Siemens Sinamics SM150 Variable Frequency Drive

Manufacturer: Siemens

SINAMICS SM150 is a high-end drive converter for low and high speed applications. This is the reason that it is recommended for applications requiring a high dynamic performance and regenerative feedback into the line supply - generally with special motors from approx. 4 - 26 MW.

The water-cooled SINAMICS SM150 drive converters, capable of regenerative feedback into the line supply, are available as either single-motor or multi-motor drive with well-proven IGCT power semiconductors for medium-voltage drive applications. For the multi-motor drives, a common DC bus allows direct energy exchange for applications that involve both motoring and generating drives.

Features Applications Model

Easy plant integration due to the compact design and highly flexible configuration
Simple operator control with the user-friendly operator panel
Smooth and reliable operation due to the integrated maintenance functions: the converter signals automatically and well in advance when maintenance is required and/or components need to be exchanged
High ruggedness and reliability thanks to the use of IGCT technology and fuseless design, combined with intelligent response to external disturbances
Hassle-free integration into higher-level automation systems due to PROFIBUS interface supplied as standard and analog and digital interfaces
High degree of service-friendliness due to the innovative power section design with compact phase modules and excellent accessibility of all components
Ideal for direct energy exchange on the common DC bus in applications with motoring and generating drives

Moving: Belt conveyors, ship's drives, test stands
Processing: Rolling mill drives
Further, the power section is also used in Transrapid and traction power supply links. The non-regenerative version GM150 (IGCT version) is available for ship's drives, gas compressors and ore crushers.
