Germany: Siemens is extending its Simogear portfolio with a new synchronous-reluctance drive system consisting of Simogear standard gear unit, Simotics reluctance motor and a Sinamics frequency converter for controlling speed. The product has an output range of 0.55 – 4kW and is available for Sinamics G110M, G120D, G120 and S120 converters.

The engineering company says that its efficiency class is comparable to IE4 and it is offers advantages in comparison to asynchronous motors when operating under partial load due to its greater efficiency and lower losses. In addition, the drive system is characterised by high dynamics due to the low moment of inertia and optimised control. An external fan is not required due to the constant torque/speed curve up to the nominal speed and the drive system is certificated to CE, UL/CSA and CCC is in preparation. It also says that commissioning is easy as the motor code can be entered into the convertor.

Siemens sells a portfolio of frequency converters, motors, couplings and gearboxes for many industries and applications, including the cement and mineral sectors.
