I would call it a Constant Velocity Blower. It maintains constant velocity(static pressure) unless the filter gets extremely plugged up or the ducts are grossly undersized in which case it will cavitate/hunt. I have never had any customers get confused about it and we have sold thousands of them. I usually tell my customers it is a high efficiency motor which uses 80 watts on low speed and show them the huge energy savings vs a PSC motor and they buy it for that reason.
Not you, all of the rest. I was being fasicious to all of the others who swear that VS motors have nothing but problems when I know, and evidently you do too, that most issues occurring with VS motors is not the motors fault.
Sorry I didn't make myself clearer. I was complimenting you as being the "one" who doesn't have issues. Am I still the Great One?
The X13 motor has the advantage of being a less expensive blower motor to operate and will operate constantly at a lower speed for constant air circulation, but those are limited benefits of what ECM motors are really capable of.
A variable speed motor is the same as the X13 motor, except that it has a lot more control features that can greatly increase comfort and overcome minor system issues.
