I'm buying a used cab machine from a friend, but it doesn't have a motor. I haven't had much luck buying used motors around here, but someone suggested a local appliance store for washing machine or dryer motors. I stopped by today and was told that it was illegal for them to sell me a used motor. So I immediately asked if they could give me a motor instead. The guy working there was an old student of mine and told me that if I removed it, it wouldn't be a problem. He then took me outside where he flipped over a new looking, but discarded washing machine. We couldn't really see the motor, but there was what appeared to be the bottom of one that said "3 rpm" on it. Do any of you happen to know what size motors are typically used in washers and dryers? This could be a really nice source of motors if they're the appropriate size. Obviously 3 rpm isn't going to be quite fast enough though.

I think furnace blower motors are more commonly used since they are mostly 1/3 hp and 1725 RPM. I have heard that dryer motors are meant to run vertically. Something about the bearings are different to hold the weight of the inner workings when tipped vertical..

I did find one furnace blower motor, but I called just about every furnace guy in town and was told by most that they can't be easily removed. I forget the term they used, but it was something about them being build right in or something.

I had a clothes drier go bad a couple of years ago. I went to salvage the motor and found that it was open. It did not have a case. The appliance guy told me that most modern appliances are that way. Anyway, my point is that it is getting more and more difficult to salvage motors from appliances. You can still find motors that you can salvage on on drill presses and table saws. I do not know if these are rated as continuous run.

Unless you are really into getting it cheap, I'd try places like Tractor Supply or Farm and Fleet. They occasionally place motors on reduced pricing and you probably can get something in your price range, new and totally suited. Just thinking. Here in the SW we can get old swamp cooler (evaporative cooler) motors cheap Used or new). You might want to try Home Depot's website. Tom

Thanks everyone. I'm not giving up on finding a cheap motor, but maybe washers and dryers are not the best route. Tom, I'll watch for sales at Tractor Supply, but I don't think swamp coolers are sold in Michigan. I had never heard of one until a couple years ago. I looked it up at the time and, if I remember correctly, they were only useful in hotter climates.

There's a seller on eBay with really cheap motors. Like really really cheap. I think he has a new 1 hp 1725 rpm for $55 plus shipping. His name is 80servo.

Washing machine and dryers "usually" use a 1/3hp 1750rpm (1725 with normal slip loss) they are open frame..washing machine motors "usually" are vertical mounted shaft-wise.. dryers horizontal. Both are continuous duty, but again, most are open frame motors. Furnace blower motors are rated only for being in the air flow...no fans on them! But are *easy* to remove.. usually one screw at the front of the little housing the motor and fan is mounted on and it will "slide" right out... get the corresponding capacitor with the motor. But some blower motors are 220 volt..some are 120volt. Newer energy saving washing machines *may* use a special motor that requires a speed control. Actually it's a DC motor with the speed stuff built into the non-drive end..but does have to have the speed control wires hooked up. Some of the newer outdoor AC compressor units use a similar type motor. Personally I would look for an old outdoor AC unit that has a decent fan motor.. they are sealed and heat resistant...kinda. Old style dryer motors would be good too if the open frame doesn't bother you. Too many washing machine motors need a special relay that handles speeds and *direction of rotation*.

I just pulled and hooked up two Maytag 1/2hp 1725 R.P.M. washer motors. Both are skeleton frame, so I built a "finger safe" cover out of non-conductive plastic that allows for plenty of ventilating air flow. The wiring diagrams are inside or on the back of washers and dryers, great help to figure running wiring; rotational direction and sometimes a hi-lo speed. If you get one of these and don't understand the wiring diagram, get some help. And, be safe w/the electricity.

Scrap metal operations that break down roof top units and separate the copper and aluminum coils, motors and steel are about as good a place to find motors as I have ever seen. Roof top units usually have fan several motors. Many are 208 and 220, but some are 110 Volt fractional HP. They often run at about 1000 RPM. The scrap yard often torches the fan blade off at the motor. So you need to catch them before that. The motors demand a higher price than the steel structure, so they are always sold separately for their copper value. Many scrap yards do not allow the public, but may be worth asking for permission.

Not sure if you could do this, but could you use a cheap bench grinder. I've seen them for as low as $30 to $40.

Thanks. I'll check that out. Have you ordered from him? Not yet, but I did have a conversation with him about picking up a motor instead of shipping. (I'm lucky that their warehouse is 20 min away.) He seemed OK. Only one catch. I was looking at that motor I told you about. It's a capacitor start but doesn't include the cap itself. That's sold separately (of course), but it still works out to be a good deal.

Check an AC&R shop in your area. See if they have any used swamp cooler motors. They're great for lapidary use.
