Control apparatus and corresponding method for controlling a high power electric motor, preferably of the order of megawatts, preferably of or associated with a shredding plant which is preferably usable for shredding very bulky and heavy objects and is provided with a rotating shredding member connected to the rotor of the electric motor, where a control circuit is configured to control the electric motor so that it can operate selectively in different operating modes.

Control apparatus and method to control a high-power electric motor

A device for the hot measuring, during rolling, of a transverse size of a metal profile () includes a transmission element with at least two sections distinct and spatially separated from each other and disposed along a nominal axis of feed of the metal profile, configured to generate an electromagnetic field with a desired profile of force lines, and a reception element disposed along the nominal axis in a position comprised in the overall longitudinal bulk of the transmission element () and configured to detect a signal relating to the variations of the electromagnetic field due to the passage of the metal profile.

Device and method for the hot measuring, during rolling, of a size of metal profiles

A method for the hot measuring of a transverse size of a metal profile to obtain a diameter and/or a mean thickness includes providing power with a sinusoidal current having at least two frequencies, a transmission element having at least two sections distinct and spatially separated from each other and disposed along a nominal axis of feed of the metal profile, generating an electromagnetic field with a desired profile of the force lines, and detecting a signal relating to the variations of the electromagnetic field due to the passage of the metal profile through the sections of the transmission element using a reception element having one or more sections distinct and spatially separated from each other and disposed along the nominal axis in a position of the transmission element.

Method for the hot measuring, during rolling, of a size of metal profiles

Method and device to manage a coiler apparatus associated with a distributor, in which there is at least an exit of the feeder of hot or cold semi-worked metal products, and with a reel, both being respectively moved with suitable controlled movement and rotation means, able to manage the coiling obtaining coils with desired characteristics.
