correct, while there are workarounds such as a variac- would work for speed- with all of these you are suffering loss of power with loss of RPM. What you would do best with is a tri phase, DC perm mag, even an old treadmill motor and controls. So you get constant power under torque- I confess I didn't read what were building, but I saw a grinder and if you need the power of a grinder motor- you need to pick the right motor first for speed control to not limit your power.Japanese-Whetstones and physics it's all just a sea of particles.
