3V - 6V Dual Axis TT Gear Motor
"TT" gearbox motors have been popular since we carried the TT motor + wheel kit back in 2018, many have feedback for us to carry the motor itself, so here you are the yellow "TT" motor. This is a TT DC Dual Axis Plastic Gearbox Motor with a gear ratio of 1:48, which will provide nearly double the speed of the Blue metal TT motor that has a 1:90 gear ratio. Of course, you can always control the speed via PWM from Arduino or any microcontroller with a suitable motor driver. These motors are being used in building mobile robots, for example, Bocobot:
You can power these motors with 3VDC up to 6VDC, they'll of course go a little faster at the higher voltages. We grabbed one motor and found these stats when running it from a bench-top supply
- At 3VDC we measured 150mA @ 120 RPM no-load, and 1.1 Amps when stalled
- At 4.5VDC we measured 155mA @ 185 RPM no-load, and 1.2 Amps when stalled
- At 6VDC we measured 160mA @ 250 RPM no-load, and 1.5 Amps when stalled
Note: These are very basic motors, and have no built-in encoders, speed control or positional feedback. Voltage goes in, rotation goes out! There will be variation from motor to motor, so a separate feedback system is required if you need precision movement.
You will need a suitable motor driver to drive this motor as microcontroller cannot drives it directly! Here are some of our recommedation:
