Product overview
The Zhuhai SV Tech Co., Ltd. AXR 7341 NG-D is a micro servo intended for lightweight fixed-wing control surfaces and compact linkage mechanisms. Its architecture combines a coreless motor, nylon gears and two bearings in a 19.6 × 8.3 × 19.85 mm body weighing 4.5 g. A 185 mm cable provides the electrical connection, with PWM control at 333 Hz. Integration requires matching the supply, pulse widths, mounting holes and servo-arm connection to the intended mechanism.
At 7.4 V, the servo has a stall torque of 1.8 kg·cm and a no-load speed of 0.07 s/60°, while rated torque is 0.3 kg·cm. Continuous-load sizing must account for rated torque and duty cycle. The permitted supply range is 4.8–8.4 V, with performance figures specified at 4.8, 6 and 7.4 V. Both a 1520 µs reference pulse and a 1500 µs position midpoint are specified, so neutral position and usable travel depend on the controller and delivered version.

| Stall-torque limitation | Stall torque is not a continuous-load rating; continuous-duty selection must account for rated torque and duty cycle.Continuous-load operation. |
| Voltage-range limitation | The operating voltage range defines permitted supply voltage. |
| Mounting dimensions | Drawings and tabulated dimensions may use different dimensional references; confirm the final mounting drawing and interface version before fabricating mounts.Mount fabrication and interface version. |
| Commissioning | Establish neutral position, movement direction and mechanical travel before progressively applying the working load.Initial setup with the load removed or limited. |
| Electrical and mechanical integration | Provide supply headroom for transient current, avoid cable voltage drop and reversed connections, and prevent sustained loading against mechanical stops.Installed power supply, wiring and mechanism. |
