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.
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 🙃
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.
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.

BLDC?
Brushless DC, a type of electric motor that as the name states, does not use brushes.
