Treadmill motor questions

Yes and I want one of those big fans for my shop next summer. I found the perfect motor. Small 1/19 go 1550 rpm came on a squirrel cage fan off of some appliance. The shaft is 3/8” same as the trimmer. All mounted on a 10” long 2x6. Neat and fits in a drawer. The motor is 4” diameter and 4” long. All free from our hvac guys at work. It’s brand new. I googled it and they cost $ 100.00 Online. It will be mounted and switched today. Now just waiting on the WFT trimmer. For a shop fan you don't want one with a slant wall kit. You'll need to look at some from an old farm that shut down. A lot of the older farms had box fans attached to the wall. Slant wall fan boxes are wider at the top than the bottom so they point toward the ground more.

Thank you and that’s good information to know.
Gonna have a couple machinist questions in a bit.

 Tredmill motors are torquey but I don't think they don't go 1700RPM easy.
 You can use a J6 belt on the stock pully.
 But the pully is so small.

 I have one running my little old atlas lathe.

 I kept the old controls and it has speed control and several safety features.
 I can clip the cord to my waste and if I fall down while working on my lathe it shuts off.
Don't tell OSHA or they will make that manditory.


 They do make a nice DC generator if you can spin them fast enough.
You can get them up to 250 volts DC.


 

Best use of a treadmill motor setup ever.

I’m thinking that may be the ticket would be small and quiet

Joe I’m preparing a whole bunch of brass for reloading.
I’ve found a neat trimmer I want to buy. It just chucks in a drill and you can clamp the drill down and let it run.
Drills are noisy and not made to run for long periods of time.
I’m trying to find a light quiet motor that runs 1725 Rpm and s doesn’t take up much room.
Last week I turned a collar to fit an electric ice cream maker and added a drill Chuck to it. I use this for reaming primer pockets and chamfering. Wish I had 3. I ran it for several hrs straight Sat**day.
It’s way too slow for trimming but perfect for chamfering and reaming.

Went to the shop for a bit. Messed with the motor. It appears noisy and bulky with all the garbage to make it work.
I think I’m gonna find an small AC motor that’s 1725 rpm and clockwise rotation.

i would think if you have a cheap shroud around the fan / motor , that it would make air flow for cooling.. pushing or pulling.
