Frequency converters and variable frequency drives for every drive application

The all-rounder to comply with standard requirements for all drives with low voltage motors. Frequency converters with and without energy recovery are suitable for a huge range of applications. For example, if materials must be moved, processed, positioned, pumped or compressed. Variable-speed operation saves energy and also increases process quality and process availability.

MV drive converters for motor voltages in the range from 1.4 kV up to 13.8 kV. Medium-voltage drive converters for high-voltage motors are used if the required drive power and/or voltage is too high for low-voltage drive solutions. However, they are also used to address special applications.

These servo drives address the highest dynamic requirements when it comes to single and multi-axis applications. The specialists for machine tools, packaging machines, continuous material webs, cranes, rolling mills, test stands, material handling, robots and many other applications where high precision, dynamic motion control is demanded.

DC drives based on SINAMICS DC – including motors with the highest dynamic performance and power density, DC supplies for excitation equipment for variable-speed synchronous motors.

Efficient and user-friendly configuring, commissioning, engineering and parameterizing. With intelligent engineering tools you can leverage the full power and performance potential of your frequency converter system, and therefore your complete drive.

Our vfd drives can be centrally installed in control cabinets, mounted on walls/panels or decentrally installed (on motors)

Here, you can access the original manufacturer's data for variable frequency drives.

By simply entering the converter article number in the DT Configurator, you can obtain CAD data such as 3D models and 2D dimension drawings.

Today, state-of-the-art frequency converter and drive functions are implemented using software. This software is also called firmware. For SINAMICS drives, the firmware is split up into one area with the operating system (OS) with drivers for the hardware, and in another area with the frequency converter functions, which are also called runtime (RT) functions.

Maximum safety for operating and maintenance personnel: The safety functions are already embedded in our SINAMICS converters. Your benefit: Shorter response times and a higher degree of cost effectiveness with lower wiring costs

All of the drive elements are perfectly harmonized and coordinated with one another – from SINAMICS variable frequency drives through SIMOTICS motors up to SIMOGEAR gearboxes and couplings. Our frequency converters can be optimally interfaced with control systems such as SIMATIC, SINUMERIK and SIMOTION. Communication is established quickly and safely via PROFINET. Thanks to the holistic approach of Totally Integrated Automation, not only do you save time and costs, but you can create a permanent and decisive lead in your specific competitive environment.
