guys,
I ran a hot rotor on Nemesis in the early 90's and never had any
problems.
I used all metal and pillow block bearings, metal shaft etc. I used a v
belt off of the metal pulley to a metal pulley on the motor and then
isolated all on an insulated mount stand. I used a DC motor and an
isolation xfrmer at the gap. This is really cutting the death quotient
real
close. I had no problems over the 3 years of Nemesis' life span.
