wiring up a grinder motor.... couple quick questions

This motor is trickier than my Dayton. I can't get around the problem of disconnecting at least one of the lines with the switch, there is now where to do it because neither line 1 or line 2 is ever connected to red or black. The type of Drum Switch Stacy mentioned may be better for your aplication.

This switch can handle switching the red and black wires no problem, but because it doesn't include either line 1 or line 2, the problem, as stated earlier, is that the motor stays energized. I would definitely add a 2HP motor switch before the motor if you do it this way. You can get a 2HP 377 VAC switch at Lowes or HD for $5. I actually prefer a master on/off and mine is wired with one.

Here's the best I have with what you've got.

To reverse the motor, the red and black wires are switched. They are each either connected to blue and grey, or orange and white. If you look at your switch, the middle row is what changes when you switch from forward and reverse. In your wiring diagram, Line 1 goes to yellow/black and Line 2 goes to yellow and they don't change.

Here's a diagram to wire the drum switch. I did this before recognizing that we weren't cutting power anywhere, so you would need to wire a motor switch to cut off the power supply. It would be in my diagram in front of the motor at the power supply.

Yes, that is a reversing switch. You wire the CW and CCW wires to it. The power wires L1 and L2 are wired straight to the motor. You will need a motor switch, AKA starter switch in the power lines.
To use it you turn off the motor, throw the drum switch, turn the power back on. Even though the drum is center off, the motor stays energized, so it would be a bad idea to rely on the drum as an ON-OFF switch or to change the direction while running.

Edited to remove the wiring info - , alb1 posted it already.

Indeed I did with you guys' help. Looking at it now it all seemed so obvious! :)

This thing is a seems a lot more powerful than my old 2HP DC unit I built back in 04. Course, with the DC I could start it slow and ramp up speed... This one at its fastest ratio just starts screamin as soon as I hit the switch. Gonna take some gettin used to.

thank you again Erik, your help has made our name look good. ;)
 
If you get a VFD ( variable frequency device) it will do all you want and more like slow speed to full speed settings , forward / reverse , overclocking and whatnot. Something to think about and it's easy to wire if you follow the manual. There are lots of different brands to choose from. In my limited experience I was able to wire it and I'm no electrician and like having control of everything the motor does. Too bad the motor died and I'm waiting on a replacement drive wheel which is going to cost the same as the new motor I got for a steal. The owner bought it and couldn't figure out how to wire a 3 phase so it sat in a box for 2 years and has 0 hours on it . In the future a pulley system with VFD is what I'm going to make / buy. Way easier then being stuck to a wheel.

His motor is a single phase, I think you need a 3 phase motor if you want to use a VFD ??? I am no electrician though
