TT Motor Gearbox – 1:120 Gear Ratio
This “TT” Gearmotor is a compete DC motor and 1:120 Gearbox in one convenient, easy to mount package!
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 1:120 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 48 RPM at 3V and 100 RPM at 6V. This is the mid-range version of the TT motor we carry – a balance of torque and speed.
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.
