AXR 9742 MG-D

Product and selection

Low-profile housings suit chassis with limited installation height. Fast steering depends on servo speed, tyre loads, steering geometry and voltage drop together. Verify spline, arm and receiver-signal compatibility, and set travel limits to prevent the linkage from holding the servo stalled.

Performance by voltage

Stall torque is not a continuous load rating. Consider rated torque and duty cycle when sizing the mechanism. The operating range specifies allowable supply voltage; it does not imply that test data exist at every voltage.

Control signal

PWM

Operating frequency

333 Hz

Reference pulse width

1520 µs

Pulse width and angle

500 / 1500 / 2500 µs → -90 / 0 / 90°

The source lists a 1520 µs reference pulse and a 1500 µs position centre. Confirm the neutral setting and usable travel for the controller and delivered version.

Mounting dimensions

Drawing and tabulated dimensions may use different datums. Confirm the final mounting drawing and interface version before machining mating parts.

Installation and integration

Check the supply, pulse width, mounting pattern and arm connection first. Commission with the load removed or limited, verify centre position, direction and mechanical travel, then validate the working load gradually. Allow for transient current and prevent voltage drop, reversed connections and sustained contact with mechanical stops.
