3-6VDC Hobby Gearmotor


3-6VDC Hobby Gearmotor


SKU: ROB-113


Using a basic DC motor to drive a wheel on a robot can be a bit tricky. Small DC motors tend to have a very high shaft speed, very low torque, and no easy way to connect to a wheel. These all in one “TT” Gearbox Motors take care of everything!

The DC motor is coupled to a 1:48 reduction gearbox in an easy to mount assembly. On each side of the gearbox there is a 5.5mm flatted output shaft – these can be used to connect wheels and rotary encoders. The “no load” output shaft speed is approximately 120 RPM at 3V and 250 RPM at 6V. An ideal speed for a small roaming robot!

These motors cannot be directly driven by an Arduino, Raspberry Pi, micro:bit, or other similar microcontroller or single board computer. A motor driver will need to be used – if you are just getting started, we recommend one of these:

Arduino: Adafruit Motor Shield

BBC micro:bit: SparkFun moto:bit

Raspberry Pi: Adafruit DC / Stepper Motor HAT

Please Note: Wheel and Encoder Disk sold separately.
