Washing machine drain pump motor type

In summary, the person has recently changed their washing machine drain pump and is curious about the type of motor used. They mention that there is a transformer on the back but no visible brushes. Another person suggests that it is most likely an induction motor, specifically a Shaded Pole type, which may not be very efficient but is reliable and inexpensive. The original person thanks them and shares a website they found that explains the basics of AC motors.

Brush motors are a lot of hassle for that sort of application. It will almost certainly be an induction motor and the ones I've seen looked like Shaded Pole types. Not very efficient but trouble free and cheap and they don't run for long over the life of the machine.
