Get your projects moving with these affordable and durable bi-metal gearbox motors, also known as 'TT' motors. The TT DC Bi-Metal Gearbox Motor has a 1:90 gear ratio, providing higher torque and slower rotational speed compared to the standard 1:48 ratio. This makes them ideal for robots that require strength over speed.
These motors have a similar appearance to our yellow all-plastic-gearbox motors, however they have steel output gears that make them more durable and resistant to stripping. With a gearbox ratio of 1:90, they offer half the speed but twice the power. The use of metal gears also results in a louder running noise.
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 that 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.
Comes 1 x per order, with just the motor. These motors do not come with wires attached, so you'll need to solder wires on yourself.
You cannot drive these directly from a microcontroller; a high-current motor driver is required! We recommend our DRV8833 motor driver for these motors, as it works well down to 3V and can be set up with current limiting since the stall current on these can get high. The TB6612 can also be used; it's on our shields and wings, but you'll need to supply at least 4.5V - which is what you'll likely want to run these motors at anyhow!
We have a range of wheels, add-ons, and accessories for these motors so you can bling out your bot just the way you like.
