Curious if anyone has a setup similar to this?
If you are going to build this, I highly recommend putting thermal protectors on the motor and also if possible hooking the motor up to 208v
your absolutely correct kevin.. most would not have 3 phase and altho you can find single phase 240v bimetallic thermal overload switches, they are way more common in the industrial setting. my supply house is closed or I would have given them a call just to get an idea of the cost for a single phase compared to a 3 phase. in any event you can use a 3 phase setup, you just wouldn't use the third one. the switch itself is just a reset button once the bimetallic material cools down. it is the bimetallic material that is protecting the motor. I can tell you that every motor I ever hooked up in my career had thermal overload protection, not to be mistaken for overload protection" your breaker". what thermal overload does to those who don't know, it breaks the contact when it reaches a critical level for the motor killing the power to the motor without kicking the breaker or running it until you cook the motor, think about it, you have a motor working flat out for hours maybe in which it wasn't really designed for. when you bog a motor down for long periods of time, like anything they heat up. they are kinda like your sensors on your car letting you know your engine is hot. there is a reason for that and if you keep running it your engine will kabuki out. . having a good motor rewound isn't cheep nor is buying even a crappy replacement! I cooked my bandsaw motor and gave the Rikon guy an earful on how valuable they are keeping a motor running under stressful loads. well come to find out lol he engineered the thing. just my 2 cents.99% of the members will not have 3Ø service.
