High Speed Motor Benefits
Variable SpeedDrive (VSD) M
CompressorTransformer
Gear-less drive Gear losses, costs, reduced lube oil system.
Flexible operation Variable speed drive Easy maintenance VFD has less than 30 minute MTTR.High reliability TMEIC VFD has very high reliabilityContinuous Operation System is designed for running 5 years
without maintenance.Global Service Electric Drives are easily supported 24 x
7 with people and remote diagnostics.
