Most of these vacuum motors run way too fast.  You could reduce the speed
with a pulley/belt arrangement allowing the motor to develop full torque and
reducing the speed on your RSG setup which could be held in a pair of pillow
block mounted bearings (McMaster-Carr).

If you are running a pole xmfr then just use a standard 1725 RPM 1/2 HP
motor with a 14 inch G-10 disk (electrodes on 12 inch centers) with approx
10 electrodes.  This provides very good performance.
