Motor on My Champion blower burnt!

[RonnieT]

I have an old Champion Blower, I think is a #50?
It has a small looks like a Westinghouse 1/15hp motor on it that is now burnt.
Its possible that it could be an AC/DC motor.
The speed dial is also old and gives problems.
Can this be updated to something newer and more reliable? Like an AC motor with some type of newer variable speed switch?
It has a 3/8" shaft on the fan with only a flat on the shaft for the set screw.
Any ideas or recommendations?

If the motor has brushes, it is a uni ersal motor, i.e. ac/Dc. Motor controllers for this ype of motor are usually of the type which reduce voltafe to reduce speed. The problem with this is if you cut the voltage in half, the power is dropped to one quarter. That being said, I assume you don't want to invest several hundred to use a 3ph motor and a VFD. You can replace the motor with a like size and a speed control (Harbor freight has them for less than $20). The other optionsare: is find a multi speed blower motor with the approiate dimensions and install a multi-position switch to change speeds, or go to a DC motor and a speed control.
The Surplus center is a good place to start. http://www.surpluscenter.com

You could throttle air flow instead of motor speed with a gate valve, or a choke plate.

Slowing down the motor also slows down the cooling fan on the end of the motor

thank you, that brings up a few questions,
yes it does have brushes so it must be an AC/DC type.
What are the Harbor freight motors that have the controllers, I have never seen them?
I do buy from Surplus center I can ask for a blower fan there.
Now what is a gate valve, or choke pate, and can I make one?
Thank you for the replies to my problem.

Thats too bad about your motor. Those things are quite the robust beast what could take alot of low voltage abuse.
Never seen one 'burnt out' without a lot of neglect or outright abuse as its root cause.
Anyway, good luck getting a replacement to mount up & couple to its fan.

Btw, in this context, "chokeplate" is a device choking down fan intake. "gatevalve", an adjustable restriction on fan output.
Its to leave a motor running at fullspeed & adjust airflow to the fire. No hard construction rules on it, skys the limit on how a guy wants to cobble up those things.
