Combined solution

Control Techniques' Unidrive M, in tandem with a Leroy-Somer Dyneo permanent magnet synchronous motor from Emerson Industrial Automation, is being used on a process-critical extrusion machine in order to help boost both the efficiency and accuracy of its work for customers in the plastics and chemical industries.

Among the technical features of the Unidrive M600 that appealed to Clariant was its ability to support sensor-less open loop control. This mode offers impressive dynamic performance and enables more compact and higher efficiency motor technologies to be used, such as Dyneo. It also supports simple positioning without the need for encoder position feedback.
