Dc Gear Motor With Magnetic Linear Encoder jGA25-370 (170RPM-6V)

The JGA25-370 DC Gear Motor with Magnetic Encoder bridges the gap between simple DC motors and complex stepper motors by offering high-torque continuous rotation with precise positional feedback. Built around a standard 370-size DC motor and a 25mm all-metal gearbox, this motor operates at a nominal 6V to deliver a smooth 170 RPM at the output shaft.

What sets this motor apart is its integrated dual-channel Hall-effect magnetic encoder. By reading the quadrature pulse outputs (Channel A and Channel B), microcontrollers like Arduino, ESP32, or Raspberry Pi can calculate the motor’s exact speed, direction of rotation, and distance traveled. This makes it a perfect component for balancing robots, precise maze-solvers, PID speed controllers, and advanced automated machinery where blind rotation is not enough.

Key Features

• Closed-Loop Control Ready: The built-in magnetic Hall-effect encoder allows for precise speed tracking (RPM), position monitoring, and rotational direction sensing.

• All-Metal Gearbox: Highly durable internal metal gears ensure a long lifespan, reduced wear, and the ability to handle stalls and high-torque loads better than plastic counterparts.

• Standard D-Shaft: Features a 4mm D-shaped output shaft, ensuring a slip-free connection with a wide variety of wheels, pulleys, and shaft couplers.

• Compact & Powerful: The 25mm diameter profile makes it easy to mount in tight chassis spaces while still delivering substantial pushing power for medium-sized robots.

• 6-Pin Interface: Comes with a neat 6-pin wiring terminal separating motor power from encoder logic, ensuring clean signals and safe microcontroller integration.
