Product Overview
The XQ-RS9150D is a 180kg.cm ultra-torque industrial brushless actuator engineered for heavy-duty automation, large robotic joints and industrial motion systems. A brushless BLDC motor paired with a reinforced toughened steel gear train produces a genuine 180kg.cm (2500 oz-in) stall torque at 16.8V while keeping the whole unit to just 452g.
Control is handled over an RS485 serial bus with differential signaling, which gives the actuator exceptional immunity to electrical noise on factory floors and supports long cable runs and multi-node daisy-chain topologies. Combined with a full-CNC aluminium housing and contactless magnetic feedback, the XQ-RS9150D is built for continuous, industrial-grade reliability in demanding automation environments.

Key Technical Highlights
1. Industrial RS485 Bus Reliability
Differential RS485 signaling rejects common-mode electrical noise generated by motors, VFDs and welding equipment on the factory floor. Nodes can be daisy-chained over a single twisted pair with unique IDs, enabling long-distance, multi-axis control from one host controller.
2. Monster 180kg Torque & 4S Efficiency
At 16.8V (4S HV) the XQ-RS9150D delivers a massive 180kg.cm — around 2500 oz-in — of stall torque, enough to drive large mechanical joints, heavy gantries and industrial grippers without external gearing. The brushless motor maintains high efficiency and low heat build-up even under sustained heavy loads.
3. Advanced Magnetic Precision
A contactless magnetic encoder provides high-resolution, drift-free position feedback with no wearing potentiometer tracks, so accuracy stays stable across millions of high-torque cycles and the service life is dramatically extended.
4. Heavy-Duty CNC Armour & Socket Interface
The 64mm full-CNC aluminium case doubles as a heatsink for the brushless motor and gear train. A professional socket interface keeps wiring secure, correctly keyed and quickly serviceable, supporting long-term industrial deployment.
Engineering selection note: Choose the XQ-RS9150D where motion commands and feedback must cross long, electrically noisy cable runs: the differential RS485 link lets several units daisy-chain on one twisted pair using unique node IDs, so one host controller can address a complete multi-axis machine. Size the axis against the published curve — 116 kg.cm at 8.4V, 160 kg.cm at 12.6V and 180 kg.cm (2500 oz-in) at 16.8V, at 0.20, 0.17 and 0.14 sec/60° — all inside a 64mm, 452g full-CNC body with a contactless magnetic encoder. Where the controller needs register-level MODBUS-RTU access instead of a plain serial bus, the XQ-RS9150MB is the same 180kg.cm platform with a MODBUS-RTU register map.
Frequently Asked Questions
A: RS485 uses a differential twisted pair, so electrical noise that couples onto the cable is cancelled at the receiver. This allows reliable command and feedback traffic over long cable runs and through electrically noisy industrial environments, and lets multiple actuators share one bus via unique node IDs.
A: Yes. The brushless BLDC motor, reinforced toughened steel gears, contactless magnetic encoder and full-CNC aluminium housing are all specified for continuous industrial duty. With adequate supply current and correct thermal mounting, the unit is designed for round-the-clock operation in automation and robotic systems.
