Siemens: Strong team – Integrated Drive Systems for pumps, fans and compressors

Integrated drive systems facilitate efficient and economical operation of pumps, fans, and compressors. The perfectly matched Simotics FD motors and Sinamics G120P frequency converters demonstrate their strengths as an Integrated Drive System (IDS) from the planning and engineering stage to operation and service.

Siemens offers a broad range of drive systems for all applications that use pumps, fans, and compressors. Motors and drives support global standards such as IEC, UL, CCC, or ATEX and can be flexibly adjusted to all performance classes and environments. The operator is supported and advised by a team of experts from Siemens when planning the overall solution.

The Sinamics G120P frequency converters, particularly suitable for use with pump, fan, and compressor applications, work in perfect synchrony with Simotics FD motors, for example, when it comes to determining the rated pulse frequency of the converter. Full advantage can thus be taken of IDS at all stages.

Time-saving engineering

For the greatest possible engineering efficiency, a consistent system configuration is necessary. Here, Siemens offers the possibility to configure not only the motor but also the converter using the Sizer configuration tool. Alternatively, for simple configurations, the drive components can also be configured with the DT configurator. As the coil of the motor is perfectly tailored to the converter’s output currents and the voltage, oversizing the drives can be avoided. This reduces investment costs by up to 15%. In addition, quick and easy engineering with TIA Portal reduces engineering time by up to 30%.

Energy-efficient operation

The advantages of IDS also become apparent during commissioning. Faster commissioning is possible due to the converter’s preinstalled commissioning wizards, which already include specific functions for pumps, fans, and compressors as well as application macros that are available on demand. In addition, theSinamics G120P has predefined parameters for the new Simotics FD motors that were especially developed to operate the drive. With frequency converter controls and pulse patterns that have been optimized forSimotics motors, noise emissions are reduced by more than 4 dB, lowering the costs for noise insulation. Moreover, the innovative Sinamics G120P converter technology and the matching of the motor’s rated currents with the converter’s output currents help reduce motor losses by more than 10%. This leads to the highly energy-efficient operation of pumps, fans, and compressors, and costs are sustainably reduced with every operating hour. Over the service life of the plant, these savings can completely offset the acquisition investment of the drive. Compared to less energy-efficient systems, this can result in the full amortization of essential parts of the plant. Isolated motor bearings as well as a coildesigned especially to feed the frequency converter increase the motor’s service life and, consequently, plant availability. These well-matched components ensure reliable operation and high plant transparency for the operator.

Service increases plant availability

Last but not least, operators using IDS also benefit from the single-source service concept. In addition to reduced effort when stocking spare parts and long-term spare parts availability, foresighted maintenance with Drive Train Condition Monitoring extends the service life of the motors, increasing plant availability.

Highlights:

• Up to 15% investment reduction by avoiding oversizing

• Increased energy efficiency, with a reduction of losses of at least 10%

• Reduced noise emissions, by more than 4 dB, which leads to reduced costs for noise insulation

• Up to 30% reduction in engineering time with quick and easy engineering in TIA Portal

• High plant availability due to longer motor service life and Drive Train Condition Monitoring
