You may have assembled a new robot friend, added a computer for a brain and other fun personality touches. Now it's time to let him leave the nest and fly with his own wings - uh, uh, with wheels!

These durable (but affordable!) plastic gear motors (also known as'TT') are an easy and inexpensive way to get your projects moving. It is a TT direct current gearbox motor with a 1:48 gear ratio, and comes with 2 x 200 mm wires with 0.1" male connectors suitable for breadboards. Perfect for connection to a breadboard or terminal blocks.

You can power these motors with 3VDC up to 6VDC, they will of course go a little faster at higher voltages. We took an engine and found these statistics by running it from a stabilized power supply.

    At 3VDC, we measured 150mA at 120 RPM without load, and 1.1 Amperes in case of blocking.
    At 4.5 VDC, we measured 155 mA at 185 rpm without load, and 1.2 A when the engine is off.
    At 6VDC, we measured 160mA at 250 RPM without load, and 1.5 Amperes in case of blockage.

Note that these are very basic motors, without integrated encoders, speed control or position feedback. Tension in, rotation out! There will be variations from engine to engine, so a separate feedback system is needed if you need precision motion.

Delivered individually by order, with only the motor + wires. You cannot drive them directly from a microcontroller, a high current motor driver is required! We recommend the DRV8833 for these motors, as it works well up to 3V and can be configured with current limiting as stall current on these motors can be high.

We have a range of wheels, add-ons and accessories for these engines so you can use it as you wish.
