In THIS thread (post #22) I succeeded in making this motor run. (see post #11, third diagram).

Running it at 75% is way more air flow than I wish and would like to figure out how to slow it down. Does anyone KNOW how to slow this motor down?

(NOTE: refer to THIS thread (same as above))

I would suspect that if this is a typical ECM motor, you would need to dig deeper into the commutation control circuitry and see if this can be modified?
Probabally np mean task!
