I've just taken a similar motor form our (now dead) washing machine. I took the whole harness and all the electronics from the machine, so I may be able to get it on the bench and give it a push and a prod sometime. It seems to me that the motor rpm is greatly affected by the load. My knowledge gets sketchy at this point, but I have read of control/regulation being via back emf, used in a feedback loop inside the controller. What puzzles me is how rpm and feedback seem detached under no-load conditions. Nice motors, though. Mine is labelled C. E. SET and its 800W 17000rpm. The controller was made by Jabil Circuit who used to have a factory about 3 miles from here. The washing machine was a Hotpoint. We've had several, and they are not that great. But I have to say that when I took it apart, the engineering design of many of the components impressed me greatly. All that clever design to make the thing easy and cheap to manufacturer. The drum mouldings are worthy of a design museum.
What controller are you using?
