Product overview
The Zhuhai SV Tech Co., Ltd. AXR 8462 MG-D is a mini servo for fixed-wing control surfaces and actuating mechanisms with limited installation space. Its construction combines an iron-core motor, stainless steel gears and two bearings. The body measures 23.5 × 11.8 × 27.9 mm, weighs 16.7 g and has a 250 mm cable. Installation requires allowance for the output-shaft position, mounting-hole spacing and connector clearance. Linkage geometry also matters: a longer servo arm reduces the force available at the output.
The servo operates on 4.8–8.4 V power with PWM control at an operating frequency of 333 Hz. At 7.4 V, it delivers 7.6 kg·cm stall torque and a no-load speed of 0.076 s/60°, with running and stall currents of 0.125 A and 1.8 A respectively. Rated torque is 2.5 kg·cm at 7.4 V. Continuous-load selection must account for rated torque and duty cycle, because stall torque cannot serve as a sustained-load rating. The supply needs headroom for transient current.
The reference pulse is 1520 µs, while the pulse-to-angle mapping places the midpoint at 1500 µs: 500 / 1500 / 2500 µs corresponds to -90 / 0 / 90°. Neutral and usable travel therefore require adjustment for the intended controller and delivered servo version. Establish the final mounting drawing and interface version before making mounting parts, as dimensional references can differ. Begin commissioning with the load removed or limited, establish direction and travel, and progressively apply load while avoiding sustained pressure against mechanical end stops.

| Continuous-load limitation | Stall torque cannot be used as a continuous-load rating; continuous operation requires consideration of rated torque and duty cycle. |
| Supply-range limitation | The voltage range defines the permitted supply range. |
| Mechanical integration | Check output-shaft position, mounting-hole spacing and connector clearance. Increasing servo-arm length reduces available output force. |
| Mounting references | Drawings and specifications may use different dimensional references; establish the final mounting drawing and interface version before fabricating mounting parts. |
| Commissioning | Establish neutral, movement direction and mechanical travel before progressively applying the working load.Initial commissioning with the load removed or limited. |
| Power and mechanical constraints | Allow supply headroom for transient current; avoid cable voltage drop, reversed polarity and sustained loading against mechanical end stops. |
