Energy savings with SINAMICS variable frequency drives
How energy-efficient drive solutions help reduce your operating costs.
Due to high energy costs and the need to reduce CO2 and greenhouse gases, energy- and resource-efficient applications in the drivetrain are becoming increasingly important. SINAMICS variable frequency drives offer energy-saving functions that make your consumption transparent, harness your energy conservation potential, and optimize your energy consumption to improve production efficiency.
SINAMICS drives are the ideal choice for sustainable production. Their versatility offers you a wide range of functions for optimizing energy efficiency, with savings of up to 60 %. Discover these comprehensive energy-saving functions now and see for yourself how easy energy efficiency can be.
Increase energy efficiency with SINAMICS Low Harmonics drive functions
A Low Harmonics drive system minimizes harmonics in the power grid – and improves grid quality and energy efficiency.
Our Clean Power drives – like the SINAMICS G220 Clean Power – with an integrated two-quadrant active front end realize a total harmonic distortion in current of under 2% and negligible reactive power. The entire grid and connected equipment benefit from optimal power quality and operating conditions, which results in reduced energy losses and greater reliability. They also comply with the most stringent harmonic standards, including EN/IEC 61000-3-12 and IEEE 519. Simply select the "Clean Power" version of a SINAMICS drive to benefit from this Low Harmonics technology.
An integrated feature in the Active Line Module (ALM) regulates and controls the flow of reactive power between the drive system and the power grid. It enables the drives to convert almost 100% of the power they draw to actual work. This integrated feature at the drive level eliminates the need for expensive reactive power compensation systems and reduces energy losses, ensuring enhanced energy efficiency and cost-effectiveness in your operations.
SINAMICS variable frequency drives with motor efficiency optimization
Motor efficiency optimization is a key factor in increasing energy efficiency and sustainability in industrial drive systems and helps to reduce operating costs. The SINAMICS variable frequency drives offer a wide range of energy-saving functions for optimizing motor efficiency.
Benefit from maximum flexibility thanks to machine openness, and achieve your system's full potential. Effortlessly third-party motors and ensure an efficient operation by reducing energy losses by up to 15 %.
Motor identification allows the easy implementation of synchronous reluctance and permanent magnetic motors. The Motor Control Extended function – a highly efficient and high-performance encoder-less closed-loop control – unleashes full motor performance from standstill to nominal speed. Activate and use both via the Web server or SINAMICS Startdrive.
The innovative control function in the drive uses the difference in the required voltage to adjust the magnetic flux. It is activated effortlessly via the drives' engineering.
The ECO Mode function slightly changes the magnetic flux of the motor and reduces the output voltage to improve the operating point with the minimum input power. This function is especially appropriate for machines with a lower torque and lower dynamic power that do not require high motor torque over the entire operating range. Reduce motor losses at partial load and the motor's associated heat losses. Simply activate ECO Mode in the frequency converter menu. In case of load changes, you can easily switch back to dynamic control.
