Product overview
The Zhuhai SV Tech Co., Ltd. AXR 7350 MG-D is a miniature servo intended for lightweight fixed-wing control surfaces and compact linkage mechanisms. Its coreless motor and metal gears occupy a 19.6 × 8.3 × 19.85 mm package weighing 5.5 g, with a 185 mm cable for integration. It accepts 4.8–8.4 V power and PWM control at 333 Hz. Selection depends on the control-surface load, linkage lever arm and required movement speed, alongside the available installation space.
At 7.4 V, the servo has a stall torque of 1.8 kg·cm, a no-load speed of 0.07 s/60° and a rated torque of 0.4 kg·cm. Stall torque is unsuitable as a continuous-load rating; duty cycle also matters. Integration requires attention to the 1520 µs reference pulse and the separately specified 1500 µs position midpoint. Center and usable travel depend on the controller and delivered version. Mount fabrication requires the final installation drawing, while the power supply needs headroom for transient current.

| Center and travel qualification | The reference pulse is 1520 µs, while the position midpoint is 1500 µs; center and usable travel require confirmation for the controller and delivered version.Controller and delivered servo version determine the center position and usable travel. |
| Stall torque limitation | Stall torque cannot be treated as a continuous-load rating; continuous-load selection must account for rated torque and duty cycle.Continuous-load selection. |
| Voltage performance coverage | The permitted voltage range does not imply test data at every voltage.Operation within the permitted supply-voltage range. |
| Mounting dimensions qualification | Drawing and specification dimensions may use different reference points; confirm the final mounting drawing and interface version before fabricating mounts.Fabrication of mounting components. |
