Automation and control technologies for electric motors

The best automation and control technologies for electric motors: these are the demands of the metal sector, one of the biggest energy consumers on the entire industrial scene.

Gefran provides this sector with engineering know-how, proposing drives to control AC and brushless motors as well as armature converters for DC motors.


The trend in industrial networks and the automation market

Communication in industrial automation is now the real strategic tool for increasing a company’s productivity and efficiency because it provides an effective way to transmit quality data between different automation systems, to control machines and synchronization, monitor production lines, etc.

How was this achieved? And what will tomorrow’s trends be?

Case Histories for Metal

Metal - OEM, System Integrator, End User
SAG - Slitter and cut-to-length lines

SAG - Slitter and cut-to-length lines

SAG uses roll forming machines with flying shear system.
The production speed creates various design problems regarding mechanics and movement control. Gefran studied for SAG a highly dynamic control system.

Metal - OEM
Faccin - Plate rolls

Faccin - Plate rolls

For over 60 years, Faccin has been the leading manufacturer of plate rolls, angle rolls, and production lines for dome ends. In the metal plate rolling process, it is extremely important to control the main process parameters, such as roll position and oil pressure and temperature. Gefran is Faccin’s ideal partner because it offers a complete range of sensors, from position to temperature, to satisfy the customer’s needs.
