Product overview
The Zhuhai SV Tech Co., Ltd. AXR 7307 MG-D is a micro servo for light fixed-wing control surfaces and compact linkage mechanisms. Its coreless motor, metal gears and two bearings occupy a 19.6 × 8 × 21.8 mm envelope, with a weight of 7.1 g and an 80 mm cable. Integration requires matching the supply, mounting holes, servo-arm connection and control pulses. PWM control operates at 333 Hz, with a stated reference pulse width of 1520 µs.
Performance depends on supply voltage: stall torque rises from 1.8 kg·cm at 5 V to 3 kg·cm at 8.4 V, while no-load travel time falls from 0.075 to 0.052 s/60°. Continuous-load selection must use the rated 0.4 kg·cm at 6 V together with duty cycle. The 1500 µs position midpoint differs from the reference pulse, so neutral and usable travel depend on the controller and delivered version. Installation also requires allowance for transient current and avoidance of sustained mechanical end-stop loading.
