Description

Waterproof 45kg 8.4V Coreless High-Torque Digital Servo with Full Metal Gears and IP67 Protection – Heavy-Load Precision for Robotics, RC Crawlers, and Industrial Mechanisms

This 45kg coreless digital servo is engineered for extreme torque applications where strength, precision, and fast response are essential. The coreless motor reduces rotational inertia, providing quicker acceleration, smoother movement, and higher efficiency compared to traditional brushed servo motors. With an 8.4V high-voltage drive, it delivers powerful output suitable for steering heavy RC crawlers, robotic actuators, industrial joints, and large-scale mechanical assemblies.

Constructed with a complete metal gear system, the servo ensures long-term durability under demanding loads. The CNC-machined aluminium case improves heat dissipation and structural rigidity during continuous operation. Its IP67 waterproof rating makes it ideal for wet, dusty, muddy, and outdoor all-terrain environments, ensuring dependable performance in challenging conditions. Digital control electronics enhance accuracy, repeatability, and minimal deadband for fine-positioning tasks.

Key Features:

45kg High Torque Output: Supports heavy steering loads, robotic lifting, and industrial-grade motion control.
Coreless Motor Technology: Delivers fast reaction speed, smooth rotation, and reduced vibration.
IP67 Waterproof Rating: Fully protected against dust and temporary water immersion for outdoor reliability.
8.4V High-Voltage Performance: Increased efficiency, torque, and operating speed under demanding conditions.
Full Metal Gear Train: High-strength gears for maximum durability and heavy-duty applications.
CNC Aluminium Alloy Case: Excellent thermal stability and mechanical strength.
Advanced Digital Control: Accurate positioning, low deadband, and stable operation for precision tasks
