    Description

    "TT" gearbox motor is popular, now we carry another model of "TT" motor. It is more durable yet remains affordable! This is a TT DC Dual Metal Gearbox Motor with a gear ratio of 1:90, which is about double the 'standard' 1:48 ratio. That gives them higher torque but slower rotational speed. Since they're slower they're good for robots where strength is more important than speed. These motors are being used in building a mobile robot, an example in one of Cytron BocoBot:

     

     

    They look a lot like the yellow all-plastic-gearbox "TT" motors but these have the output half of the motor gears machined from steel, so they won't strip as easily, and they're twice as slow (and twice as powerful) given their lower gearbox ratio. The metal gears also mean they're louder when running.

     

    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 80mA @ 60 RPM no-load, and 0.5 Amps when stalled
    • At 4.5VDC we measured 90mA @ 90 RPM no-load, and 0.8 Amps when stalled
    • At 6VDC we measured 100mA @ 120 RPM no-load, and 1.0 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 variations 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 a microcontroller cannot drive it directly! Here are some of our recommendations:
