Efficiency drive
May 1st 2007

WEG Electric Motors says drive shafts.

its MVW-01 range is setting benchmarks for medium voltage drive efficiency, achieving 99% with a new design that uses Multilevel Topology to minimise component levels, and high voltage (6.5kV) IBGTs to reduce motor harmonic currents to low levels.

Introduction of the MVW- 01 drives means WEG can offer a total package, including input switchgear, dry or oil-filled phaseshifting transformer, VSD and medium voltage motor.

Unlike many MV drives which have 3 or 5 layer control, the WEG MVW-01 range has just two layers.

The company says the benefit of this is a reduction in the number of components in the drive, and commensurate improvements in efficiency and reliability.

The drives are Voltage Source Inverters employing the latest multi-processor control architecture. they are designed to deliver high levels of reliability and low noise levels (<75dBA).
