New Developed Multistage Variable Speed Drive (MSVD) Of High Economy For The Speed Control Of Pumps With Power Up To 40,000 HP
The multistage variable drive, called MSVD, the latest development of a hydrodynamic mechanical drive system is presented. The special characteristics are high efficiency, excellent reliability, and availability, which are typical features for hydrodynamic drives. The drive is described in detail, the physical features are presented and the measured values of the prototype, type variants, application possibilities, fields of application and references are shown.
