Mike ... yes; I have been intrigued by the 2 separate motors myself. I don't know about their "types" ... I'm afraid I'm not well-versed in electric motors.
It looks like Chuck and I have the same model ... A50. I think Chuck's might be "newer" because of the impellers. The impellers on mine are hard, black plastic and I think Chuck's are a gray colored hard rubber. Please correct me if I am wrong, Chuck. I remember the one that I bought was white like yours and had the gray impellers.
These machines can (and do) tangle clothing if you don't have the right "mixture" of items. I noticed that if I wash a queen-sized sheet in it without pillowcases, the sheet comes out really twisted. If I wash a load (like the one in my pictures) that is a mixture of a large towel, wash cloths, a couple of undershirts, etc., it does not tangle as much.
The manual reads sort of like the wringer washer manual ... add clothing only as long as their is free movement in the wash tub. The manual also states that a load that fits nicely in the wash tub will also fit in the spinner.
I'll have to find out about the rpm's of the impellers. They are really quick and churn the water quite a bit. They pause every 30 seconds and then reverse their direction.
It reminds me of a front loading machine. It uses only 11 gallons of water to the bottom of the black splash bar.
Small in capacity and in height; it can be a real "back-breaker" for the taller person!!
