Top spindle speed for this model is 1,240 RPM. That sure seems slow. Is it?
I'm replacing the stock motor with a 2HP 3 phase 4 pole motor and adding a VFD. It's a new motor with a Streans brake that I guess is old stock because it has class B wiring. Can I overclock it to say 90 Hz to get the top spindle speed to 1,860 RPM?
Also I just noticed the new motor has no fan because of the brake. It's sealed with no cooling fins. That doesn't seem good in any circumstance.
Lastly the original motor has a 2.25"-3.88" 2 step pulley with a 3/4" bore. The new motor has a 7/8" shaft. Unbeknownst to me 2 step pulleys are not common and I can't find one close to what I need. I never suspected that the pulley was going to be a problem. Boring the existing pulley out would leave the bottom of the 2" pulley 1/8" thick. That seems to be pushing it. Any suggestions?
