I have a treadmill motor o plan to use for a project. First off it needs reversed. I believe I can switch leads and make it work. The fan will then turn the wrong direction. It has a plastic fan on one end and a flywheel pulley on the other. I plan to run it without the flywheel and it would need to run continuously for an hour or so at a time. Not a heavy load. Do I need to find something different. Doesn’t have to be variable speed. |

i would think if you have a cheap shroud around the fan / motor , that it would make air flow for cooling.. pushing or pulling. ------------- Like them all, but love the "B"s. |

Ok... what I know... usually 'free' as everyone gets rid of them once they're in great shape.... I've had 4 or 5 over the years... 'treadmill motors' are usually 90 V DC motors. As such easy to reverse ( swap red and black wires). A DPDT switch rated for 120VDC / 10A will work, just be SURE mot is NOT spinning when you change direction......oospy, POOF, lots of smoke.... hmm, could you mount the motor the other way, physically ? That changes the direction. Without the flywheel, it'll be 'jerky' depending on the load. Check the rating on the motor, most of the ones I've played with are 3500-4500 RPM. Always best to grab power supply and controller WITH the motor. Newer ones seem to all have the same 'controller' and easy to modify for speed control. LOTS of info about using them,schematics, etc. easy to find when you have part numbers.... ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

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. |

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. |

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. https://flic.kr/p/2iL4epP" rel="nofollow">  https://flic.kr/p/2iL4epP" rel="nofollow - lathecoupler by https://www.flickr.com/photos/147103123@N05/" rel="nofollow - vwfatmobile , on FlickrI 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. https://flic.kr/p/2eLNDfi" rel="nofollow">  |

EASY, if you use the 'controller' that was on the treadmill or a variable DC power supply. ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

With as many chicken farms as there are in Arkansas you can surely get a used fan motor somewhere for a song. The 36 inch exhaust fans usually have 1/2hp, 120/240, CW/CCW, 1750 RPM motors with a 1/2" keyed shaft. Might be bigger than what you want but it's an option. ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

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. ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |
