Bought a 1.5hp Leeson Farm Duty TEFC motor. Have little experience with electrical. What I do know is I need it to run on 110v and that I need a cord to do so. Motor has no "On/Off" switch and no power supply/cord. Talk about intimidating for an electrical noob like myself. Could they make this purchase any harder? Now I know what it feels like when my parents are intimidated with computer technology. What do I need to $$buy$$/do now to make this thing work? *sigh*
 
Forgot to add that i'll be running this with step-pulleys... actually bought the those correctly, including the belt. :rolleyes:

Thanks in advance. :)
 
well here's the wiring diagram based on my best guess on what model you got from the Leeson website. http://www.leeson.com:5000/drawings/frontpage/leeson/00505302.pdf
I'm pretty lost as to what it means but it's a start. If you get the model/leeson part number off of the motor and put it in on the site it should come up with a spec sheet and connection diagram if this isn't the right one. Maybe someone with some knowledge of what that diagram means can take it from here.
 
Open up the electrical plate on the motor. Most have a wiring diagram for 110v and 220v. All I did was pick up a heavy-huty plug rated for the amps that the motor pulls, wired that through a on/off switch and plugged it in. Seems to work just fine for me!
 
Go get a 25' heavy extension cord and cut the female end off. Strip off 2" of the outer insulation jacket, cut off any lose paper or string. Then strip about 3/8" of insulation from each of the 3 wires. You also need to pick up some wire nuts. These are plastic tapered cap looking things with a metal piece inside that you twist wires together then place the wire nut on and twist it on the wires. you want ones for 14-16 gauge wire. You also want a 3 1/2" wire clamps, a metal switch box with 1/2 punch outs, a single position single throw switch and a metal cover to match. Ask for help at the electrical dept of a hardware store. The clamps have 2 screws on one side and a short threaded pipe and a round skinny nut with tits on the other. The pipe end goes thru a punch out hole in the motors box and 2 in the switch box and the nut holds it to the box and your stripped wire goes thru that. Under the cover of the box there will be some wires all numbered. There will also be a diagram with those numbers. Connect the wires to together as shown for 110 or low voltage. Your white and black are probably refered to as L or P it doesn't matter which is white or black. Connect your wires to the correct wires with a wire nut, then join all the remaining wires together and use a wire nut to secure. There should be 2 numbered wires that will control direction of rotation. 1 goes to your power and the other with the remainder. If you pick the wrong direction simply unplug the motor and change those around. Connect the green wire to a green bolt or a lug with the symbol that has several lines that get shorter producing a pyramid. Before you plug in the motor the first time, you need to go as far away from the motor as you want your switch and a little extra and cut your wire and strip both ends as before. Knock a couple holes in your switch box and connect wire clamps to them and insert the wires. Connect the 2 white ends back together and wire nut, On the wire nuts, twist till they tighten up some and I usually give them and the wires an couple wraps of black electrical tape for insurance. Now connect the 2 black ends to your 2 switch screws and the 2 greens wires go to the green screw on the switch. If there is no green screw simply connect both green wires together. Screw the switch to the box and the cover to the switch and your all set to test your motor direction. Happy grinding. Jim

PS wait till you connect up your first VFD.
