belt grinder motor choice and speed control

Belt Grinder - Motor Choice - The Home Shop Machinist ...

2020-2-11  02-11-2020, 12:57 PM. IMHO, a 1" belt grinder needs a minimum of 1HP. VFD control preferred. Max speed 120 Hz on a 4-pole sheaved to get at least 4000 FPM on the belt. 5000 FPM preferred. A 4" belt needs at least 2 HP with same speeds. 3 HP motor is better. RWO.

The "Cadillac choice" is appreciated by many makers.
