MG945 180 Degree High Torque Plastic Gear Servo Motor

The MG945 High Torque 180 Degree Plastic Gear Servo Motor is a robust standard-size actuator designed for high-stress robotic linkages, RC models, and industrial automation prototypes. Engineered to deliver exceptional holding capability, it provides a stall torque of up to 12 kg-cm at 6.0V across a 4.8V to 7.2V DC supply range. The internal drive mechanism combines a high-speed core motor with precision-engineered, wear-resistant plastic gears, ensuring smooth positional tracking, low running noise, and minimal inertia for dynamic motion profiles.

Built for effortless interfacing, this servo integrates seamlessly with 5V and 3.3V microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi using standard 50Hz PWM signal protocols. With full 180-degree proportional rotation, the MG945R is perfectly suited for multi-joint robotic arms, dual-axis pan-and-tilt camera platforms, automated steering mechanisms, and gripper controls. The attached 300mm 3-pin cable (Signal, VCC, GND) fits standard 2.54mm headers, servo expansion shields, and hobby radio receivers right out of the box.

Features:

• High Torque Delivery: Generates up to 12 kg-cm stall torque at 6.0V to manage heavy mechanical linkages with ease.
• Proportional 180° Range: Supports precise, repeatable angular positioning across a full 180-degree sweep via standard PWM pulses.
• Low-Friction Plastic Gear Train: Features precision-molded composite gears optimized for reduced mechanical wear and quiet operation.
• Broad Operating Voltage: Compatible with 4.8V to 7.2V DC power systems, including 4-cell NiMH packs and external BEC supplies.
• Microcontroller Friendly: Easily programmed via standard Arduino Servo libraries and ESP32 LEDC PWM channels without external drivers.
• Comprehensive Hardware Set: Includes 4 distinct output horns, mounting rubber grommets, brass eyelets, and installation screws.
