I shouldn't be able to stall it easily. But I can.
Some one suggested it might be the circuitry and wiring.
I have original 1927 wiring in my house. Is it any way I can check if
my wiring can handle the load? I have a multimeter.

Thanks,

What does the motor data plate say? Do you have a picture of the data
plate? What voltage is the supply in your house?

How did you stall it? With a long wooden stick or what?

It's a metal 2x72 grinder. I can stall it by grinding small piece of steel or aluminum
quite easy.
I have 115V in my house.

It's a WEG motor model #00158ES1BF56C.
