XQPOWER’s 9-Series (S9xxxD) is a premier industrial heavy-duty actuator platform engineered for mission-critical applications. By integrating Brushless DC (BLDC) motors with Absolute Magnetic Encoders, XQPOWER delivers unparalleled reliability and precision across PWM, TTL Serial, and CAN bus interfaces.
1. The Brushless Advantage: Industrial-Grade Reliability
Compared to traditional brushed motors, XQPOWER’s brushless FOC (Field-Oriented Control) drive offers significant operational benefits:
- Extended Service Life (MTBF 2,000h+): The absence of carbon brush friction eliminates mechanical wear, preventing motor burnout during continuous long-term operation. Ideal for industrial robotic joints requiring 24/7 duty cycles.
- Superior Thermal Efficiency: Optimized for 8.4V high-voltage systems, these servos exhibit minimal temperature rise even under heavy-load stall conditions, maintaining peak performance without thermal throttling.
- FOC Vector Drive Precision: The advanced FOC algorithm ensures ultra-smooth motion at low speeds and immediate torque response. The “Hard Locking Torque” stabilizes massive loads and resists high-frequency impact forces.
- Vibration & Shock Resistance: Unlike brushed components prone to contact failure, the brushless structure is highly resilient, making it the standard for UAVs, AGVs, and tactical equipment.
2. Absolute Magnetic Encoder vs. Potentiometer
XQPOWER utilizes non-contact magnetic sensing technology to overcome the physical limitations of traditional servos:
- Zero-Drift Accuracy: Traditional potentiometers suffer from wiper wear, leading to jitter and zero-point offset. XQPOWER’s non-contact Magnetic Encoder maintains absolute positioning accuracy after millions of cycles.
- 14-Bit High-Resolution Sensing: Delivering up to 16,384 positions per revolution, the encoder enables sub-degree precision for delicate robotic arm maneuvers and high-end gimbal stabilization.
- 360° True Absolute Positioning: Unlike limited-rotation sensors, our magnetic encoders support multi-turn absolute detection. The servo identifies its exact coordinates instantly upon power-up without needing a “homing” sequence.
- IP67 Environmental Protection: The non-contact design is inherently resistant to dust, moisture, and vibration, aligning with the rigorous demands of industrial automation.
3. TTL Serial Bus & Advanced Telemetry
The TTL Serial version represents the transition from simple actuators to intelligent networked nodes:
Programmable Motion Profiles: Parameters such as speed limits, torque constraints, soft-start ramps, and angle offsets can be adjusted via software (registers), eliminating the need for hardware-level resistors.
Simplified Daisy-Chain Topology: Multiple servos can be linked via a single TTL bus using unique ID addressing. This drastically reduces wiring complexity in multi-joint humanoid or hexapod robotics.
Real-time Bi-directional Feedback: The controller receives comprehensive telemetry, including Real-time Angle, Current, Voltage, Internal Temperature, and Fault Diagnostics. This enables sophisticated closed-loop monitoring and over-load protection.

4. 9-Series (S9xxxD) Industrial Build Quality
Purpose-built for heavy-duty applications (e.g., S9150D, S9350D, S9750D):
- Heavy-Duty Hardware: Features CNC-machined full aluminum alloy housing and reinforced stainless steel gear sets. Torque outputs range from 50kg·cm to a massive 900kg·cm.
- All-Weather IP67/IP68 Rating: Fully sealed military-grade structure for outdoor, dusty, or shallow underwater operations.
- Versatile Integration: Compatible with PWM, TTL Serial, and CAN Bus, ensuring seamless interfacing with PLCs, microcontrollers, and professional UAV flight controllers.
