This seems to point at a "constant torque" configuration as opposed to a "constant HP" which I think is more common. I have some questions maybe you can answer. 1. Breakdown torque is an increase OVER max rated torque in which slip would increase in the motor to achieve that. Spindles...

No worries Mike, just did not want to start from the "understanding AC power" handbook....lol I am really trying to understand what special parameters are used in the machine tool spindle systems. Something I have noticed is these motors typically are smooth body so they must have some type of...

I certainly don't design drives but I am more familiar with them than most and specify settings on some. I am not quite sure what you are getting at though. Typically even in scalar modes and open loop, a drive would have a pretty linear V/hz ratio but might push the V for torque boost when...

Sorry for that guys! wrote up a post earlier today only to see it dumped by the Inet gremmies! I have a question regarding machine tool spindle design. It has come to my attention that some premium designers actually specifically use under voltage motors or have them made that way so they...
