Hello everybody, are there any dishwashers with powerful ac pump motors anymore? I know that the Maytag and Whirlpool point voyagers still use them. What do you think of them and how they sound and perform? Inquiring minds want to know. |

As the alternative would be a d.c servo or hall sensor sinus motor pump which would be more costly to manufacture. They also require a p.c.b board. |

What do you think of the new dishwasher motors from Whirlpool? I believe their Maytag line has the AC motor still, like their older point voyager line. What about their global wash system? |

Yes we can. I think AC motors are better because they startup quickly. This is especially true for their point voyager line where they seemingly startup instantly. |

It's my understanding the Whirlpool's current filter platform dishwashers are not using DC motors.
But AC "wet permanent magnetic rotor" synchronous motors with some kind of load feedback system for the controller. They do have some electronics in them as well. See here: www.repairclinic.com/Part... www.woodgears.ca/motors/wet_roto... They are very small, use very low wattage, but seem to really pack a power punch similar of older, larger motors. According to the 2nd link, these run at about 3600rpm. This little "pond pump" really sprays water around in my KitchenAid with force. And regardless of the "soft start" to get the permanent magnet moving, it's perfectly unnoticeable whereas it seems like it starts up instantly. I doubt you'd ever notice the difference. GE and Frigidaire are currently using DC brushed motors in their dishwashers. They are fed AC power too, but they have a built in transformer on the back of the pump. I despised this pump in my old GE machine, because it totally gave off that brushy DC whine. It also made a pile of brush dust under the machine. |
