    Hello

    When faced with the necessity to buy a washing machine, I read many opinions on various topics. Drum types, durability, electronics problems etc, but no one has commented on the superiority of one type of motor over the other.

    From what I can see most washing machines have "brush" motors, and for example the AEG 72850 boasts of having an induction motor on every occasion.

    Therefore, the question: Which of the motors is the advantage of the washing machine, induction or "brush"?

    Inductive is less failure, it mainly replaces the bearings and has greater resistance in the event of an unexpected stop.

    The induction is almost silent, while the brush one can achieve greater stability and smooth rotation.

    In addition, inductive, heats up a little less, easier to control from the point of view of the components controlling it, quieter (no commutator noise). However, the brush motor is more powerful, the washing machine can regulate its revolutions much better, they are very stable, and their dimensions are smaller than induction motors and often cheaper.

    Hi!
    Of course, the induction motor has practically no emergency and is very quiet, but to change its speed you need an inverter, it is an additional module of the above-mentioned AEG, and therefore an additional element that may break and it is not so rosy.
