This is a TT DC Dual Axis Plastic Gearbox Motor with a gear ratio of 1:48, which will provides nearly double the speed of the Blue metal TT motor that has 1:90 gear ratio. Of course you can always control the speed via PWM from Arduino or any microcontroller with suitable motor driver
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 recommendation:
