Description 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 pre-wired “TT” Gearbox Motors take care of everything and are a breeze to hook up! 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. This is the fastest version of the TT motor we carry – ideal for a small roaming robot! The motors are pre-wired, and do not require any soldering. The wires measure approximately 20cm and are terminated with breadboard compatible male pins. 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. Please Note: Wheel and Encoder Disk sold separately.
