Engineered (Electrical) Drives

Customised Variable Frequency Drives (VFD) or engineered VFD solutions for Medium Voltage (MV) or Low Voltage (LV) applications

Siemens engineered (also known as electrical) drives designs are based on combining proven electronic modules with customer specific switchgear, cabinet requirements and cooling arrangements. This guarantees that performance specifications regarding ratings, enclosure type, ability to withstand environmental issues and supply authority limitations are adhered to.

Details

Engineered drives may be designed to incorporate various switchgear options including supply circuit breakers, line or load side switches/contactors and earthing switches.

Siemens offers a comprehensive range of variable frequency drives, also known as variable speed drives (VSD), including the Robicon Perfect, Harmony HV, Micro Harmony, Sinamics (GM150, SM150, G150, S150, S120), Micromaster, Fuji and Emotron.

 

Siemens also offer harmonic filters integrated into VFD cabinets, automatic by-pass of faulty modules, closed synchronous transition from VFD to fixed frequency grid power and regenerative and resistor type braking.
