Motors are optimised for use with frequency converters

26 March, 2014

At next month’s Hannover Fair, Siemens will be launching a family of motors designed specifically for use with frequency converters.

The Simotics VSD10 motors, based on the existing 1LE1 platform, will be available in both aluminium (Simotics GP) and cast-iron (Simotics SD) versions and will cover the output range 2.2–200kW.

The motors, which will become a key component of Siemens’ Integrated Drive Systems portfolio, are optimised for use with its Sinamics G120 frequency converters. The company says that the optimum coordination of components will result in cost-effective systems, characterised by reliable operation and high availability.

Siemens says that the strengths of the integrated approach will be apparent during commissioning. Motor codes on the rating plates will provide pre-defined parameter settings for the Sinamics converters, simplifying and cutting the costs of commissioning and avoiding input errors.

The motors’ windings are matched to the power modules of the Sinamics converters. Temperature sensors are built in and the motors have insulated bearings for large shaft heights. The ability to control the speed of the motors will be a particular advantage in applications involving partial loads – reducing their energy consumption, especially if the inverter's energy-saving functions are used as well.

The drive systems can be integrated into Siemens’ TIA Portal via Profinet.

♦  At Hannover, Siemens is also extending the upper power rating of its IP20-protected G120P inverters from 90kW to 400kW.
