Dishwasher Motors For Ebikes?
First thing is to identify what the motor actually is. It has two wires and a ground wire. The coils are two in number and they wrap around an iron laminated core. I'm unable to see inside to look at the rotor, but my guess is that the rotor is a permanent magnet.
Using RC motor terminology my guess is that this is a brushless "outrunner" motor. The size is about right for ebikes as can be seen in the photo.
Now one can ask:
"Why not just buy a high quality brushless RC motor and start there?"
...and my answer would be:
"Yeah, that's probably true..."
---------------------
I think it's interesting that these exist and can be gotten for free because of the large number of dishwashers in the world. Efficiency is likely not very good though, since it's running off of the grid.
Why just two coils?
Since it's designed to move water (which is heavy) you would think that it would need to have some pretty good low end torque.
I wonder if something so simple and minimal could be used?
(no brushes to wear out)
