Variable Speed Coupler control application was specifically developed to provide control for the Voith Vorecon RWE and RWC variable speed drive units. The Voith Vorecon RWE is the “compact” version of the Voith Vorecon, offering a speed control range of 60 – 100% of the electric motor’s nominal speed, and suitable for driven loads of 1,000 – 50,000 kW. It uses a planetary gear arrangement and a torque converter. The Voith Vorecon RWC is suitable for applications with a higher driven load, or where it is desirable to reduce the start-up torque as much as possible. This is achieved by adding a hydrodynamic startup coupling to the RWE arrangement.
The Vorecon Speed Control (VSC) application was designed to have all the necessary I/O and functionality to interface the Vorecon. The VSC application’s primary function is to regulate the speed of a compressor to a desired set-point by modulating either the Vorecon’s Torque Converter’s inlet guide vanes (IGV) or the Vorecon’s Hydrodynamic Start-up Coupling’s scoop tube position to ensure that the compressor speed remains within a safe and acceptable range. The VSC application includes the following features:
