The 12V Pololu 150:1 Micro Metal Gearmotor with Extended Motor Shaft is a compact, high-power brushed DC motor designed for precision robotics and automation projects. Built with long-life carbon brushes and a durable 150.58:1 all-metal gearbox, this motor ensures excellent reliability, torque, and longevity in demanding applications.
Featuring a 10 × 12 mm cross-section and weighing only 9.5 g, it is ideal for space-constrained designs where high torque is required. The D-shaped gearbox output shaft measures 3 mm in diameter and 9 mm long, while the motor also includes a 4.5 × 1 mm extended rear shaft, making it fully compatible with the Pololu 12 CPR Magnetic Encoder Pair Kit for Micro Metal (HPCB compatible).
