MOTOR GENERATOR SET TECHNOLOGY

In many existing rolling mill facilities, Motor-Generator (MG) sets remain a viable 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.

IMS has implemented a variety of motor and generator configurations:

Single Generator/Motor
Multiple Parallel Generators and Motors
Rolling Mill Common Bus Systems

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

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
