Are you talking about a variable speed blower motor? ICM?
Still requires a 120 or 240 volt input.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
None run on 24v.
ECM motors use 24v control signals to the module on the motor, but have a line voltage input for powering the motor. The line voltage is rectified to DC, then is pulsed to the motor windings. The module varies the frequency of the pules to control the RPM.
The X13 motors have "speed taps" that are 24v inputs to select the speed, but have a line voltage input too. The X13 motor is still an ECM motor, just with a module that only runs the motor at fixed speeds.
Both types of ECM motors are far more efficient than regular single phase PCS or shaded pole motors, and have very significant performance advantages.
That sounds like it's right.I was told this type of motor was far more efficent and I would notice the savings on my hydro bill.Is there a specific manufacturer that uses that type of motor or will it just be specified in the the details of the furnace and what specifically should I be looking for that says it's that type of motor?Thanks for all input thus far.
