In many existing rolling mill facilities, Motor-Generator (MG) sets remain a viable variable speed drive subsystem. IMS is an expert in the modernization of these legacy drive systems using modern solid-state digital motor and generator field excitation and PLC control.
The PLC is the heart of the MG drive control implementation. This includes the software implementation of:
Motor Speed Control
Motor Torque Control
Motor Armature Current Control
Motor CEMF Control for Extended Speed Range Operation
Fault Monitoring of all Key Operating Parameters
IMS has implemented a variety of motor and generator configurations:
Multiple Parallel Generators and Motors
Rolling Mill Common Bus Systems
A digital upgrade to a legacy mg set drive subsystem provides the following benefits:
Improved Control Accuracy
Improved Dynamic Performance
Enhanced Protection and Troubleshooting
Digital Network Interface to New or Existing Supervisory Control Systems.
