VFD for grinder Practical Machinist

Sep 16, 2005· Below that torque drops off very quickly. A vector-type VFD can provide full torque down to around 1 Hz or better. Torque will also drop off above 60 Hz. In a grinder application however, the grinding wheel is like a flywheel, and has a lot of inertia when at full speed, compared to when running at half speed for example.

Motor and VFD for Belt Grinder The Hobby-Machinist

Jun 07, 2017· I finally got my belt grinder wired up last night. I bought a KBAC-27d VFD and a 2 horse Leeson. I bought these as a package on Ebay. The motor hesitates, on/off at low frequencies up to about 20%. KBAC said I need to send the VFD in for software upgrades as the motor is an energy efficient one.

Old grinder VFD/motor upgrade. BladeForums

Oct 06, 2020· The 1hp motor "should" be enough for decent grinding with the contact wheel. The KBAC (and other cheap Chinese VFD) are running on 1 ph (single phase) and converting to 3 phase voltage to run a standard 3 ph motor. Typically you would purchase a 3 ph, 240/460 motor to use with the VFD.

720 RPM motor on a VFD Electric motors & generators

Jun 04, 2020· I have a customer who wants to reduce the speed of a large grinder. He wants to use a VFD to drop the speed about 20%. They're grinding ceramics so there is fairly low torque involved, usually something on the order of 10% of what the machine was designed for. In my opinion this does make this a reasonable candidate for VFD slowing.

Is there ever a need to use different spindle RPM on a

Feb 13, 2016· I'm just getting ready to fit a VFD to my surface grinder. The native speed at 50hz is about 2900rpm. I have a stack of 6" wheels which have a higher speed rating so I can fit a pot to control the spindle speed and my idea is to surface mount it somewhere prominent and make a scale that reads in RPM, but is it realistically going to be useful or an unnecessary complication?
