Cleaning a Vacuum Cleaner’s Universal Motor Commutator to Reduce Sparks (and Stink!)
Lindsay Wilson had a vacuum cleaner with some gunk buildup on the motor’s brushes/commutator, a common experience with any piece of machinery used over a period of time (or if you keep a furball pet around). He disassembled the device to give it a proper cleaning, and in doing so also took a look at the unique suction mechanism (2nd image below, also in the video) used by this particular vacuum cleaner.
The vacuum cleaner in the garage was making one hell of a stink and producing a lot of sparking – seems that some gunk had become trapped in the motor brushes/commutator, burnt and caused the brushes to start sparking excessively. I stripped the whole thing down and gave it a clean up.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
