X13 has the electrical efficiency of the ECM but has fixed speeds like a PSC. Many equipment makers are using it to help boost SEER but you don't get variable speed. They work like a standard motor. Just use less juice which is important these days.

 

Is that what Trane uses on the new XT lines of furnace?

 

Does'nt Goodman use these motors in thier new equipment now?

CW.

 

Should be the motor Trane & A-S use on the T models. Don't know about Goodman.

 

Thanks BaldLoonie,

Seems as if GE plans for these to replace PSC.

I wonder if the X13 can be used to retrofit standard systems without an additional board. (rectifier/power regulation built in?)

 

No,

Just like an ECM, the X motor is powered all the time by line voltage and low voltage switching selelcts the speed. They are more a constant speed motor, versus a constant CFM motor. Their blower curves look more like a PSC than an ECM.

Th programming cosists more of RPM, not Torque vs. RPM like an ECM. There are typicly 5 connections for low voltage on a X motor but they may not all be programmed on any given motor. You need to use the correct motor.

Also you might be hard pressed to find a GE X motor. Regal Beloit (bought GE's motor division a couple years ago) has their name on it. You may see "GE by Regal Beloit". Ge has allowed them to keep the GE name on the ECM's for the time being.

 

X13 GE motors

I work for a HVAC distributor and I've seen a couple of X13 motors fail because the magnets came loose from the rotor. The MFG said the problem was fixed in Feb. 07 but I'm not sure it's resolved. anyone had similar problems?

I love the X13 motor. More efficient than a true variable speed motor for less money. But for maximum benefits, such as dehumidification and motor ramping, the true variable speed motor is the best!!

I have not had any trouble with failures on the X13 motor.

 

X13 loose magnet

This came out of a Rheem packaged unit that was installed less than two years ago. The shaft turns freely, but only about fifteen degrees then it hits something internal. I guess that must be the loose magnet.

 

my GE X13 motor failed today due to broken magnets. I pulled it out the HVAC unit myself.
