These plastic gearbox motors, also known as TT motors, are a simple and affordable way to get a small robot or wheeled project moving.
This DC gearbox motor uses a 1:48 gear ratio and includes pre-attached wires with breadboard-friendly 0.1" male connectors, making it easy to plug into a breadboard or terminal block while prototyping.
It runs from 3VDC to 6VDC, with higher voltages giving higher speed. These are basic motors with no built-in encoders, speed control or positional feedback, so use a separate feedback system if your project needs precision movement.
You cannot drive this motor directly from a microcontroller; a high-current motor driver is required. A DRV8833 motor driver is a good match down to 3V, while a TB6612 can also be used if you supply at least 4.5V.
Specifications:
- Gear ratio: 1:48
- Wires: 2 x 200mm wires with breadboard-friendly 0.1" male connectors
- Power: 3VDC up to 6VDC
- 3VDC performance: 150mA @ 120 RPM no-load, and 1.1 Amps when stalled
- 4.5VDC performance: 155mA @ 185 RPM no-load, and 1.2 Amps when stalled
- 6VDC performance: 160mA @ 250 RPM no-load, and 1.5 Amps when stalled
- Included: 1 x per order, with just the motor + wires
Pair it with suitable TT motor wheels and a compatible motor driver to build a compact mobile robot, buggy or kinetic project.
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- Terminal block
- A terminal block is a connector that joins wires together in a neat, removable, or serviceable way, usually clamping each wire under a screw or spring instead of soldering. It makes it easier to connect, change, or service wiring without permanent joints.
