Question about a blower for forced air.

[heus]

OK electric motor gurus. I just removed a squirrel cage blower motor from a 60,000 btu Miller mobile home lp furnace. The motor is a Fasco 1/4 hp 4.0 amp, type u26 number 70261605 . I need to know if this is a shaded pole motor or at least a multi-speed motor. The problem is I cannot find any info on this particular motor online. I would love to control this with a rheostat. How can you tell by looking at an electric motor if it is a shaded pole motor?

Thank you delivron. From this info, it looks like it is not a shaded pole motor, right? That stinks because I will have to control the air with a damper instead of a rheostat.

I would contact them or one on their dealers those motors are under $100.00. Get the one you really want. I was watching a movie last night with lots of commercials has time to do your research. They have hundreds of small motors.

I am running a blower from the same furnace on my 2x6. I tried a dimmer switch on it for the first season. It worked ok but did not start well at slow speed. I now have the side of the blower that does not have the motor sticking out completely covered and run a regular light switch on it and it works great. My theory is run what you have.

Controlling flow with an inlet damper is cheaper and more efficient than a speed control.

Rileysugarbush answered your question to the "T". :cool:

I guess I will rig up a damper on the inlet side. Thanks guys.

Since mine is a PSC, can I use one of these solid state controls in the link? http://www.electricmotorwarehouse.com/kbwc.htm
