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.
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.
