Rather having to continuous change belts on my 16" floor model Jet drill press, I purchased a new 1HP/240v/3-phase Baldor motor ($75 on ebay). It's inverter rated and reversable. To power it, I got a new Teco VFD from driveswarehouse. The VFD can be programmed up to 200Hz (default is 60Hz), which pushes the motor from it's rated 1780 RPM to around 5900 RPM. My question is how much faster can one safely run a good (Baldor) ball-bearing motor. Could I push it to 3000 RPM (~100Hz) since a drill press is typically less than an hour per job? The motor is a TEFC so heating should only be a problem at the really low RPMs. Any help would be appreciated.
