Product Overview
The XQ-RS9350D is engineered for the most demanding heavy-duty automation work. Driven by a high-efficiency industrial brushless motor and reinforced toughened steel gearing, it produces an exceptional 390 kg.cm (5,416 oz-in) stall torque at 30V \u2014 enough to drive large robotic arms, heavy rotary joints and industrial positioning stages without an extra gear reduction stage. That torque density means fewer moving parts, a simpler mechanical design and a shorter bill of materials for your machine.
The unit is built around a 24.0-30.0V wide-voltage power platform. At 24V it delivers 320 kg.cm, at 28V it climbs to 360 kg.cm, and on a full 30V rail it reaches its rated 390 kg.cm peak \u2014 all at a consistent 0.16s response speed. Integrators can therefore run the same actuator from a standard 24V industrial supply or push it to maximum output on 30V, leaving genuine headroom for voltage sag, long cable runs and brown-out conditions on the factory floor.
Communication is handled by an RS485 serial bus interface using differential signaling. Compared with traditional PWM control, RS485 provides noise-immune, long-distance, multi-node networking with complete telemetry returned from the actuator \u2014 including position, temperature and current load. In electrically noisy factory environments the differential pair keeps every command packet intact, so motion commands stay precise even across long daisy-chained bus segments.

Key Technical Highlights
Industrial RS485 Bus Reliability
Every XQ-RS9350D speaks RS485. A differential serial bus with hardware-level arbitration lets you daisy-chain multiple actuators onto one industrial network, run cables over long distances and read back real-time telemetry \u2014 position, temperature and current load \u2014 from every node. No shielded PWM harnesses, no analog drift, no guessing.
Pro Tip: For traditional PWM control requirements, see our standard S9350D model.
Monster 390kg Torque
A 390 kg.cm (5,416 oz-in) stall torque rating at 30V puts the RS9350D in a class of its own. Reinforced toughened steel gears and an industrial brushless motor let it hold heavy loads statically and accelerate large inertia without stalling \u2014 ideal for heavy-duty robotic joints, lift mechanisms and industrial rotary tables.
Advanced Magnetic Precision
Position feedback comes from a 12-bit contactless magnetic encoder. With no wearing contacts and no optical path to foul, the sensor holds its resolution and repeatability across millions of cycles, so closed-loop positioning stays tight even after long shifts of continuous motion.
Giant CNC Thermal Armour
The full CNC-machined 7075 aluminum case acts as structural chassis and thermal radiator at the same time. Rigid, finned and dimensionally stable, it draws heat out of the motor and driver stage, letting the RS9350D sustain high-torque duty cycles inside heavy industrial enclosures without thermal throttling.
Real-time telemetry feedback (position/temperature) to prevent downtime in high-load robotic systems.
Frequently Asked Questions
A: Absolutely. The full CNC 7075 aluminum case and toughened stainless steel gears are specifically engineered to handle high-frequency vibrations and extreme mechanical shocks. The RS485 protocol ensures your command remains precise even in the most electrically noisy factory environments.
A: At this torque scale, signal integrity and feedback are critical. RS485 allows for long-distance, multi-node networking with mission-critical telemetry (position, temperature, current load), which traditional PWM cannot offer over long cable runs in a factory setting.
A: It uses a high-strength industrial output shaft with a 25T-\u03c69.95mm spline interface, ensuring compatibility with heavy-duty robotic arms and professional-grade industrial fittings.
