Step 1: Choose a motor package.
Regardless of the voltage you choose, all of their machines plug into single phase power.
For the variable speed 1.5hp and 2hp options, the motors and drives are the same, but the 110V option limits the output to 1.5hp rather than the full 2hp. You can always re-wire it to run on the other voltage any time you want to take advantage of the full 2hp. Please contact us for instructions on how to do so to avoid damage to your motor or speed controller.
Step 2: Choose a Drive Wheel for your motor.
Which Bore Size should you pick?
If you are supplying your own motor, choose the bore size that matches the shaft of your motor. Our single speed motors have a 7/8” shaft and our variable speed motors have a 5/8” shaft. If you are getting a motor from Ameribrade, we will make sure your drive wheel matches your motor even if you accidentally choose wrong.
Which Outer Diameter should you pick?
4 inch: (We recommend this size for single speed grinders)
Pro: Lower Cost
Con: Lower belt speed (3800 feet per minute) does not remove metal as quickly
Pro: Lower belt speed reduces burning while working with wood and allows for some small wheel usage on single speed grinders
Note: We recommend this size for single speed grinders
7 inch: (We recommend this size for variable speed grinders)
Pro: higher belt speed (6600 feet per minute) is great for metal stock removal
Con: Must be slowed down with a variable speed drive in order to prevent damage to bearings on wheels under 1.5" diameter in a small wheel holder
Con: Higher Cost
