Description
The 5203 Series Yellow Jacket Planetary Gear Motor (188:1, 30 RPM, 3.3–5V Encoder) is a high-torque brushed DC motor engineered for robotics and motion-control applications. It combines a durable steel planetary gearbox with a precision Hall-effect quadrature encoder, delivering exceptional torque output and accurate speed feedback.
Designed around the goBILDA build system, the motor features a robust 8 mm REX output shaft and M4 threaded mounting holes on the 16 mm square goBILDA pattern, ensuring seamless integration with a wide range of mechanical components. Its 188:1 gear ratio provides a low-speed, high-torque output ideal for drive systems, arms, or heavy-duty mechanisms.
This motor offers high reliability, smooth performance, and easy connectivity through 3.5 mm bullet connectors and a 4-position JST encoder connector.
