This is one of those questions that you just hate to ask! My motor is giving off a burning smell. I think that it has been doing it for a while but I typically wear a respirator so I did not notice it. What is the long and short of it? Will it quietly die or will it flame out spectacularly. What should I be looking out for?

You may let the smoke out of the motor! :eek: Then it will be dead! I’m not an electrician , but you may not have a motor that’s rated for what you are asking? Plus points for wearing a Respirator !! You are a smart man!:thumbsup:
 
check connections, sometimes things come loose and have to be reconnected
 
I will check the connections. I am running a 1hp 1800 rpm at the 3600 rpm setting on my controller. I have 6" drive wheel so I am pushing 5600 SPM. It ran fine for two years.
 
Its hard to say without seeing it, but check its connections and if anything gets abnormally hot. It wont be surprise if you are just overloading.

Btw, If its TEFC, when it croaks, it should not flame out, just release some smoke & die.

Ahhhh, since you're running a 1 hp motor at 3600 rpm thru a 6" drive wheel, bet you're overloading the motor, especially if you'll pushing much pressure on the belt while grinding. When you smell the motor, lay your hand on the housing - bet it's hot.
 
Is your motor inverter duty? Is the chassis getting hot to the touch? I agree with Ken, you may be asking a lot from a 1hp motor.

Oddly, it never heats up. And I agree, it is too much to ask from a 1hp motor. I was just starting out and didn't want to add a 220 line. I can easily bottom out the motor. I will upgrade to a 2hp shortly. My plan is to use the 1hp and the VFD to make a 9" disk sander. I have orders waiting and just haven't had time to make the changes. The only good thing about mechanical failure is that it leave you no choice to make the right decision. Thanks for checking in.
