    Who sells ECM motors (1/4, 1/3 or 1/2 hp) and how much do they cost -
    (over-the-counter) ?

    Unless I'm wrong, they seem to only be available as integrated into
    HVAC systems (furnaces) and maybe only to HVAC
    installers/contractors.

    Are they sold to the general public- perhaps to those wanting to
    replace their existing AC fan motors?

    Bonus question:

    Do ECM motors radiate EM/RF noise, or back-feed noise into the house
    wiring?

    How does an ECM differ from what is called a brushless dc motor?

    Hmm.
    Other wise know as a DC brushless or AC motor?
