  • No-Load Speed – 280 RPM
  • Gear Type – Metal
  • Encoder – Built-in speed encoder

Ideal For

  • Small mobile robot platforms
  • Wheeled and tracked vehicles
  • Automation and mechanical systems requiring speed feedback
  • DIY projects needing a compact geared motor with encoder

Package Contents

  • 1× GA25-370 DC Gear Motor with Speed Encoder

Jargon buster

Plain-language definitions for the technical terms used above.

closed-loop control
Closed-loop control means the system uses feedback, such as motor position or speed, to adjust its output automatically. This matters because it can keep a motor moving accurately even when the load changes, unlike simple open-loop control.
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.
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.
