## Description

A high-torque brushless waterproof servo delivering up to 45 kg·cm of stall torque at 8.4V. The all-metal gear train and aluminium shell provide exceptional durability, while IP67-rated waterproofing — achieved through laminated circuit boards, waterproof gaskets, and breathable composite sealing — makes it suitable for outdoor and marine robotics applications. The brushless motor with MOS driver produces virtually silent operation with minimal jitter under load, making it an excellent choice for multi-joint robot projects. The servo supports 180° rotation within a 500–2500 µs pulse range and features an internal pulse lock function that holds position with a single PPM pulse, reducing processor overhead and extending service life. Key Features 45 kg·cm Stall Torque – At 8.4V (35 kg·cm at 6V) IP67 Waterproof – Sealed circuit board with breathable composite waterproof coating Brushless Motor – Quiet, low-jitter operation with MOS driver All-Metal Gears – Durable metal gear train for high-load applications Aluminium Shell – Strong, wear-resistant housing with good heat dissipation 180° Rotation – Precise angle control within 500–2500 µs pulse range No Internal Limit – Can physically rotate 360° without jamming Pulse Lock Function – Holds position with a single PPM pulse, reducing controller workload 1 µs Dead Zone – Highly responsive to small signal changes Dual Ball Bearings – Smooth output shaft rotation under load 1 Million+ Cycle Lifespan – Designed for long-term reliability Specifications Control System: PWM (digital signal processing) Working Voltage: 6.0–8.4V Max Torque: 35 kg·cm at 6V / 45 kg·cm at 8.4V No-Load Speed: 0.12 sec/60° at 6V / 0.11 sec/60° at 8.4V No-Load Current: 450 mA at 6V / 600 mA at 8.4V Stall Current: 5000 mA at 6V / 7000 mA at 8.4V Pulse Width Range: 500–2500 µs Rotation Angle: 180° Dead Zone: 1 µs Motor Type: Brushless (MOS driver) Bearings: 2× ball bearings Gear Material: All metal Shell Material: Aluminium Waterproof Rating: IP67 Operating Temperature: −20°C to +60°C Service Life: >1,000,000 cycles Dimensions: 40 × 20 × 40.5 mm Ideal For Multi-joint walking robots and robotic arms RC boats and marine robotics Outdoor and all-weather robot projects DIY robot cars and tracked vehicles Professional development and research applications Package Contents 1× 45 kg Torque Brushless Waterproof Servo 1× Servo horn and screw pack Warning: This servo draws up to 7A under stall conditions at 8.4V. Ensure your power supply can deliver sufficient current, especially when running multiple servos.
