Dull Men's Club
An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

Motor brush. Its a chunk of carbon that makes contact with a bit on the motor shaft.
Hol up. Do most washers use brushed DC motors??? Why? That's such a strange choice of motor for that application.
Value engineering: engineering the value right out of the product and into the shareholder pockets
I don't know about "most" but Universal motors use brushes and can run on AC.
Older front loaders i think. The speed and direction control is much simpler compared to modern BLDC.
I assumed they would just use capacitor commutated AC motors like most 'dumb' motors running on single phase.
I also assumed during the wash cycle it would just switch direction before the motor could accelerate to full speed, then the spin cycle was full speed. I didn't realize any more speed control was necessary.
BLDC?
Brushless DC, a type of electric motor that as the name states, does not use brushes.
I've done the same on our front loader. Though top loading machines are the exception rather than the norm here.
Hardest part of the job is just shifting the machine to get access. Once you're in, it's 5 minutes to swap them out and another 5 to scrub your hands after, because I'm an idiot that forgets gloves 🙃
