Adding to our collection of somewhat specialized motors, this Rotating Door Lock Motor is a DC Gearbox motor with a little pocket that is intended for a door look mechanism. The motor only turns 90 degrees clockwise or counter-clockwise and will stall (but not strip) if you try to keep running it past the angle.
It's geared down so it has high torque, but that also makes it slow - it is about 5 seconds for it to rotate 'closed' or 'open'. That said, we like that you can power it from approximately 5V so its easy to hook up to your microcontroller or computer using Crickit and Arduino, CircuitPython or MakeCode.
Constructed with four mounting holes and runs quietly. We don't have any more specs or documentation for this beast.
Jargon buster
Plain-language definitions for the technical terms used above.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- 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.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
