25GA370 12V 280RPM DC Gear Motor with Encoder

Overview 

The 25GA370 is a high-performance geared motor that strikes the perfect balance between speed and torque. Unlike cheap plastic hobby motors, this unit features a full-metal gearbox for longevity and a built-in magnetic encoder. The encoder provides real-time feedback, allowing your robot to drive in a perfectly straight line, turn exactly 90 degrees, or maintain a constant speed regardless of the terrain or load.

Key Features 

• Integrated Hall Encoder: Dual-channel (Phase A & B) feedback for measuring both speed and direction of rotation.

• High-Torque Metal Gearbox: Rugged construction designed to handle heavy mobile robot chassis without stripping gears.

• 280 RPM Output: Optimized for medium-speed robots that require enough “oomph” to climb small obstacles or ramps.

• D-Shape Shaft: Features a 4mm D-shaped output shaft to prevent wheel slippage under high load.
