L-Shaped DC Gear Motor 2A120-BLK – 1:120 Reduction, 3V/6V, 90-Degree Gearbox

The 2A120-BLK is an L-shaped DC gear motor that combines a brushed DC motor with a 90-degree gearbox to deliver reduced speed and increased torque in a compact, right-angle form factor. The gearbox provides a 1:120 reduction ratio, making the motor suitable for applications where high speed is less important than controlled, powerful rotation. It operates at two nominal voltages: at 3V the no-load current is ≤170 mA and the no-load speed is 55 ±10% rpm, while at 6V the no-load current is ≤250 mA and the no-load speed is 115 ±10% rpm. The L-shaped design places the output shaft at 90 degrees to the motor body, which allows the motor to fit into tight spaces and short-wheelbase robot chassis where a straight gear motor would not align with the wheel axle. The unit is described as encoder-ready, meaning it can accept an encoder for position or speed feedback in closed-loop control systems. Typical uses include DIY robotics, educational projects, remote-controlled toys, and small automated mechanisms. This L-shaped gear motor is a practical choice for builders who need a right-angle drive with a defined 1:120 reduction and dual 3V/6V compatibility.
