With your 5" drive pulley you'll have about 2350 SFPM belt speed at the 1800 rpm motor speed. With the 3600 rpm motor and 5" drive wheel that would be around 5700 SFPM belt speed. Just fine for profiling, but a real bugger to finish a knife with. I'd go with the 1800 rpm motor, 2350 will cut pretty good with cheap belts - not ceramic.
The unload speed is for when you have no load... ¿Comprende? Not to discourage you, but an angle grinder motor is the wrong motor for this application. You need low speed, high torque and variable speed. Use a brushless DC motor from a cordless drill or impact driver/wrench. Angle Grinders are AC and single phase.
Depending on the type of motor your grinder has, it may need to a control that varies frequency to slow it down, rather than reducing voltage. A little reduction through a rheostat could create a lot of heat, which can wipe out the windings quickly. 1971BB427, Dec 21, 2013.

Mar 3, 2013. Messages. 1,399. Aug 11, 2020. #5. I believe the Jet variable speed grinder is a 3 phase motor with a VFD. The Delta says it is an induction motor, it might also be 3 phase with a VFD but... it also lists a separate capacitor in the parts list, has a relatively low price and a limited speed range...
Model 80-808: 8″ Low Speed Grinder. 1 HP Low Speed Bench Grinder #80-808 is a larger size motor and will tackle the tough grinding jobs that are typical in production shops, as well as the finesse shaping and sharpening of hand tools. Tool rests on this machine are extra-large and flat, without a drill bit sharpening groove.
Re: Grinder speed control I think it can be done but you need a speed controller designed specifically for induction motors. It would likely be cheaper to buy a new grinder. Also, it's not good for the motor and could over heat it. There are speed controllers for ceiling fans which have induction motors but it's a different type of wiring then a grinder motor and it's built for that …

That is a DC open frame motor ( probably from a treadmill). It is a very poor choice for a grinder motor. Both the HP and the speed ratings are misleading. The HP on those things is "Rated HP", similar to 3HP routers and 5HP vacuums. The plate says it would "develop" 2HP with the motor running at 6100RPM and at 130VDC.
A common application of servos is in robotics & CNC machines. I believe the advantage of a servo motor here is 2 things, the ability to control speed along with being able to mount the burrs on the motor shaft. All the other speed controlled grinders use some sort of transmission and a second shaft to mount the burrs.
Burr grinder motor speed. An electric burr grinder with a high-speed motor might sound like a great deal – especially if the cost is fairly low. But in truth, you're more likely to find higher speeds on cheaper burr grinders. Why? Because a high-speed motor produces more heat, which can actually burn the coffee beans as they're processed.
From what I've read and my own experience as a machinist, I will design this grinder to have belt speeds of between 15 and 30 m/s. Most operation will probably take place between 20 and 25 m/s.
Their automatic grinders run on an average of 2 HP motor speed, giving you enough motor speed to cut through all of your foods with ease. Weston is a great manufacturer for beginner and professional chefs alive. Kitchener. The Kitchener is a manufacturer that helps users find ease when cutting through meat.
Motor Speed: Though the speed of a grinder will rely on the horsepower of the motor, and it is measured in terms of revolutions per minute (RPM). A grinder wheel with a minimum speed of 3000 RPM will spin at a faster rate that let you cut through stronger metals and hardened steel. While choosing a grinder with a speed of at least 1750 RPM ...
Motor speed. Motor speed is another excellent way to judge the bench grinder performances. This is the number of wheel rotations per minute. High motor speed equals faster grinding. Motor speed varies from one bench grinder to the next. It can start from a low of 2000 RPM to a high of 3000RPM. Make sure you consider bench grinders with higher ...

A pro-grade belt grinder generally uses a 1750 RPM motor with 0 - speed controller. Meaning most of work is done at much slower speeds. However, the real metric we are concerned with is the linear speed of the belt - usually measured in surface feet per minute (SFM).

Turn grinder on and let it come up to full speed. Turn grinder off, make your passes until wheel stops. Repeat as needed. I sharpen all turning tools this way. When grinding a plane iron or chisel, if only a touchup is needed, do the same thing. If the chisel needs a lot of work, grind at 3450 rpm until you get close, then use the previous method.
Most bench grinders run at about 3,450 rpm, although there are more and more variable speed grinders on the market these days. If you're careful and keep the wheel dressed, a high speed grinder will work fine for you. However, for sharpening blades, a low-speed grinder running at 1,750 rpm is a much better choice.
