DDSM400 All-in-One Direct Drive Servo Hub Motor for RC and Robotics

Jargon buster

Plain-language definitions for the technical terms used above.

encoder

A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.

IP54

An ingress protection rating meaning the enclosure has limited dust protection and is protected against water splashes from any direction. This matters because it gives a practical indication of how well the product may handle dusty or damp installations.

servo

A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.

servo motor

A motor module that moves to a commanded angle rather than simply spinning freely. It matters for robotics and mechanisms because it is useful for steering, arms, gates and other parts that need controlled position.

Torque

A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
