I was talking with some friends about control technology and made the observation that over the last decade the progress in the control field has been really amazing.  Particularly, the processor technology that is available for controlling electric motors is operating 1000 times faster than the control platforms of a decade ago.  We look at […]

Another aspect of applying electric motors to power mechanical systems is the relationship between peak power and continuous power.  In mechanical systems the forces required to start a load may have no relationship to the power required to keep the system running.  Further, the  ideal demand for mechanical power may occur at a speed that […]

The SPS Drives show in Nuremberg Germany is one of the best attended shows in the world.  And one of the reasons why has to the with the outstanding technical effort and preparation that all the vendors put forward.  Demonstration systems are sophisticated and perform flawlessly.  Exhibitor personnel are all very professional and technically astute.  […]

Here’s a quick look at your options when selecting drives for use in machine tools. In machine tools, typically the details of the installed drive technology are concealed. In principle, however, there are several possibilities for main, feed and auxiliary drives to carry out the needed machine movements. Main Drives Main drives are predominantly closed-loop […]
