New Approach for Intelligent Motor Control Centers

As steel operations rely heavily on low-voltage motors, the introduction of new technologies which target motor performance have a direct impact on energy, commissioning and maintenance costs. Networking allows for easy monitoring of critical data of
each motor or load connected to the intelligent motor control center (iMCC), enabling precise process control. However, the iMCC concept isn’t a new technology. Networked protection relays and speed drivers are mature technologies with consolidated acceptance. Explore new trends for iMCCs including new Ethernet technologies, Web, wireless, biometric devices, and new technologies for metering and motor branch circuit protection.
