Frequency Converter SD2M Turbo

Standard converters in the higher power classes typically use the well-known technology of two-level pulse width modulation (PWM) with max. 8 kHz switching frequency. In most high-speed applications, this requires additional components such as LC filters or chokes to minimize the additional losses in the engine.

Highlights

  • Three-Level Technology

    Function:
    The output stages of SD2M Turbo are based on a three-level technology and provide rotating field frequencies up to 2,000 Hz with switching frequencies of 16 kHz.

    Advantage:
    Reduced motor losses combined with minimum efforts for motor filters and motor chokes as well as low interfering radiation and insulation stress.

    Benefit:
    Low system costs over the whole product life cycle.

  • Efficiency

    Function:
    The devices reach efficiencies of up to 98 %.

    Advantage:
    The high efficiency of the devices ensures optimal system efficiencies and reduces cooling requirements.

    Benefit:
    Maximum system output and lower environmental footprint due to lower energy consumption.

  • DC Supply

    Function:
    Active emergency braking and maintenance of voltage supply in case of power supply failure.

    Advantage:
    No separate voltage supply for the magnetic bearings needed.

    Benefit:
    Protection of the magnetic bearings in case of power failure as well as cost savings.

Applications

  • In the field of turbomachines, the system's efficiency can be continuously improved by increasing the system speed or omitting the gear. 

     

  • Due to their design, a large number of technologies in the field of waste energy usage or mechanical energy storage require high-speed motors and generators

     

  • Rotary atomization processes, e.g. applied for the production of milk powder or flue gas treatment, require high circumferential speeds. Therefore, it is necessary to use matching high-speed motors instead of low-speed standard motors.

     

  • Refrigeration units with turbo or centrifugal compressors with higher power ranges operate with high speeds. Frequency converters by SIEB & MEYER easily provide the required speeds and their control method ensures an exceptionally low rotor heating.

Standard converters in the higher power classes typically use the well-known technology of two-level pulse width modulation (PWM) with max. 8 kHz switching frequency. In most high-speed applications, this requires additional components such as LC filters or chokes to minimize the additional losses in the engine.

The Booster

SIEB & MEYER frequency inverters are specially designed for high-speed applications and use the three-level technology - also called multi-level technology - which is very advantageous in these applications.

As a rule, no motor filter elements are required when using our SD2M Turbo inverter series. This is due not only to the three-level technology, but also to the fact that we supply PWM switching frequencies of up to 16 kHz as standard. The combination results in a significantly improved motor current quality, which extremely reduces the unwanted rotor losses - by up to 90 %!
