Washing machine motor types

[adamthemieleman]

Hello all, this is an issue that's causing me confusion. There's so many types of motors manufacturers seem to be coming up with. I have a basic understanding, just need a bit of clarification.

I assume the difference between an AC and a DC motor is the input current, the DC being able to offer a bit more control. They so use brushes to supply electricity to the commutator to drive the rotor obviously.

Here's where it gets complicated. What is the differences between an Induction, Brushless and Inverter motor?

I assume the Bosch Ecosilence drive is a reluctance motor with electromagnets driving a magnetic core. How exactly does the AEG permanent magnet motor work? Surely that would need some form of electro magnetism also?

Any guidance to clear up my confusion would be appreciated!

on an induction motor,the rotor is non-magnetic when motor is inactive-laminated iron rotor has aluminum bars and end rings in a "squirrel cage"pattern:as the AC stator magnetic field changes polatity,current is induced into the rotor bars near the coil changing polatity and that section becomes temporarily magnetic at that instant-causing the rotor to rotate-this all happens very fast and the number of stator poles and the AC current frequency driving the motor determines the RPM-3 phase power or single is used with induction motors-single phase needs a starting method to start rotation.Brushless is usually a permanent magnet rotor with a 3-phase stator-electronic circuit driving the stator with DC current,"hall effect"sensors mounted near the rotor magnets providing feedback to the drive circuit on rotor position,direction, and RPM.Inverter motors are 3-phase AC induction motors driven with varible frequency current-allowing variable speed and RPM much higher than avalible with mains driven induction motors that are limited to ~3500 RPM on 60 HZ power,~3000 RPM 50 HZ.More detail to come if wanted

Yes please, I like detail!

I appreciate the effort but I think I would prefer the more literate dumb downed version.
