Metal DC Geared Motor w/Encoder - 6V 300RPM 3.6Kg.cm

The Metal DC Geared Motor with Encoder is a reliable 6V drive unit combining a 20:1 metal gearbox with an integrated Hall-effect encoder. Delivering a stall torque of 3.6 kg·cm and a no-load speed of 300 RPM, it is an ideal choice for students, makers, and hobbyists building closed-loop mobile robots and smart automation mechanisms.

Integrated quadrature Hall encoder

The built-in encoder operates at 3.3V or 5V and provides 11 counts per revolution of the motor shaft. Coupled with the internal gearing, it delivers a precise resolution of 224.4 counts per revolution at the output shaft for accurate position and speed control.

Metal gearbox performance

Equipped with a 20:1 reduction ratio metal gearbox, the motor achieves a stall torque of 3.6 kg·cm with a 2.7A stall current at 6V. It operates at maximum efficiency under a 0.7 kg·cm load at 245 RPM while drawing just 0.4A.

Compact form factor and D-shaft

The unit measures 50 mm in length by 24.4 mm in diameter and weighs 96 g. It features a standard 4 mm diameter, 8 mm long D-shaped output shaft for secure mounting to wheels, gears, and couplers.

Wide operating voltage and versatility

Although rated for 6V, the motor can initiate rotation at voltages as low as 1V for flexible speed control. It is well suited for differential drive mobile platforms, robotic chassis, and automated IoT mechanisms such as smart blinds.

Included connection cable

Each motor includes a matching JST 6-pin cable to easily break out both motor power leads and encoder signal lines to your driver and controller.
