DC Gearbox Motor - "TT Motor" - 200RPM - 3 to 6VDC
All prices are VAT included
Perhaps you've been assembling a new robot friend, adding a computer for a brain and other fun personality touches. Now the time has come to let it leave the nest and fly on its own wings – err, wheels!
These durable (but affordable!) plastic gearbox motors (also known as 'TT' motors) are an easy, low-cost way to get your projects moving. This is a TT DC Gearbox Motor with a gear ratio of 1:48 , and it comes with 2 x 200mm wires with breadboard-friendly 0.1" male connectors. Perfect for plugging into a breadboard or terminal blocks.
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 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 variation 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 + wires. 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.
