saw one at a thrift shop --looks like the motor casing[open frame] is glued
togeather--has a water pump at one end--nice big coils in there thou..
4 start and 4 main...1/2hp 6 or 7 amps..

I've got a couple one from a GE the other from a Kenmore look very similar the thing that intrigued me was the wire size and the variable speed fields the wire size is at least 14 gage and the open frame is easily accessible .The magnet size to match the stator segments will be large and the rest trial and error. I though about using 3/4 or one inch buttons( rare earth) embedded into the existing rotor ( drill holes into the rotor and glue them in adding more as needed to get the flux flow that works ). their High torque motors
I assume they have bushings . I haven't taken them apart .I made a pack to not take any thing more apart until ready to finish the project turn key and I'm looking for a convenient
bearing replacement . Any Ideas there?

Two disadvantages - Some of the washing machine motors cannot be disassembled, and the open construction would have to be weatherproofed somehow.

Hiker I must agree with Electric Ed. These motor are built cheap and are a one time through away item. You could build a can to hold them and new end caps with bearings or just visit you local plumer a get a free Garbage disposal. These have a large diameter bore and are easy to convert and they allready have the can and its easy to make 3/4" end caps.

When you center the stator there is exactly 3/4" left over on each end. There are many 3/4 HP and they are rated 7.8 amps.

When you concider 7.8 amps X 120 volts the = 936 watts plus when you add in the power from the start windings another 200 watts, then reduce for looses and rpm losses you'll still end up with 500 or 600 watts top end at 25 mph. Charging starting at 5 MPH.

This has been my expirience with the curved NEOs and Jerry blades anyway.

The washer motor most likely has aluminum wire also.

Jerry;

Very good points on those open frame glued together motors.

I had one I used to drive a one lung compressor to charge a portable air tank. It did not last and when I finally burned out the windings they were indeed aluminum. The bushings wore out really fast too and while it still ran it was very loose in the shaft to bushing gap.

Cheers.
