Ok, so a 3/4 hp motor is harder to stall, seems logical to me. What's the point you are attempting to make?
Kindly be concerned about your own safety, thank you very much, I was born at night but not last night.

most of the production belt grinder, I seen and used are between 3600 to 8000 fpm, I've seen in a catalog a version that went to over 10,000 fpm. A belt break at that speed has to be exciting. I have a 2 x 48 Jancy RadiusMaster, that runs at 3600 fpm, that will remove metal at an alarming rate. Belt speed is only part of the equation, high quality belts are a absolute necessity, I use nothing by Norton, with ceramic grit on a fabric backer. Cheap belts render a belt grinder almost useless.
I have a Rockwell/Delta 6 x 48 belt sander, that speed is about 1200 fpm, a good unit, but rarely used, since the Jancy arrived in the shop.
