The article presents a comparison regarding the features of the mechanical variable-speed drives (MVSDs) and variable-frequency drives (VFDs) in the process control equipment industry in Australia. It highlights the advantages and disadvantages of using MVSDs over VFDs. It informs that hydraulic torque converters MVSDs are not recommended forrotating machines. It mentions that selection of drives depends on several factors including the optimization and operation costs.
