Product Overview
The XQ-RS9350MB is a 390kg-cm class industrial brushless actuator engineered for the most demanding positioning tasks on a modern production floor. Its reinforced toughened steel gear train converts the output of a high-efficiency industrial brushless motor into a staggering 390kg.cm of stall torque, giving system integrators enough mechanical headroom to drive heavy lift columns, palletizing linkages and multi-axis robot joints without bolting on a secondary reduction stage.
Powering that torque is a flexible 24.0-30.0V platform. Paired with a 12-bit contactless magnetic encoder, the RS9350MB delivers smooth, low-ripple motion across the entire voltage window, so the same actuator can be standardized across 24V mobile platforms and 30V industrial supplies. At the top of the range it produces the full 390kg stall torque, while 28V and 24V operation still yield 360kg and 320kg respectively – a predictable torque curve that makes mechanical sizing simple.
Integrating the unit into an existing factory network is equally straightforward. The RS9350MB communicates over MODBUS-RTU (RS485), so it can be dropped directly onto the fieldbus that mainstream PLCs, HMIs and robot controllers already speak. Register-level access exposes position commands alongside temperature and current-load telemetry, which means an engineer can commission a new node in minutes instead of writing custom motor-control firmware. For smart factory automation, that standardized interface is what turns a powerful actuator into a scalable, networkable motion asset.

Key Technical Highlights
Standard MODBUS-RTU protocol ensures seamless integration with industrial PLC systems and multi-axis automated production lines.
Standardized PLC Integration
MODBUS-RTU over RS485 puts the RS9350MB on the same industrial bus your PLC already uses. Multi-node daisy-chaining, standardized register mapping and real-time telemetry replace proprietary PWM wiring, cutting commissioning time and letting a single controller supervise dozens of joints on one network.
Monster 390kg Torque
A reinforced toughened steel gear train multiplies brushless motor output into 390kg.cm of stall torque in a 68.0*35.0*120.0mm body weighing just 690g. That density of force lets heavy industrial joints move under load without a second reduction stage, saving weight and mechanical complexity.
Advanced Brushless Reliability
A high-efficiency industrial brushless motor eliminates brush wear and the maintenance interval that comes with it. Combined with a 12-bit contactless magnetic encoder, it holds precise absolute positioning and consistent torque across the full 24.0-30.0V range for far longer duty cycles than brushed alternatives.
Giant CNC Thermal Armour
The full CNC-machined 7075 aluminum case acts as both a rigid structural member and a large heat sink. It spreads motor and driver heat away from the windings during continuous high-torque duty, keeping performance stable in heavy industrial machinery where sustained loads and vibration are the norm.
Frequently Asked Questions
