaft position, mounting-hole spacing and connector clearance. Increasing servo-arm length reduces available output force. |
| Mounting dimensions qualification | Drawings and specifications may use different dimensional references. Confirm the final installation drawing and interface version before fabricating mounting parts. |
| Commissioning | Confirm neutral position, movement direction and mechanical travel before progressively checking the working load.Initial setup with the load removed or limited. |
| Electrical and mechanical integration | Allow supply headroom for transient current and avoid cable voltage drop, reverse connection and sustained loading against mechanical stops. |
