Product Overview
The XQ-S9350D is a 30V-class industrial brushless servo engineered for the heaviest motion tasks in factory automation, delivering a massive 390 kg.cm (5,416 oz-in) stall torque from a compact 68.0 x 35.0 x 120.0 mm envelope weighing just 690 g. Built on XQ-POWER’s high-efficiency industrial brushless motor platform, it replaces oversized brushed and hydraulic actuators on robotic gantries, heavy joint arms and high-load positioning axes.
Torque scales cleanly across the 24.0V – 30.0V power platform: 320 kg.cm at 24.0V, 360 kg.cm at 28.0V and the full 390 kg.cm at 30.0V, each with a 0.16 s transit. That headroom lets system integrators standardise on a single actuator class across an entire machine instead of mixing motor sizes, while the lower current draw at equal torque keeps heat rise and power-supply sizing firmly under control.
Industrial reliability comes from the mechanical package: a reinforced toughened steel gear train, a giant CNC-machined 7075 aluminium thermal armour case and a 12-bit contactless magnetic encoder that never wears out. PWM, CAN Bus and RS485 interfaces with differential bus signalling make the XQ-S9350D a drop-in node on existing PLC, motion-controller and factory network architectures.

Key Technical Highlights
Ultra-High 30V Power Efficiency
The 30V power stage is what makes 390 kg.cm practical in a 690 g actuator. Higher bus voltage means the same mechanical output is produced with lower current, so copper losses, heat rise and supply current limits all drop together. The result is a high torque-to-weight ratio with minimal thermal throttling, plus the high-bandwidth response needed for synchronized movement in heavy-duty robotic gantries where 12V and 24V systems simply run out of headroom.
Giant CNC 7075 Thermal Armour
Aerospace-grade 7075 aluminium is CNC-machined into a structural case that does three jobs at once: it dissipates the heat generated by continuous high-torque duty, it stiffens the entire gearbox against deflection under load, and it shields the encoder and control electronics from the mechanical shocks and high-frequency vibration typical of heavy industrial joints. This is the difference between a hobby servo and a production-floor actuator.
Industrial Multi-Bus Integration
PWM, CAN Bus and RS485 are all supported on the same unit. Differential bus signalling (RS485/CAN) keeps command timing precise even in high-EMI factory environments, so the XQ-S9350D integrates directly with PLCs, motion controllers and existing factory networks without external signal conditioning – and without rewriting the machine’s communication layer.
Reinforced Stainless Steel Drivetrain
The gear train is built from reinforced toughened steel rather than sintered or plastic gearing, so it withstands extreme mechanical shocks, stall events and the high-frequency vibration of heavy automation. It drives a specialized high-strength industrial output shaft with a 25T-11.8mm spline interface, ensuring high-torque transfer compatibility with professional-grade industrial fittings and heavy robotic arms.
Exceptional vibration resistance and mechanical stability for 24/7 industrial automation.
